Natural disaster risk assessment system

Abstract

This invention provides a natural disaster risk assessment system, comprising a geocoding module, a potential image acquisition module, and an image analysis module. The geocoding module converts the address of a target object into its coordinates. The potential image acquisition module connects to the geocoding module and is used in a 3D disaster potential map system to capture potential images centered on the target coordinates. Each potential image contains at least one potential area. Each potential area represents at least one disaster potential, and each disaster potential corresponds to at least one potential occurrence factor of a disaster type. The image analysis module connects to the potential image acquisition module and receives the potential images, analyzing the relative relationships between the target coordinates and the potential areas to generate a natural disaster risk level for the target coordinates.
