Method for calculating flood damage of flooded areas by using aerial laser survey and GIS information

摘要

The present invention relates to a method for quantitatively calculating a flood damage amount during a summer flood area due to heavy rainfall using an airborne laser surveying and a geospatial information system (GIS), and more particularly, Building "in the residential area, which is a flood damage evaluation item that directly affects flood damage using Light Detection And Ranging (FDI) and Multidimensional Flood Damage Assessment (MD-FDA) based on spatial information (GIS) , "Building contents", "farmland", "crops", "vinyl house", "industrial tangible assets" and "industrial inventory assets" in agricultural areas, To calculate the flood damage amount. The present invention proposes an objective methodology for quantitatively evaluating flood damage level in flood damage caused by flood damage caused by heavy rainfall according to climate change, thereby more accurately measuring flood damage amount in residential area, agricultural area, industrial area, It has the effect of establishing flood recovery measures.
