摘要
The present invention relates to a method for updating a flood inundation map, the step of constructing spatial phase information including basic plan flood level information for a flood inundation map, and when the basic plan flood level information changed from the spatial phase information is input, a displacement vector of a reference point Calculating a plane displacement amount by projecting a reference point displacement amount changed based on the displacement vector as a plane component, calculating displacement values of two reference points using the calculated plane displacement amount, and calculating the calculated displacement value Calculating the amount of variation of each node within the two reference points by using, calculating the variable node coordinates through the calculated variation amount of each node, changing the coordinate value of each node with the calculated node coordinates, and the changed node coordinates It includes the step of updating the flood inundation map by connecting them. According to the present invention, when the amount of flooding due to climate change changes, it is possible to intelligently recycle the river spatial information created when constructing the existing national and local river flood inundation maps.
