Projections and Coordinates



The following map was created in an Albers type projection.   Cntbnd Shapefile was added to ArcMap and under the properties for the “Layer” data frame the coordinates was selected, it was then renamed as Albers and new coordinates was added. To Re-Project Datasets the Project Data Management toolbox was selected.  Once this done to complete the process, new sets of parameters were added and data was re-projected and saved as UTM and coordinates NAD_1983_To_HARN_Florida.  

Under “layer” data frame the shapefile UTM was moved to a new data frame to have both in full extent. After doing this, the attribute table for both were edited and a new field was added and named as Area, with this done the area was calculated for both, and then compared to see the difference which was more or less like 10-12 in value.

Lastly, the following counties were added: Alachua, Escambia, Miami-Dade, Polk by creating a query under properties of Albers and UTM. Features and Symbols were added to give the maps meaning. It was then saved and exported as JPG. ;)
