Description

[0001] The present invention relates to a system and a method for providing a GIS interworking evaluation appara- tus,

More particularly, the present invention relates to a system and method for evaluating a real estate property using a GIS based on transaction history or current market prices of real estate objects related to real estate objects subject to appraisal And to support the calculation of the appraisal value.

The appraisal appraisal is a document that requests the appraisal of the appraisal of property or real estate for the analysis of the collateral value, and records the appraisal.

Appraisal means the operation of displaying the economic profit, value and value of an asset in terms of amount. After appraising the collected data and analyzing the factors, the appraisal appraisal should select and apply the appraisal method appropriate to the characteristics of the property or property, the purpose of appraisal and other presented conditions.

Recently, interest in auction related to real estate such as land and buildings has been increasing, and it is true that the real estate processed by the above auction has a great demand for information on the appraisal price not only in the court, financial industry, .

When a client or a financial institution that conventionally evaluates a specific real estate visits the appraisal agency directly to create an appraisal appraisal book and pays the appraisal deposit, the appraisal appraiser of the appraisal appraiser evaluates the property And the appraisal value is calculated and the appraisal report is provided to the client when the appraisal fee is paid in full.

In this case, most of the valuation of real estate through appraisal is judged by taking into consideration various factors such as real estate price, taxation fee, and location of other real estate property adjacent to real estate property subject to appraisal, It is difficult to guarantee the objectivity of the calculated appraisal value due to the subjective opinion involved in appraisal appraisal, and there is a problem that the objective reason for calculating the appraisal value determined is insufficient.

As a result, there is a problem that it is difficult for the majority of the appraisers to evaluate the value of the real estate through appraisal valuation, which may result in disputes or business obstacles.

Therefore, in order to improve the problem of the emotional evaluation process as described above, it is possible to provide objective data that can be accepted by the majority of the emotional evaluation results, while minimizing the influence of the abnormal cases and making a reasonable pricing The development of a system to support the

In order to solve the above problems, a method of evaluating real estate appraisal using the Internet has been proposed in Patent Registration No. 10-0364087.

The method disclosed in the above patent registration No. 10-0364087 is a method for estimating the price of a transaction case land preliminarily stored in each database of a server via the Internet, evaluation prices of an appraisal evaluation institution, It is possible to identify the approximate price level of the real estate, and the client directly assesses the emotion of the real estate directly by the executive program built in the computer, so as to know the estimated value of the appraisal evaluation in advance. Finally, when the appraisal appraisal appraisal is needed, It is possible to reduce the time required for evaluating the emotion and reduce the expense of evaluating the emotion and improve the reliability of the emotion evaluation.

However, the conventional method as described above can only grasp the approximate price level of the real estate to be evaluated, and since it uses only the pre-stored evaluation price, it can not consider the price which changes every moment, and there is a problem in accuracy.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

1 is a conceptual diagram showing a schematic configuration of a system for providing GIS-linked emotion evaluation of the present invention.

Referring to FIG. 1, the system for providing GIS-linked emotion evaluation of the present invention comprises a user 10, a central server 20, and a manager 30.

The user 10 is a user who has an account registered in the GIS linked emotion evaluation providing system or simply wants to utilize the GIS linked feeling evaluation providing system and has the user terminal 11 including the display device and the equipment connectable to the network . The user 10 through the user terminal 11 can access the GIS interoperability emotional evaluation system in the form of a web or an application and can use the contents transmitted to the user terminal 11. [

The central server 20 is a server in which the GIS interoperability assessment evaluation providing system operates and plays the role of operating the entire system between the user 10 and the manager 30 and storing data. Lastly, the manager 30 is an entity that actually operates the GIS linked emotion assessment providing system, and not only provides an emotional evaluation service to the user 10, but also an object to manage the provided data.

FIG. 2 is a block diagram showing a detailed configuration of a GIS inter-working-feeling evaluation providing system according to the present invention, and FIG. 3 is an exemplary initial screen of a GIS inter-working-feeling evaluation providing system.

The GIS interoperability evaluation system includes: an object information providing module (100) for providing object information including a value of a real estate object to be evaluated; (2), which is a real estate item to be compared with the evaluation object (1), in the object information providing module (100), receives the comparison condition with the evaluation object (1) A search execution module 200 for searching for a search result; An emotion evaluation interface 300 for comparing the object information of the evaluation object 1 with the object information of the comparison object 2 to generate association information and deriving a price selection range by performing emotion evaluation based on the association information 300 ); And a display interface (400) for generating and visually representing comparison information in which object information of the comparison object (2) is arranged according to the association information.

First, the object information providing module 100 directly stores and updates object information of a real estate object or receives real estate object information of a real estate object from a plurality of real estate information providers and stores the latest object information at all times The present invention is characterized in that it is possible to provide a basis for comparison in the emotional evaluation since the past transaction examples are stored continuously. In this case, the information of the goods is generally used at the time of sale, the number of floors, apartment house price, exclusive area, land price, sale price, use approval date, use time, official price, use area, utilization situation, traffic situation, , And actual transaction (actual selling price), etc., can be included in the information.

The search execution module 200 receives the comparison condition with the evaluation object 1 which is a real estate object to be evaluated by the user 10 and compares the comparison condition with the evaluation object 1 to be compared with the evaluation object 1 in the object information providing module 100 (2) which is a product. As the comparison condition, parameters for various items related to search of a search radius, a range, a filtering word and the like may be included as well as parameters corresponding to object information for searching for preceding object information. In addition, when the comparison condition is changed, it is possible to perform the search successively even after one data is derived by searching the existing result value or deriving a new result value.

The emotion evaluation interface 300 compares the object information of the evaluation object 1 with the object information of the comparison object 2 to generate association information and performs emotion evaluation based on the association information to determine a price selection range . That is, if any one of the object information of the evaluation object 1 and the corresponding object information of the comparison object 2 are selected and compared, the similarity degree can be determined by the difference value or the like between them, Associated information is generated. The appraisal can be performed on the system through the association information, so that the range of price selection is derived.

Finally, the display interface 400 generates and visually displays the comparison information in which the object information of the comparison object 2 is arranged according to the association information. The visual information provided on the display interface 400 will be described in more detail below.

4 is an exemplary diagram of a report.

The appraisal providing system may further include a report generating module (not shown). The report generating module generates a single file in a report form based on the visual expression derived from the display interface 400 and is shared with the emotional evaluation providing system of the other person. Here, a single file in the form of a report means a file provided in a form of a document through a character and multimedia data such as Hangul / Word / Excel / PowerPoint. A single file in the form of a report can be printed and utilized by the user 10, and has an advantage that it is convenient to share with others.

The emotion evaluation interface 300 will be described in more detail as follows.

(1) and the comparison object (2) based on any one of the above information items except for the address, the lot number, the case type, the number of floors, the use approval date, the exclusive area and the building name, And a comparison evaluating module 310 including an information comparing unit 311 for comparing the information with the reference information.

Except for the price, the physical information of the building, such as address, lot number, case type, number of floors, use approval date, private area, and building name, remains. Therefore, it is needless to say that the land use right, use time, use area, utilization situation, traffic situation, shape, topography and structure explained in the preceding article information can be further utilized. The comparison evaluation module 310 includes an information comparison unit 311 that compares the comparison object 2 and the evaluation object 1 based on the object information to derive the association information and compares and determines the physical characteristics In order to perform the comparison.

Therefore, the emotion evaluation interface 300 uses the information of the object to be evaluated, and compares the information of the object information of the object of comparison (2), excluding the price, with the object information of the evaluation object (1) And a comparison evaluation module 310 including an information comparison unit 311 for comparing and determining the comparison result.

That is, the information comparison unit 311 compares the comparison object 2 with the evaluation object 1 based on the information excluding the price, derives the association information, and compares and determines the comparison information. For example, If the dedicated area is 100 square meters and the exclusive area of the comparison object 2 is 90 square meters, the two are compared and the conclusion that the exclusive area of the evaluation object 1 is larger than the comparison object 2 by 10 square meters is derived .

Also, the emotion evaluation interface 300 may include a price comparison module 340 for deriving price comparison information by comparing the price of the object information of the comparison object 2 with the price of the evaluation object 1, The similarity ranking of the comparison object 2 is determined by comparing the association information and the price association information derived from the comparison evaluation module 310 and the price comparison module 340 with the object information of the evaluation object 1 And a ranking module 350. The ranking module 350 may include a ranking module.

Although the prior information comparing unit 311 compares the object information excluding the price, the ranking module 350 compares only the price, and when the price of the comparison object 2 is compared with the price of the evaluation object 1, The price-related information is derived so as to judge whether or not there is a difference, and the comparative judgment is made. The derived information and the price-related information thus derived are compared again with the object information of the evaluation object 1, and the sum, difference or average of the values derived for each of the comparison objects 2 is selected as the degree of similarity , And the ranking is determined according to the degree of similarity.

The emotion evaluation interface 300 may further include a superiority determination module 320 for comparing the association information and determining the comparison object 2 as a superior or inferior one according to a predetermined criterion. If the related information through the simple comparison is derived in the preceding information comparing unit 311, the related information determining unit 320 rearranges the related information to determine the superiority or the inferiority. (1) If the value of the object information is higher than that of the evaluation object (1), the object (1) of the evaluation object (1) If it is lower, it means that it is expressed by the heat.

 In addition, the object information includes a price including one of a price, a reference price, and an official price, and the comparison evaluation module 310 compares the comparison object 2 And a price selection module 330 for deriving an area between the price information of the two comparison objects 2 in which the first row crosses first, into the price selection range.

In other words, the price may include the price, the base price, the official price, and in the preceding explanation, the time of sale, the apartment price, the sale price, the apartment price, and the actual transaction price (actual selling price). In the price selection module 330, the comparison objects 2 are listed on the basis of the superiority derived from the superiority determination module 320, the two comparison objects 2 in which the first order intersects with each other are identified, (2) based on the price information of each price information. In other words, the intersection of winship means that the two comparative objects (2) are real estate objects with the features closest to the object of evaluation (1) in the sense of superiority or inferiority respectively. Therefore, the range between the two comparison objects 2 can be derived as the price selection range based on the price of the two comparison objects 2.

Herein, the superiority determination module 320 compares the price of the comparison object 2 with the price selection range, and if the difference between the reference price generated in advance according to the predetermined standard and a predetermined range or more occurs, the improper determination And a reservation determination unit 322 for reserving the determination of superiority or inferiority according to a predetermined criterion.

That is, it is not necessary to include the comparison object (2) which has a difference of more than a predetermined level in the comparison evaluation. Accordingly, in the case of the comparison object 2 which is out of the preset reference range (which generally means a difference of 25% or more), it is determined that the comparison object 2 is improper and not displayed, Data can be recognized. Further, the reservation determination unit 322 is configured to display the comparison object 2 to be excluded by the user 10 in a display method that is not used for the display of the superior or inferiority.

The emotion evaluation interface 300 may be configured to calculate the distribution density of the comparison object 2 based on the evaluation object 1 or the distribution density of the comparison object 2 determined to be comparable from the user 10 And a region setting module 360 that can flexibly set a region in which the comparison determination is to be performed.

That is, when the distribution density of the comparison object 2 is greater than or equal to the predetermined range so that the comparison object 2 can be determined to be sufficient, or the region setting module 360 determines that the comparison object 2 It is possible to flexibly vary the region to be subjected to the comparison judgment according to the number of the comparison objects 2, and it is possible to flexibly enlarge or reduce the scope of the actual comparison evaluation through the region setting module 360 .

In this way, we examined the basic structure of GIS interoperability evaluation system. In the following section, we will explain in more detail the method of interworking with GIS, how to perform emotional evaluation, and how to visually express emotional evaluation results in this basic configuration.

FIG. 5 is a diagram illustrating an example in which color setting and indicator are applied, FIG. 6 is an example of confirming indicator duplication, and FIG. 7 is a block diagram illustrating a process of applying transparency in case of indicator duplication.

The display interface 400 may further include a tool providing module 410 configured to display the comparison object 2 in a hue contrast color in accordance with the winning combination of the related information.

(2) can be classified according to the order of related information in the above configuration. At this time, if the colors are compared with each other according to the dominance or the weakness, the user 10 can more easily recognize that the comparison object 2 is classified.

Furthermore, the display interface 400 may further include an indicator designation module 420 for connecting and displaying an indicator including a characteristic of a specific color, thickness, or direction from the comparison object 2.

The indicator is a visual display means, which can be a solid line or a dotted line, and can serve as a kind of leader which can indicate a target or a direction. If such an indicator is connected so as to extend from the evaluation object 1 or the comparison object 2 to a specific position or direction, the visibility is simply increased as compared with the case where the comparison object 2 is colored, There is an advantage that it can be implanted. Also, this indicator may be connected to the evaluation object 1 if necessary, and in this case, one or more comparison objects 2 should necessarily be connected together.

At this time, the indicator designation module 420 measures the intersection angle between the overlapped indicator and the position duplication confirmation unit 421 that detects that the positions of two or more indicators overlap with each other, and gradually increases the transparency value from the indicator having the large intersection angle And a transparency determination unit 422 for controlling the transparency of the indicator so as to be higher.

First, if the color of the indicator is made to have the same color as the color of the comparison object 2, it can have better visibility. In most cases, however, these indicators overlap, making it difficult to distinguish them. That is, when the positions of two or more indicators are overlapped, it is impossible to accurately recognize the progress direction or the connection state of each indicator. Therefore, the intersection angle between the overlapped indicators is measured, and the transparency And the transparency is controlled through the display 422.

That is, by measuring the angle of intersection, it is possible to confirm how much the indicator is open. In the case of a large angle of intersection, it is possible to deduce the progress direction or the connection state of each of the overlapped indicators without particularly controlling the transparency. However, It is advantageous to increase the transparency gradually so that each indicator can be distinguished. Accordingly, the transparency designation unit 422 can be usefully used when there are a large number of indicators in a narrow range or a very large number of indicators toward a specific location.

For example, referring to FIG. 6, a total of six indicators are displayed. If the screen is further enlarged, six indicators are overlapped, and it is difficult to recognize a definite direction. Thus, the intersecting angles a, b, c, d, and e between the respective indicators were obtained. If we compare these crossing angles, we can see that c, e, d, a, and b are in order from the highest crossing angle. Thereafter, one reference indicator for controlling the transparency of the indicator is set. In this example, one indicator will be used as a reference. Thus, the highest order is c, and the corresponding indicator is four. These 4 indicators adjust the transparency to zero. The next intersection angle order is e, which corresponds to indicator 6. Level 6 transparency is assigned to indicator No. 6. The next intersection angle order is d, and the 5th indicator is given a transparency of two steps larger than the first step. By assigning different values of transparency to each indicator in this manner, a large number of indicators can easily identify the direction and connected information even in the overlapping portion.

The tool providing module 410 and the indicator designating module 420 that provide colors and indicators as a tool for visual display of the evaluation object 1 and the comparison object 2 in the display interface 400 have been described. Next, let's take a look at how to use these colors and indicators to visualize actual comparison data.

FIG. 8 is a diagram illustrating an exemplary embodiment of a schematic frame for comparing the top and bottom rows, and FIG. 9 is a block diagram illustrating a process of forming a schematic frame for comparing top and bottom rows.

The display interface 400 includes a comparison object sorting unit 431 for sequentially sorting the comparison objects 2 at positions that are relative to each other based on the winning sequence derived from the winning sequence determination module 320 based on the price selection range, And an indicator application unit (432) configured to combine the indicator extending from the comparison object (2) toward the evaluation object (1) and provide the combined indicator as an evaluation schematic image, .

The graphing module 430 is a module that provides graphical data that can be quickly understood by the user 10 using simple visual elements such as graphs, charts, tables, figures, graphics, and text. In order to provide such data, the comparison object 2 is sequentially listed at a position relative to the superiority derived from the superiority / inferiority determination module 320 on the basis of the price selection range as a preparation for visualization. Through this list, it is possible to identify the comparison object 2 arranged in accordance with the rank of the object 1 to be evaluated.

At this time, an indicator extending from the comparison object 2 toward the evaluation object 1 is further formed. It is possible to quickly recognize whether the comparison object 2 is superior or not through the indicator, 2) It is possible to check at a glance whether the appraisal has been carried out by the value, and which price range has been derived accordingly.

FIG. 10 is an exemplary view illustrating one embodiment of a radiation comparison schematic frame, and FIG. 11 is a block diagram illustrating a process of forming a radiation comparison schematic frame.

The grappling module 430 may further include a comparison target arrangement unit 433 that arranges the arrangement of the comparison targets 2 in the form of a two-dimensional plane, Means that the comparison object 2 is arranged in a radial form in a plane according to the heat of the heat source 320 derived from the heat source.

That is, the comparison target arrangement unit 433 has a field creation part 461 for forming a comparison field in which a main block indicating the evaluation target 1 is located in the central area to which the evaluation schematic image is to be created, A reference placement part 462 which divides the main block into a first area and a second area on the basis of the main block and divides the comparison area 2 into the first area and the second area according to the dominant and inferior areas, And a price spinning arrangement part (463) for rearranging the comparison object (2) in a radial pattern gradually moving away from the main block based on the order, thereby forming a price spinning layout diagram.

In the comparison field, a main block is located at a central portion. The main block is divided into two regions, that is, a first region and a second region with respect to the main block. . At this time, the comparison object 2 is radially arranged in the form of gradually increasing and decreasing gradually in the order of domination or decimation on the basis of the main block, so that the user 10 can recognize the area where the real estate object is located, It is possible to easily grasp the characteristics of the real estate object according to the degree of close proximity to the real estate object.

In addition, the grappling module 430 may further include a volume designation unit 434 for displaying the comparison object 2 as a volume image that increases or contracts in correspondence with the elevation of the degree of similarity. The volume designation unit 434 can display the comparison object 2 in various images such as a circle or a polygon. Further, by increasing or decreasing the size (volume) of each image in correspondence with the degree of similarity, So that the user 10 can utilize the comparison object 2 simply by confirming the volume in which the comparison object 2 is expressed without needing confirmation.

The comparison target arrangement section 433 returns to the comparison target arrangement section 433 and the selection detection section 464 detects that the at least one comparison target 2 is selected by the user 10, A distance determining part 465 for comparing the position information on the map of the object 2 with the position information on the map of the other object 2 to generate the distance information, A distance radiation arrangement part 466 for rearranging the comparison object 2 in a radiation pattern gradually moving away from the distance information to form a distance radiation arrangement diagram, and a distance radiation arrangement part 466 for synthesizing the distance radiation arrangement diagram And a supplementary indicator setting part (461) that forms an auxiliary indicator connecting the same comparison object (2) included in the distance radiation layout diagram from the comparison object (2) included in the price radiation layout diagram And a synthesized evaluation schema generation unit 435 configured by a synthesized evaluation schema generation unit 468.

In other words, it may happen that the user 10 likes one of the displayed real estate objects and wants to confirm the comparison of the real estate objects re-arranged based on the real estate object. In this case, since the evaluation is already performed on the price or the internal structure, it is the result that is listed in the list. In other words, location is very important in real estate, so the best parameter that can be considered as the most commonly considered addition is already the street in the situation where the price and internal composition have already been evaluated. When the user 10 selects one of the comparison objects 2, the user 10 recognizes it and generates the distance information by comparing the position information on the map of the selected comparison object 2 with the position information on the map of another comparison object 2 do. Then, the comparison object 2 is relocated by the newly derived distance information based on the selected comparison object 2 to form a distance radiation layout diagram. The distance radiation layout thus formed is synthesized based on the comparison object 2 selected in the price radiation layout and further includes an auxiliary indicator connecting the same comparison object 2 included in the distance radiation layout diagram and the price radiation layout diagram, So that comparison is possible.

Here, the following equation can be further applied when deriving the separation distance information.

≪

는 선택된 비교대상(2)의 지도상 위치정보이며,

는 비교대상(2)의 지도상 위치정보이고, z는 비교대상(2)의 총 개수를 나타낸다. 즉, 선택된 비교대상(2)의 지도상 위치정보를 기준으로 다른 비교대상(2)과의 절대 거리를 판단하되, 실제 이 절대거리는 길이나 골목 등을 무시한 직선거리이기 때문에, 이에 따른 보정으로서

을 사용한다. 즉, 이 보정값은 선택된 비교대상(2)과 가까울수록 작고, 멀어질수록 큰 값을 갖게 되는데, HPM(Hedonic Price Model)이나 RSP(Repeat Sales Price)등의 부동산가격모형에서도 이와 유사한 방법으로 변수를 설정하여 이 변수를 통해 지수의 오차를 보정함으로써 가치를 평가하는 것으로 알려져있다. 따라서, 이러한 수학식을 통해 실제 도로상황이 어느 정도 고려된 거리의 비교가 가능해지는 것이다.P is the separation distance information,

Is the positional information on the map of the selected comparison object 2,

Is the position information on the map of the comparison object (2), and z represents the total number of the comparison objects (2). That is, the absolute distance to the other object 2 to be compared is determined based on the positional information on the map of the selected object 2. Since the absolute distance is a straight line distance that ignores the distance or the alley,

Lt; / RTI > That is, this correction value becomes smaller as the distance from the selected comparison object 2 is closer to the selected object 2, and becomes larger as it goes farther away. In a real estate price model such as Hedonic Price Model (HPM) or Repeat Sales Price (RSP) It is known that the value is evaluated by correcting the error of the exponent through this variable. Therefore, it is possible to compare distances considering actual road conditions to some extent through these equations.

In addition to this, the evaluation image of the evaluation shows the winning bid statistics (the number of transactions, the appraisal price, the sale price, etc.) of the recent two years of the surrounding main facilities (educational facilities, commercial facilities, traffic facilities, medical facilities, government offices, , The sale rate, the sale rate, etc.) and a schematic image comparing the information. That is, a comparison chart, data, and a schematic image that can be provided through object information can be provided as the evaluation schematic image.

A method of displaying map information by using map information other than the evaluation image may be further considered.

FIG. 12 is an example of applying an isomorphism and a layered image to map information, and FIG. 13 is a block diagram illustrating a process of applying an isomorphism and a layered image.

A position applying unit 441 for generating map generating information by combining positional information on the map of the evaluation object 1 and the object of comparison 2 on a map, And a GIS information display module 440 configured to include a comparison color designator 442 for displaying the color information in a color contrasting with each other.

The map is configured to locate a specific position through coordinate, latitude, or address value. Such map information may be stored in the system itself or received from an external map information provider. The map creation information is generated by synthesizing the position information on the map of the evaluation object 1 and the map of the comparison object 2 on the map, and the color of the comparison object 2 is correlated According to the information, the colors are displayed in contrast to each other, thereby enhancing the visibility.

In addition, the GIS information display module 440 displays a map in which the indicator extended from the position information on the map of the evaluation target 1 to the position information on the map of the comparison object 2 is additionally synthesized and displayed on the map And an indicator application unit 443. That is, on the map, the indicator connected to the comparison object 2 and extended is also displayed on the map, so that it is possible to more easily confirm the separation distance or the like displayed on the actual map.

Further, the GIS information display module 440 includes a level setting unit 444 for classifying the related information into a plurality of levels divided into a predetermined range and giving the level to the comparison object 2 in accordance with the similarity value, And a contour applying section (446) for additionally combining the contour lines on the map and displaying the contour line so as to display the contour lines .

That is, if the module utilizing existing association information is at a level that simply assigns the rank value according to the association information, the level setting unit 444 specifies the level in a certain range using the association information, Target (2) and map. Accordingly, it is possible to classify the comparison object 2 more easily by assigning a certain association information range to the same level.

The isotherms setting section 445 displays the isotherms by grouping a plurality of comparison objects 2 having the same level into one area by using the derived levels. Accordingly, since the real estate objects located in the same isosceles area have similar characteristics, the user 10 can more easily confirm the properties of the real estate objects in the vicinity.

Here, the object information may further include a layer number information, and the classification module may include a layer number information setting unit for providing a layer number image composed of the number of columns corresponding to the total number of layers of the building to which the comparison object (2) 447), a difference value setting unit 448 for extracting a price among the object information corresponding to the number of layers and deriving a difference value from the price of the comparison object 2 and inserting the difference value into a column of the column image corresponding to the number of layers , And the GIS information display module 440 further includes a layer number image application unit 449 for further synthesizing and displaying the layer number image on the map position information on the comparison object 2, .

In the case of multi-storey buildings such as apartment buildings and multi-storey houses, prices are often different for each floor. Further, since the map information is formed in a two-dimensional plane, there is a disadvantage in that it is difficult to know which layer of the real estate object is actually applied to form the isosceles in the expression of the preceding isos. As an arrangement for solving this, there is further provided a layer number image composed of the number of columns corresponding to the total number of layers of the building to which the selection comparison object 2 belongs. That is, if the apartment is composed of fifteen floors, a total of fifteen floors are provided in a vertically or horizontally connected floor image. If the price corresponding to each floor number is extracted and the difference value with the price of the selection comparative object 2 is derived, the number of layers of the real estate object used when creating the canon and the price of the other floor Can be confirmed at the same time.

The display interface 400 includes a GIS information display module 440 that provides map creation information and a graphics module 430 that provides an evaluation schematic image. Therefore, a configuration is also required in which the map information and the evaluation schematic image are controlled to be displayed on the user terminal 11.

FIG. 14 is an exemplary view showing an embodiment in which a display area of a display module is divided, and FIG. 15 is an exemplary view illustrating an embodiment utilizing a display area of the display module.

The display interface 400 further includes a display control module 450 for providing the map creation information and the evaluation schematic image to the user terminal 11 of the user 10 visually . The display control module 450 includes a frame division unit 451 for dividing a display area of the user terminal 11 into a map frame located at an upper portion and a schematic frame located at a lower portion of the map frame, And an image arrangement setting unit 452 for arranging the map creation information in the frame and the evaluation schematic image in the schematic frame, respectively.

The frame division unit 451 divides the display area of the user terminal 11 into upper and lower portions, and designates the upper portion as a map frame and the lower portion as a schematic frame. As can be seen from the name, map creation information is arranged in the map frame and evaluation schematic image is arranged in the schematic frame. When the user 10 confirms the evaluation result through the user terminal 11, So that you can see all the images. Here, the size of the map frame may not necessarily be the same as the size of the schematic frame, and detailed subdivision parts (not shown) may be provided to allow two or more subframes (not shown) to be positioned within a single frame of the map frame or the schematic frame Further, different mapping information or evaluation schematic images may be arranged in each subframe, so that various information derived according to the above-described structure may be included in one screen.

Further, when at least one of the map frame and the graphic frame is selected from the user 10, the display control module 450 displays a pop-up frame for forming a pop-up frame for further displaying the selected frame on the front of the selected frame, And a frame generation unit 453.

That is, as shown in FIG. 12 (a), the user 10 may want to enlarge and view some of the map creation information or the evaluation schematic image. In particular, it is very difficult to visually display all the information on one screen in the case of a large amount of data or a dense real estate information. Accordingly, when one of the frames is selected from the user 10, a pop-up frame for enlarging and displaying the selected frame on the entire surface of the selected frame can be further reduced.

Finally, the object information may further include media information including real photographs and moving pictures of real estate objects. The display module may exclude at least one of the map frame and the graphic frame from the display area An auxiliary frame forming unit 454 for generating an auxiliary frame of the same size in the area of the excluded frame when the control signal for receiving the control signal is received and a media arrangement setting unit 455 ). ≪ / RTI >

That is, as seen from the difference between FIG. 15 (a) and FIG. 15 (b), simply confirming the real estate as a numerical value or a comparison chart is the same as judging only the surrounding explanation without actually tasting the food. Therefore, if you want to check the actual appearance of the real property using the media information included in the information, you can freely display one piece of the two frames and display the media information at the excluded location. It is possible to provide the user 10 with a great convenience by making it possible to confirm the real photographs of the real estate objects.

Through the above configuration, we have examined the configuration and operation of GIS interoperability evaluation system. To summarize, when using this GIS linked emotional evaluation service system, it is possible to confirm goods information easily, so that it is possible to make accurate and quick pricing (appraisal evaluation), and to obtain the result that can be confirmed on one screen and receive report And the user 10 can acquire additional information in real time through the fusion of various information, so that the promptness of evaluation work, cost reduction, and service quality improvement can be brought about.

As described above, the configuration and operation of the system for providing GIS-linked emotional evaluation according to the present invention have been described above and illustrated in the drawings, but the present invention is not limited to the above description and drawings, It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention.
