GIS could be a very useful tool for decision making, modeling, mapping, monitoring, and managing resources. In a GIS, different types of data could be used together or individually for different purposes. These are questions people ask all the time, and GIS can be the answer. Before a GIS can provide all the answers, different kinds or data have to be collected, which can help people make different decisions. Vector data can be used for networking, such as stream flow or traffic network.
Raster data contain soil or land cover type information.
A TIN contains elevation information. In this project, TMS data were used for land cover classification, two DLGs were used for networking, a DEM was used to obtain elevation and slope information, and a soil grid was used to obtain soil information.
