Data Modifications There were only a few minor changes from the source map. There were two mistagged polygons in Floyd County in the upper northwest corner. The unit was MIs and it was changed to Ml; source code is GA201. There were two Mh units on the map all tagged with the same attributes. However, they are separate units so I had to manually reattribute the two Mh polygons in the northwest corner of the state. The other Mh unit is mostly in the southern part of the state and it is separated by source code GA201. There was one small line that was added to split one polygon into two in order to correct the attribution. It has a source code of GA101.
