DEBRIS FLOW PREDICTION APPARATUS USING DIGITAL TERRAIN MODEL AND THE PREDICTING METHOD THEREOF

摘要

The present invention relates to a terrestrial-destruction area prediction apparatus and a terrestrial-terrestrial-terrestrial-terrestrial-terrestrial prediction apparatus using a digital terrain model for generating a digital terrain model using topographic map information of a debris flow generating region, As regards the method,The terrestrial current generation region prediction apparatus using the digital terrain model includes a terrestrial digital terrain information DB for storing topographic map information of a region to be analyzed as the terrestrial current generation region prediction basic information; A digital terrain model generation unit for generating a digital terrain model using the terrestrial current generation area prediction basic information of the analysis target area stored in the terrain digital terrain information DB; And a topographic wetness index (TWI), a stream power index (SPI), a slope length (SLI), or two or more of TWI, SPI, and SL using the digital terrain model of the analysis target area generated by the digital terrain model generation unit And a digital terrain model analyzing unit for analyzing at least one of the selected terrain index values by location to calculate the distribution of each of the terrain index values and deriving a terrestrial occurrence prediction area. It is possible to accurately predict the occurrence of the debris flow only by using the area information and the altitude information of the region to be analyzed, thereby remarkably simplifying the arithmetic processing for predicting the occurrence of the debris flow and providing the effect of predicting the occurrence of the debris flow remarkably easily.;
