Georeferencing Rasters


This is a map of the UWF campus with 2 georeferenced aerial photos. The top half is georeferenced with a 1st order polynomial and has an RMS error of 9.775. The bottom portion of the map is georeferenced using a 3rd order polynomial with an RMS error of 2.0183. I had to start over a few times with this lab because I did not realize that I had the first photo selected when I was trying to georeference the second one. Once I realized my selection was wrong the I restarted and finished fairly quickly.
