As would be expected, the Projections Part 2 Lab continued to build on the skills learned in the previous lab. The practice exercises preparing for the actual lab project were entertaining, although I will admit to being a bit disappointed that the bald eagle nest data was for Santa Rosa County instead of Escambia County. At some point I had accidentally deleted the coordinates in my handheld GPS unit for the bald eagle nest on the UWF campus. I know that it's in the vicinity of the cross country trails, but with the vegetative growth over the past few years, I can't spot it any more. At least I now know where to locate a source of data for that information!
The final portion of the lab involved the practice of obtaining, defining and projecting datasets. After aerials were loaded into ArcMap and checked against a basemap, vector files were reprojected and added to help identify the subject area. Finally, an Excel document containing data regarding the petroleum storage tank contamination monitoring sites was edited to convert coordinates in DMS format to DD format to keep ArcGIS satisfied. (Surveying and geocaching provided plenty of experience for that exercise.) After all the information was loaded into ArcMap, prettying up the map was all that needed to be done. I decided to run some queries to sort out tanks by current status. I'm happy to report that in the area covered by the Perdido Bay and Fort Barrancas quads, there are no abandoned tanks.

Defining and projecting datasets throughout this lab helped me realize the extensive versatility and applicability of GIS to so many situations. Many potential uses have come to mind already.
