Abstract

The present invention relates to a regional disaster assessment system using the GIS, and more specifically, to a regional disaster assessment system by using the GIS which makes it possible to provide more objective and useful data for regional assessment by linking a variety of disaster data collected and controlled by each region to GIS information.

Description

[0001] The present invention relates to a GIS (Regional Disaster Assessment System Using GIS)

The present invention relates to an evaluation system for a disaster area using a geographic information system (GIS), and more particularly, to a system for assessing a disaster area in a disaster area, (GIS), which provides more objective and useful data when evaluating the disaster.

Risk refers to the numerical calculation of the probability of damage to people's lives, property, and the environment on the assumption that the severity of the consequences of hazards to people is predictable and clearly identifiable.

Therefore, the risk can be a frequency of occurrence, a location, a spatial area (the ratio of the expected area of disaster damage to the total area of the area), the duration of the disaster, Secondary effects, seasonality, speed of onset, and warning availability.

On the other hand, regional safety assessment is a key factor in establishing disaster prevention plans.

a'Albe (1979) defined the regional safety assessment as "quantitatively and qualitatively assessing the intensity of disaster risk in the region". In the academic definition, regional safety assessment is understood as the same concept as regional risk analysis.

The US Federal Emergency Management Agency (FEMA), for regional safety assessments, "Processes for determining the probability and outcome of disasters (1992)" to provide a basis for determining a series of disaster relief / Is defined as 'a process or method (1997) for assessing the risk associated with a particular hazard in terms of the occurrence, severity and severity of a disaster, the degree of exposure, and the probability and frequency of consequences' .

And to assess the safety of your area, you need to take into account the hazards that may arise in your municipality, the physical, social and economic damages caused by these disaster hazards, vulnerable areas from these disaster hazards, And the damage or cost that can be reduced through business.

The National Disaster Management System (NDMS) has been established and operated in Korea. In the case of foreign countries, there are various disaster prevention countries such as USA, Europe and Japan. Since the disaster management system has been operating since the 1990s, and the disaster management policy has been shifting from disaster prevention to the center of disaster prevention since the 1990s, regional safety assessment has been recognized as a key issue in disaster management.

Particularly in the US, the CRS assessment has been applied to flood insurance since 1990 and the National Disaster Mitigation Act (DMA) passed the National Assessment of Natural Disasters , And a program-oriented system linked to the integrated GIS system.

On the other hand, the regional comprehensive safety management system is required to develop due to the following reasons, and it is possible to reduce the work efficiency due to the lack of standardization of damage data by disaster type, In order to calculate the scale, it is necessary to establish standardized data of the municipal district, disaster data management and disaster history management system are insufficient to cause disaster risk, potential damage and damage data, It is necessary to develop policy development and disaster mitigation abilities by analyzing the ability to cope with damages, to establish a strengthening infrastructure for responsible administration, to use information on disasters among related agencies, and to improve information utilization through poor system connection will be.

If we look at the conditions of collecting disaster data for regional disaster assessment in Korea, we collect the damage data reported for each disaster area in case of disaster, and calculate the sum of loss of facilities or loss of land, And the results were summed up and summed up in amounts so as to create a disaster annual report using a program such as Microsoft Excel (FIGS. 1 and 2).

In addition, comprehensive data of nationwide scale were added to each item on the basis of the annual report prepared by each region, and the damage to the relevant disaster in a specific period was merely presented as a comprehensive damage amount.

Therefore, the comprehensive data could not provide detailed information related to the disaster, evaluation of the impact of the disaster reflecting the characteristics of the area, relevance of the disaster to the damage, and assessment of disaster damage abatement ability in a specific area.

In addition, there is a comprehensive evaluation system for assessing the safety management capability of local governments and there is no objective risk assessment index. Therefore, it is difficult to establish disaster prevention project and response plan considering regional characteristics. Also, There is also a lack of a system to induce efforts to secure safety infrastructure, such as ratio, facility investment, and dividend payout.

Furthermore, it is difficult to obtain persistent objectivity in evaluating disaster disasters by local disaster information obtained through the above-mentioned operations. First, since the evaluation area is determined first and data are collected, If the administrative boundary of the area changes, it is inconvenient to utilize the accumulated data, and the cause of the natural disaster type, the type of human disaster, and the type of social disaster depend on myriad factors, It is difficult to identify the cause of the disaster caused by the lack of data acquisition, storage, standardization and management system. In addition to direct damages to facilities and human life, disaster damage causes damage to local productivity and residence stability, There is no way to estimate these indirect damages.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The present invention uses the above-mentioned prior-art patent No. 0755890 as it is. Therefore, the features of the device configuration described below are all described in the registered patent No. 0755890. [

However, the present invention is characterized in that the additional embodiment portion in which the specific configuration is partially improved in order to achieve the object of the constitution disclosed in the above-mentioned Japanese Patent No. 0755890 is the most important constitutional feature.

Therefore, the device structure, characteristics and operation relationship described below will be incorporated by reference in the above-mentioned Japanese Patent No. 0755890, and the configuration related to the main features of the present invention will be described in detail at the rear end.

3 is a network system configuration diagram according to an embodiment of the present invention. The regional disaster disaster evaluation system using GIAES according to the present invention includes a geographic database server 20 for storing disaster data, a abatement capacity database server 30 for storing disaster damage abatement capacity data, And a safety evaluation server 10 for calculating a local security degree of a predetermined area. The servers may be interconnected by a LAN or WAN.

The disaster data refers to all data related to natural disasters. It includes meteorological data recorded and recorded for each type of disaster such as typhoon / heavy rain / heavy snow, and data on human / material damage of each city / .

At this time, the meteorological data are generally measured and managed by the meteorological office in Korea, and the corresponding data can be obtained from the local meteorological office or the meteorological office in each region. More preferably, it is possible to acquire necessary data by information that is already input and managed as geographic information, even if the meteorological office is not connected to the meteorological station.

The following is the meaning that the data is input and managed as a reference data.

The geographic database server 20 included as a component of the system according to the present invention refers to a part of a database managed by the National Geographic Information System (NGIS), that is, the national geographic information system. NGIS refers to quantification of spatial information by digitizing geospatial information related to the ground and underground of the entire national territory, such as numerical maps, and is used in national policy and administration such as disaster management, It is a system that enables efficient use. Therefore, NGIS has various types of geographical information that are digitized, such as administrative information, administrative information such as administrative district, landslide hazard zone, flood risk zone and other disaster vulnerable zones, physical information such as road, building, port, Distribution, movement, and the like. In addition, the above-described various types of geographical information to be digitized are not limited in their kind and range, and various additional information can be added as needed.

In the case of meteorological data, if the data originally managed by the Korea Meteorological Administration are transformed and generated in accordance with the NGIS standard, it becomes a geographic data managed to be related to other geographical information. Currently, the Ministry of Construction and Transportation (MOCT) in Korea is in charge of preparing a national integrated geographic information database. However, due to the nature of NGIS, the Ministry of Construction and Transportation does not manage all the input and management of information, When GISEAS data of each layer constituting NGIS is generated, the Ministry of Construction and Transportation is managed in a format that is integrated and managed. That is, all the layers are gathered to serve as national geographic information.

The method for acquiring the weather data by the regional safety evaluation system according to the present invention is obtained from the database server of the NGIS on the NGIS or the data which is not reflected in the NGIS by accessing the meteorological office or the local meteorological office You can get the necessary data.

The damage data by the disaster comprising the data on the human / material damages of each city or district constituting a part of the disaster data can also be obtained from the data of Giaez included by the NGIS generation process, The damage data of the local area owned by each local government can be additionally acquired and used. At this time, the weather data and the damage data by the disaster can be easily obtained if there is a data extraction module from a database that can be easily created by a general knowledge and a LAN or WAN network which can connect to and connect to the database.

As described above, the geographical database server 20 is a logical server concept constituting the system according to the present invention. The geographical database server 20 may be physically one or more than one server, ) And the disaster-damage database server 23 of the national city / county district. That is, since NGIS is not a physical but rather a conceptual entity, it is not necessary to store and manage all the information in one physical server if it follows a certain standard. Therefore, the system according to the present invention acquires predetermined data A plurality of physical servers in which the geographical information is stored can be freely interlinked according to the actual situation.

However, as mentioned above, in order to enable the system according to the present invention to exhibit the optimal function, it is most preferable that the acquired data are data stored and managed according to the GIAES standard.

Specific weather data can include wind (typhoon or strong wind), rainfall (flood or torrential rain), snowfall (snow or cold waves) and palaeo (tsunami) Classes may be graded from grade 4 to grade 4, which may be changed for safety assessment purposes. For example, in the case of wind, it can be classified as first class if it is over 33 기준, second class if less than 25-33,, third class if less than 17-25,, and fourth class if less than 17㎧.

The data on human and material damages in each municipal area generated by each type of disaster are data that calculate the damage amount and damage amount due to disasters caused by the disaster type, grade, city, and district in detail.

Herein, the above mentioned personal and material damages include items such as personal injury, victimization, building damage, land and forest loss, destruction of social infrastructure such as railway, road, port, and bridge, and damage to industrial production facilities. In order to evaluate the disaster damage according to the present invention, the conversion to the constant value based on the evaluation year is required to be performed in accordance with the present invention. We will need it again, and we will explain it below.

The above disaster reduction capability data are data on the coping ability possessed in order to alleviate the disaster damage in a specific area, and the disaster prevention structure installed in each area, the inherent disaster prevention capability of the local environment, · Comprehensive data on preparation of disaster prevention planning and preliminary inspections, enhancement of disaster prevention expertise, publicity activities, examples, alarms and response levels, and disaster recovery capabilities. However, the above information is converted using a predetermined diagnosis index for use in the system according to the present invention. The evaluation items and the weight of the abatement ability can be changed according to the intention of the evaluator. However, 1 can be constructed.

As shown in the above table, the diagnostic indicators can be divided into the preventive stage, the contrast stage, the response stage, and the recovery stage. In the case of the stormwater damage management and mitigation section, We investigated the items including prevention of disasters, prevention of domestic flooding disasters, countermeasures against earthquake outflow disaster, countermeasures for steep slope collapse mitigation, management of natural disaster risk zone, small river improvement project, comprehensive flood prevention plan, As for the sector, we measure the extent to which the establishment of a network of related agencies in the field of disaster prevention is being used and implemented. In regards to the preparation and inspection areas, inspection and maintenance of disaster prevention facilities, operation of drainage pumping stations, preparation for strong winds, And the number of items including the disaster prevention specialization , The publicity and publicity of the residents in relation to the flood damage, and the actual situation of the education. In addition, regarding the cases, alarms and countermeasures, the example of the disaster and the alarm system are evaluated, do.

In the field of coastal and cold waves, the actual situation of natural disasters during the winter season, the measures for coastal damages, the measures for stiffness forecasting, the emergency response system, the prevention of snow disaster such as local residents, And the like. The scores evaluated as described above are input for each item and classified and stored in a separate database.

However, it is obvious that the above classification and evaluation items can be adjusted according to the evaluator's interpretation of abatement ability.

The above abatement capability data will be collected and stored through actual and geographic data. In particular, for some materials, due diligence may be the only evaluation method.

However, as shown in the above table, it is possible to distribute the scores based on the standard diagnostic indicators, and such results can be used in the database management system for each region (city district, etc.) To form a reduction capability database server 30 constituting the system according to the present invention. In the future, it will be possible to acquire data on current due diligence systematically quickly and accurately without any extra effort if it is included collectively by expanding NGIS information.

The safety evaluation server 10 collects the above-described data to comprehensively calculate the safety degree of a specific area, displays the result of the calculation on a map, or displays various data in response to a user's request, Lt; / RTI > module. In one embodiment, the safety evaluation server 10 may color-classify the safety level of the corresponding region on a single nationwide map in which the evaluation regions are classified so that the user can compare safety ratings for a plurality of regions (See FIG. 4), the user can view various data used in the evaluation of the safety level of the area from various angles by selecting the area of interest (FIGS. 5 to 8). In addition, the data used to perform the safety assessment, that is, the disaster disaster evaluation, is not limited to the standard giases data stored in the system according to the present invention, but also to the NGIS, the meteorological office, The non-standardized data of the National Emergency Management Agency, the respective departments of the respective municipal districts and other departments (for example, the National Statistical Office, the Forestry Agency, and the Ministry of Agriculture and Forestry) are easily obtained and provided to the user can do.

It is also possible to display not only data specific to a specific region, but also data of regions to be compared at the same time by displaying them in the form of a table. And the form of such a display is the same as illustrated in Figs.

Hereinafter, a process for deriving the regional security by the regional safety assessment system using the geo-essence of the present invention and a method for using the geo-era information in the process will be described.

13 to 16 are flowcharts and related diagrams of a disaster hazard (safety degree) evaluation method according to an embodiment of the present invention.

First, the user selects an area for which a disaster hazard (safety degree) evaluation is desired (see step S101 in FIG. 13 and FIG. 14). The area may be singular or may be a plurality of two or more. These areas are mainly divided around administrative boundaries. Currently, the administrative districts of Korea are divided into 230 municipalities and 2 administrative cities of Jeju Special Self-governing Province. Then, the user selects the reference period of evaluation (see step S103 in Fig. 13 and Fig. 15). Finally, the type of evaluation is selected (see step S105 of FIG. 13 and FIG. 16), and the type may be either of local safety diagnosis, disaster damage scale diagnosis, and disaster damage reduction capability diagnosis. The local safety assessment is a case of wanting to see the comprehensive safety grade of the area, and the diagnosis of disaster damage scale and the diagnosis of disaster damage abatement ability can be selected when it is desired to view the sub- have. However, if the safety evaluation system according to the present invention is used to evaluate the current status of the whole country in the whole country, the above selection procedure may be provided separately from the intention of the user's convenience. May be omitted. The method of selection can be variously changed according to the demand of the user.

When the above selection is completed (in the case of no selection, a pop-up screen may be displayed so that the user can make a selection, or the user may proceed to the next step according to the default selection value) The disaster data and the disaster damage reduction capability data for a certain period of time are acquired and stored (S107). The items of the disaster data and abatement ability data and the acquisition positions are as described above. In this step, the data is obtained from the geographic database server 20 and the abitability database server 30 on the system according to the present invention, and stored in the safety evaluation server 10 as information for evaluating the local safety degree . The safety evaluation server 10 may further include a separate database for storing the stored data.

The data gathered by the above process will be evaluated by the safety evaluation server through the following steps.

First, the number of disasters for each disaster type according to the severity of the disaster type, and the number of disasters for each region are calculated from the acquired disaster data. The disaster types and grades here are as described above. In this case, the probability of occurrence of the disaster according to the wind grade, the rainfall grade, the digging grade, and the snowfall grade can be derived from the above calculation (S201). Likewise, the above data are used to calculate the disaster damage amount by the disaster type, the grade of the disaster type, and the corresponding region (S203). Here, it is preferable that the amount of the damage in the past year of the damage amount is converted into an invariable value based on the evaluation year for more objective safety evaluation (S205). In other words, the amount of past losses is adjusted to the current level, taking into account current and past inflation levels.

Next, based on the above disaster probability and disaster damage data, the average damage amount of each disaster type is calculated by multiplying the average annual disaster damage amount converted into the invariable value by the average annual occurrence probability of each disaster type, The average amount of damage is summed up to calculate the annual average amount of damage due to disaster in each region (S207).

The annual average amount of damages caused by each disaster in each region is converted into a conversion score for grading as follows. That is, the above average annual damage amount is scored through the following equation (average annual damage amount of the region / maximum annual average damage amount) × 1,000, and the score calculated from the above formula is converted into a statistically meaningful value, = normalize (x, mean, stand_dev) to convert the number to a normalized distribution value and then use the normdist (x, mean, standard_dev, cumulative) After conversion, the highest score (1,000 points) is multiplied to derive the integrated disaster damage score where the relative disparity by region is statistically adjusted to the normal distribution. This process is widely used in other fields, so detailed description is omitted. The integrated score of the disaster damage derived as above can be classified into 10 levels as shown in Table 2 below (S209).

Meanwhile, the disaster damage reduction capability data is processed by the safety evaluation server 10 as follows. That is, the abatement ability data collected and stored as described above is calculated as the conversion score for grading in the same manner as the annual average damage amount. First of all, the following formula is used to calculate the total score of the disaster damage abatement ability through the same procedure as the above (total score of each item / total score of the item to be evaluated) × 1,000. And the grade is also given according to the criteria shown in Table 3 (S211).

Based on the disaster damage data and the abatement capacity data of each area calculated as above, a comprehensive regional safety grade is given based on the academic concept of the disaster prevention advanced country. The following safety diagnosis formula, regional safety level = disaster damage / The safety degree is calculated through the disaster damage reduction ability, and the final grade is derived by the matrix as shown in FIG. 17 (S301). However, the final grading in the matrix is not definite, and the individual numerical values can be changed depending on the change in the concept and the standard of safety. However, according to the characteristics of the matrix according to an embodiment of the present invention, the lower the numerical value, the safer the area is from a disaster, and according to the numerical values calculated by the diagnostic formula, Grade.

If the disaster reduction abilities are at the highest level in all disaster damage classes, adjust the grade so that the 1st grade can be obtained in the local safety assessment and adjust the grade for the part considering the relation between disaster damage and disaster damage abatement ability. do.

The regional security rating of the predetermined area calculated through the above process can be displayed to the user in various ways such as an image form on the map, a graph, a table, and the related detailed information of each area can be simultaneously provided (S303).

The present invention includes such technical structures and features as it is, and it is possible to perform real-time automatic measurement for rainfall and snowy areas, particularly by operating a surveying instrument as shown in FIG. 18, The meteorological station database server 21 configured to be able to manage each region through the local server (CT) (Fig. 18) and to collect it in the central server, that is, the disaster damage database server 23, , It is possible to perform real-time countermeasures against regional disaster disasters, especially heavy rains and heavy snow.

To this end, the present invention includes a surveying instrument 100, as in the example of FIG.

The measurement instrument 100 is divided into a rainfall measurement unit 110 and a snowfall measurement unit 120.

At this time, the rainfall gauging unit 110 includes a housing 112 having a cylindrical top open.

The housing 112 is a container for storing water by receiving water during a rainfall, and a scale line L is displayed on a part of the inner circumferential surface at a predetermined interval in the height direction, preferably at intervals of 1 mm.

A plurality of small-sized water sensors S are arranged on each of the scale lines L.

In addition, the funnel 114 is mounted on the upper end of the housing 112 to collect rainwater during rainfall.

Preferably, the funnel 114 is of a simple seating type rather than a fixed type in order to facilitate separation and cleaning.

Particularly, a portion of the outer surface of the funnel 114 is formed with a circumferential 'a' -shaped grooved groove 116. When the housing 112 is seated on the housing 112, the top edge of the housing 112 is fitted, It is more preferable to be constructed so as to be seated.

A control box CB is detachably fixed to one side of the outer circumferential surface of the housing 112. A control part CPU connected to the water detection sensor S and a control part And a communication antenna ANT is provided on the upper surface of the battery BAT.

Thus, the information measured via the antenna (ANT) is transmitted to the rainfall collection area server (CT).

The rainfall collection area server (CT) has a separate management server for each municipality or region, so that statistical statistics for each region can be calculated in real time.

In addition, the rainfall collection area server (CT) is connected to the disaster damage database server (23), and mutual information transmission / reception is maintained. Also, the disaster damage database server (23) So that the regional survey information can be finally collected and managed by the weather station database server 21.

In addition, a pair of fastening bosses (BOS) integrally protrude from one side of the housing 112 at upper and lower intervals, and a fixing bolt BT is detachably fastened to the fastening bosses BOS.

At this time, the fixing bolts BT are vertically penetrated through the snowfall measurement bar 122 constituting the snowfall measurement unit 120.

Here, the fastening bosses (BOS) and the fastening bolts (BT) must be formed as a pair as shown in the drawing, so that the snow measuring bar 122 can be vertically installed without tilting.

Particularly, in order to increase the vertical degree, a pair of spacing bar 118 protrudes between the fastening bosses (BOS) of the outer circumferential surface of the housing 112.

Therefore, if the snow measuring bar 122 is fastened with the fixing bolts BT, the snow measuring bar 122 is vertically erected while maintaining the gap with the housing 112 automatically.

In addition, a plurality of proximity sensors AS are installed in the height measurement direction bar 122, and are preferably spaced apart by 1 mm, and are connected to the control unit (CPU).

As a result, the rainfall or snowfall is immediately detected in real time, the information is collected in the rainfall collection area server (CT), and collected in the disaster damage database server (23) There is an advantage that the measures can be made more quickly.
