Week 5 -GIS - Projections Part I

This week in Intro to GIS we started learning about map projections, in the first of a two-part section.

This map and areal data on four counties in Florida demonstrate how ArcGIS can be used to transform a spatial dataset from one map projection to another.  The table shows how the apparent square-mile area of the counties changes, depending on the map projection use.  So, it is important to know which map projection to use for the region of interest when making a map.
