GIS in Archaeology
Geographic Information Systems (GIS) software provides archaeologists with a powerful set of tools for management, analysis and research of cultural resources. The power of GIS lies in the ability to link objects on a map to a database, combining the graphical display of data with database query and analysis functionality. Similar objects are grouped into layers, which can be turned on or off for mapping. The map below has several different layers, with the Alabama State Site File layer on top, then roads, major bodies of water (turned off) and a series of digital topographic maps as a base layer. Using GIS software, we can pan and zoom across the state to a particular area of interest, and identify features on the various map layers. The identify results window displays the attributes for site 1Ca5 stored in the Site File database.
