Exercise 19 Map

North/South Pole Lambert Projection

GIS 111 - Class Two

In class two we focused on Data Models and ESRI's Data formats. We discussed in depth, Vector vs. Raster, then covered Geodatabase, Shapefile and Coverage formats. In the first lab we setup a geodatabase. Then in the second lab, we jumped ahead and worked with projections and how ArcGIS handles layers with different projections.
