offers a highly efficient service for flood management and self
saving planning after a disaster. Thus, the system offers
functions such as region selection, monitoring data input, flood
model calculation and data calculated from real-time water
levels, GPS data and monitoring data from remote sensing image
Topographic map in background database quickly updating
The background data elements such as rivers, roads and dikes
can be updated rapidly using new aerial photos and SPOT
images based on color topographic map and layouts with
segmentation method, so that updated information can be carried
on the targets.
The dynamic monitoring system of land-use
Land use changes in potential disaster areas can be monitored
using new and old remotely sensed images and slope and aspect
maps obtained from high-accuracy DEM data. Plough-land
classification area that has a slope greater than 25 % can be
made to support engineering planning and plans for returning
plough-land to forest and cropland to lakes and flood discharge
areas within enclosing-dikes.
