“Remote Sensing for the Detection, Monitoring 
and Mitigation of Natural Disasters”

Vienna, Austria 
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 
system. 
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.
