ERWIN HERMAWAN G051060011 ITM-524 ADVANCED GIS 3D ANALYST APPLICATION “ FIND THE VOLUME OF WATER IN JATILUHUR RESERVOIR” Graduate Program Master of science in information technology For natural resource management SEAMEO BIOTROP Bogor Agricultural University 2007

WHY USING 3D ANALYST Makes spatial data look like the world it represent. Seeing the spatial data in three dimensional perspective makes it easy to grasp relationship that remain abstract in two dimensions. The 3D Analyst enables to perform a wide range of activities : Create realistic surface models from multiple input sources. Determine height at any location on a surface. Find what is visible from an observation point. Calculate the volumetrik diffrence beetwen two surface. Work with 3D vector features to make realistic models of the 3D world. Visualize the spatial data in 3D.

That's all Thank's for your attention

When compared to planimetric area, surface area gives an idea about surface roughness. The larger the difference beetwen two values, the rougher the surface.
