Geographic Information System (GIS) is emerging as new trends in research due to its applications cover many important aspects of societies such as natural resource management, civil construction, hazard prediction, 3D city simulation, economic policies decision, etc. Recently, these have been some studies about three dimensional GIS systems in WWW environment [1], [21]-[23], [25] in which making these kinds of systems, spatial analysis and 2D GIS data mining are considered the main focuses in the following years. In this paper, we continue these themes and our early works [22], [26] by developing a framework namely JSG for 3D WebGIS applications. In the other words, a know-how process of creating 3D WebGIS systems from GIS data conversion, terrain splitting to application deployment will be presented. An application of this framework in COMGIS project of Bolzano province, Italy will show its efficiency in real situations. |
