Rooted in the science of geography, GIS integrates many types of data. In a GIS the real world is represented by either one of two spatial models, vector-based, or raster-based. The theory behind the spatial movement is to get away from the 3 dimensions, find their position in the 11th dimension, and then calculate the vectors to teleport, moving at a faster than light speed without occupying the space in between the two locations. (Contains 2 figures. management system tools) vendors have already been taking advantage of GIS to view TAM data in addition to purely numerical reporting. Geographical information systems capture, edit, store, manipulate, and analyze a variety of data that are used to create a display such as Internet mapping sites.
