This week’s topic is projections and how different projections can affect the representation of spatial data. I reprojected a FDGL county boundary shapefile in three projected coordinate systems (Albers, UTM, and State Plane), using Project and Project Raster tools in Esri ArcGIS Pro. To illustrate the differences between projections, the Florida county boundaries are displayed in multiple map views. The table shows the quantified difference in area for four selected counties between the three projections, measured in square miles.
