EasyChair Preprint 278

Abstract

Digital elevation model (DEM)  is one of the maps is designed to emphasize the theme of terrain surface level to meet the demands of many fields in our present life. Nowadays, with the development of information technology, geographic information systems (GIS) have been widely used in resource management and the economic and social development issues, has many specialized capable softwares of analyzing space, modeling with high precision interpolation algorithm to support establishing map more quickly and accurately than the previous manual methods. By using the ArcGIS software combined with the capability of processing, interpolating space, research has successfully built a digital elevation model maps for district 8, Ho Chi Minh City at the scale of 1:25000. Results achieved helping users can grasp and evaluate objectively entirely elevation of the terrain surfaces where are flooded in the case study area through the color scale of the elevation; at the same time, shows flooded land surface areas of district 8 is very great when the tide peaked. This is a base for local government who is making and deciding a suitability and long solution to limit the regularly flooding situation in urban area.
