Description

{METHOD to classify damage type Using damage causalITY}

The description below relates to techniques for classifying the types of damage to the natural environment.

The method of classifying the types of damage to the natural environment is based on the classification according to the target of damage, the classification according to the cause of damage, the classification according to the cause and effect of the damage, the classification according to the damage type, the classification according to the type of the ecosystem, and the cause and effect of the damage by the type of the ecosystem. It can be classified in various ways, such as classification according to the level of damage and classification according to the degree of damage.

Sites damaged by natural environments can be divided into 'causes' that cause damage and 'impacts' that affect the environment. There are methods such as 'classification through influence' and 'classification according to natural/artificial damage' depending on the point of view to classify the types of damage causes.

Classification through impact is divided into drip, shipment, and damage type according to area type. Classification according to natural/anthropogenic causes includes cases of damage caused by natural factors such as typhoons, heavy rains, and earthquakes, and cases where damage to the natural environment occurs due to artificial factors acting as the cause of damage.

It provides a method for classifying damaged areas according to natural/man-made causes of damage, where the cause and effect of damage are clearly identified.

A method of classifying damaged land executed on a computer device, the computer device comprising at least one processor configured to execute computer readable instructions contained in a memory, the method comprising: by the at least one processor, land extracting the first damaged land using the cover map; and by the at least one processor, correcting the first damaged area based on the satellite image and classifying the second damaged area.

According to one aspect, in the step of extracting the first damaged land, the change point of the land may be extracted as the first damaged land by overlapping analysis of the land cover map prepared for each year.

According to another aspect, the extracting of the first damaged land includes: classifying the regulated area and the use area according to the land use regulation geographic information using the KLIS information; extracting damaged land corresponding to the minimum area standard from the remaining areas except for the regulation area and the use area among the first damaged areas; excluding the damaged land corresponding to the project site on which the environmental impact assessment was made from among the first damaged land; and overlapping analysis of the first damaged area and the nature conservation area to add a damaged area having connectivity with the nature conservation area.

According to another aspect, the step of classifying the second damaged land may include: using a satellite image on a map published on the Internet, deleting an area corresponding to an existing developed land, not a changed area, from among the first damaged land; and correcting the first damaged area using the satellite image when the shape of the polygon extracted from the first damaged land in the land cover map does not match the satellite image.

According to another aspect, the damaged site classification method manages, by the at least one processor, the damaged site list classified as the second damaged site as a database together with detailed items including the location and damage type for the second damaged site. It may further include the step of

According to embodiments of the present invention, damaged areas can be classified according to natural/artificial damage for which the cause and effect of damage are clear.

The separate computer-readable recording medium may include a computer-readable recording medium such as a floppy drive, a disk, a tape, a DVD/CD-ROM drive, and a memory card. In another embodiment, the software components may be loaded into the memory 110 through the communication interface 130 rather than the computer-readable recording medium. For example, the software components may be loaded into the memory 110 of the computer device 100 based on a computer program installed by files received through the network 160 .

The processor 120 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input/output operations. The instructions may be provided to the processor 120 by the memory 110 or the communication interface 130 . For example, the processor 120 may be configured to execute a received instruction according to a program code stored in a recording device such as the memory 110 .

The communication interface 130 may provide a function for the computer device 100 to communicate with other devices through the network 160 . For example, a request, command, data, file, etc. generated by the processor 120 of the computer device 100 according to a program code stored in a recording device such as the memory 110 is transmitted to the network ( 160) to other devices. Conversely, signals, commands, data, files, etc. from other devices may be received by the computer device 100 through the communication interface 130 of the computer device 100 via the network 160 .

As another example, the input/output interface 140 may be a means for an interface with a device in which functions for input and output are integrated into one, such as a touch screen. The input/output device 150 may be configured as a single device with the computer device 100 .

Also, in other embodiments, the computer device 100 may include fewer or more components than those of FIG. 1 . However, there is no need to clearly show most of the prior art components. For example, the computer device 100 may be implemented to include at least a portion of the above-described input/output device 150 or may further include other components such as a transceiver, a camera, various sensors, and a database.

The present embodiments can be constructed as a DB (database) by extracting the damaged area (damaged area) through analysis using the land cover map.

As a method of classifying the type of damage, the classification method according to natural/artificial damage is used.

In the case of natural factors and natural phenomena acting as the cause of damage, loss of species, introduction of alien (or endangered species), soil erosion (landslide, etc.) caused by rainfall, wind, and gravity, typhoons, floods, etc. There are natural disasters caused by tsunami (landslides, floods, etc.) and changes in the direction of ocean currents.

On the other hand, causes of anthropogenic damage include primary damage such as construction activities carried out by humans, overexploitation of biological resources, and land use change, and secondary damage such as the effects of nonpoint pollution sources. Looking at the damage caused by each cause, the state and military facilities include forest fires, logging, heliport and transmission tower construction, and pollutants generated from military bases due to military activities. Agricultural activities cause damage to ginseng fields, farmland clearing, forest fires, etc., and create agricultural waterways between farmlands or create small rivers with concrete to damage them. Roads and railroads are being damaged by road expansion and pavement, railroads, forest roads, etc., and other damage caused by visitors to tourist destinations, reclamation and reclamation, and damage by other development projects.

Hereinafter, a detailed process for classification of damage types and DB for each type will be described.

Figure 2 shows an example of a method for classifying damaged land in an embodiment of the present invention.

Referring to FIG. 2 , the processor 120 may extract a land change point (hereinafter, referred to as a 'first damaged land') on the land cover map (S110). The processor 120 may extract the first damaged land by overlapping analysis of the land cover map prepared for each year by collecting the middle classification land cover map. The processor 120 may extract an area in which forests, grasslands, wetlands, agricultural areas, etc. are changed to bare ground as the first damaged area when the land cover change is analyzed by overlapping the collected land cover map data for each year.

3 shows a classification table of the land cover map, and FIG. 4 shows a change area (area indicated in red) on the land cover map as a result of the execution of step S110.

Referring back to FIG. 2 , the processor 120 may classify the regulated area and the use area in the KLIS (S120). The processor 120 classifies and extracts land use regulation geographic information (water environment sector, natural environment sector) among the KLIS information. At this time, the water environment section includes water source protection zone, factory establishment restriction zone, and waterside zone, and the natural environment section includes natural park, natural environment, wildlife protection, natural environment conservation area, and ecosystem conservation zone. The processor 120 classifies and extracts a layer name and a code name from among the collected target layers as KLIS information. In this case, if the code name is unclassified or other, it is excluded from the extraction target.

5 shows a district map of a regulated area and/or a use area of an area extracted as a land change point as a result of performing step S120.

Referring back to FIG. 2, the processor 120, as shown in FIG. 6, among the first damaged land extracted in step S110, overlapping analysis of the remaining areas except for the regulated area and the use area classified in step S120. to perform (S130). The processor 120 overlaps and analyzes areas other than the coverage change area and the use area classification within the land use regulated area among the changed bare areas.

6 shows a result of overlapping analysis as a result of performing step S130.

In addition, the processor 120 analyzes and classifies forests, parks, and overlapping areas among designated items on the cadastral map of the first damaged land, and classifies the corresponding areas by overlapping forests (in the case of forests) and voids (in the case of parks). Forest land, bamboo forest, rocky land, gravel land, sandy land, wetland, wasteland, etc., that make up forests and plains, are considered forests, and land equipped with facilities for public health, recreation, and emotional life. In accordance with the Act on Planning and Use of

The processor 120 determines the minimum area standard of the damaged area target area. The processor 120 extracts only damage that is more than 5,000 m2, which is the minimum area standard for the ecosystem conservation cooperation fund return project and the minimum area of the small-scale environmental impact assessment target project (conservation management area) area.

The processor 120 excludes the target area for the environmental impact assessment project among the first damaged areas. By overlapping analysis of the damaged area target area and the environmental impact assessment project site, the damaged area corresponding to the project site for which the environmental impact assessment was performed is excluded. 7 shows that the target area of the environmental impact assessment project site is excluded, and as shown in the figure, the part corresponding to the yellow box is excluded as the area where the damaged area and the environment impact assessment project site overlap.

Referring back to FIG. 2 , the processor 120 extracts damaged land corresponding to a nature conservation area that is concerned about disconnection of connectivity ( S140 ). The processor 120 can extract damaged land across the country through the above-described process (S110 to S130), and furthermore, a wide-area ecological axis, an ecological nature level 1, a land environment evaluation level 1 and 2, a Baekdudaegan protection zone, a vein (150m left and right), it is possible to additionally extract damaged areas in nature conservation areas with connectivity by overlapping analysis of damaged areas classified with nature conservation areas that are concerned about disconnection of connectivity, such as development restricted areas.

8 shows damaged areas in the nature conservation area with connectivity (cases such as Baekdudaegan protected area, vein, development restricted area, etc.) as a result of performing step (S140).

Accordingly, the processor 120 may obtain the derivation result of the first damaged land based on the land cover map in one step. The processor 120 may classify the first damaged land for each geothermal region, and may classify the first damaged land located within the delayed conservation area with connectivity such as a wide ecological axis, a Baekdu-daegan protected area, a vein, and a development restriction area.

Referring back to FIG. 2 , the processor 120 may derive a final damaged area (hereinafter, referred to as a 'second damaged site') through a correction process such as deletion or correction of the first damaged site (S150).

As a result of comparing the result of deriving the first damaged site based on the land cover map in the first step with the recent satellite image, it is not an area that has been changed to bare ground, but a development area such as a residential area and a transportation area, a rocky mountain, a wetland, a riverside, a grassland, etc. There are cases where this is not the case, and it is necessary to secondaryly correct it.

The processor 120 derives and inspects the second damaged site, which is the final damaged site, through a correction operation using a satellite image on a map (for example, Daum Map, Naver Map, etc.) published on the Internet for the first damaged site. .

As an example, the processor 120 may delete an area corresponding to the previously developed land among the first damaged land (S151). For example, the processor 120 is not an area changed to bare among the first damaged areas, but an urbanization/dry area (a residential area (see FIG. 9), an industrial area (see FIG. 10), a traffic area, a culture/sports/resort area) facilities), agricultural areas (paddy fields, fields, etc.), forest areas (rock mountains, broadleaf forests, coniferous forests, mixed forests, etc.), wetlands (coastal wetlands, etc.), water bodies (inland waters, etc.), grasslands (artificial grasslands, natural grasslands, etc.) ), etc., can be deleted.

As another example, the processor 120 may correct the first damaged area using the satellite image ( S152 ). The processor 120 may correct the damaged area when the shape of the polygon extracted as the first damaged area from the land cover map does not match the damaged area of the satellite image. As shown in FIG. 11 , when a polygon represents only a part of a damaged area of a satellite image, the processor 120 may correct it as an actual damaged area.

The processor 120 may acquire the second damaged paper corresponding to the actual damaged area through correction operations S151 to S152 for the first damaged area.

The processor 120 may standardize the classification of the damaged land type by cause based on the result of the current status investigation on the second damaged land for each cause of damage and build a DB of the damaged land based thereon. Investigation of damaged areas is a quantitative (macro) survey that macroscopically investigates the damaged area and the surrounding area, and predicts and standardizes those that may affect the ecological restoration plan through investigation and analysis of the human and social environment around the damaged area. It can be used as a city reference.

The processor 120 may manage the second damaged site list classified into the final damaged site list through DB conversion, and may manage detailed items including the location of the second damaged site and the damage type (cause) together. It is also possible for the processor 120 to classify the second damaged area for each type of damage and manage it as an individual DB.

As such, according to the embodiments of the present invention, damaged areas can be classified according to natural/artificial damage for which the cause and effect of damage can be clearly identified. By identifying damaged areas and types of damage and establishing an evaluation system for damaged areas, it is possible to increase practicality and efficiency by preparing evaluation standards in various fields, such as applying to restoration projects when planning an ecological restoration project.
