Why are each NPDP county-wide parcel map database in a world projection, unprojected lat long values?
A wealth of GIS available at a national level is also provided in this same World Projection, making it possible with NPDP data to be unstintingly matched with all USA data available from ESRI either as part of ArcView/ArcInfo/ArcGIS and/or Geography Network. Also, all TIGER street databases are compiled at this projection along with many other data sets of interest to anyone using NPDP at a national level.
