GIS - Geographic Information Systems - opens
a vast new world of Information gathering. In some ways it represents an
essential new way to visually navigate through
the vast amount of information on the Internet. Sometimes Words get to be a bit too much on the Web and we wish we could "SEE" all this information.

First of all, though, GIS is a Geographic Mapping Tool. Especially combined with GPS.
Let's learn what some of the basic parts of mapping are, starting with latitude & longitude.
