About Course


A GIS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information. ArcInfo, our suggested GIS software, is able to link geographic information with descriptive information using geography as the connection between the many data sets. It is important to realize that GIS can do more than make maps, it allows you to calculate the relationships between map features and analyze the different attributes. A GIS can convert existing digital information, which may not yet be in map form, into forms it can recognize and use. For example, digital satellite images can be analyzed to produce a map layer of digital information about geology. And unlike a paper map, a GIS view consists of many data layers revealing an abundance of information.
