What term GIS means? by Chris Rohe

Have you ever heard the term GIS? 
GIS stands for Geographical Information Systems, and what does that mean? 
It’s basically smart maps. Digital maps that have associated data that is open to analysis. When you open a road map on paper, the map reveals a great deal of information but this information is stagnant in that it can’t be queried. 
With GIS we can ask the map questions by querying the databases associated with the map. Every feature or object we see in the GIS map has attributes that are stored in a computer database. The database is information about the features you see on the map. This provides a powerful tool compared to an ordinary map. It allows the GIS user to analyze and create new information about the map they are looking at. 
Hence the term GIS (Geographical Information Systems).
