Design and implementation of GIS data server development for 3D simulation in SAR operation

Abstract

Geographic Information System (GIS) data is needed for modelling earth surface in 3D simulation for SAR operation to make simulation proses as real as possible. Adding integrated GIS data server to simulation sistem make simulation application user does not need to input and prepare the GIS data manually, by reducing simulation application user task, user can more concentrate on simulation proses. In this thesis GIS data server that can provide data needed by the simulation application is designed and implemented by using Web Map Service (WMS) protocol. The designed server needed to able create GIS map from any available format data including already created GIS map from another GIS data server that exist in internet or intranet. The experiment to test server capability and functionality is tested by using several desktop GIS application and virtual globe. The test result show that designed server can function well to serve GIS map to 3D simulation application to create earth surface model. Experiment to test Tile caching and Image Pyramid show that this two methods can really give significant result to improve GIS map loading in 3D simulation application memory system.
