Mill Valley, CA: Boundary Solutions is pleased to announce that digital parcel map geographic accuracy has significantly improved over the last two years. This finding is based on 808 records in the National ParcelMap Data Portal Metadata Profile database representing 88 million parcels. As can be seen in the accompanying chart, reported map accuracy ratings provided by these 808 data sponsors are trending toward greater accuracy. The total percentage of parcels with 1 to 6 foot accuracy has increased across the board, while the percentages of parcel with an accuracy rating of 10 ft + has significantly decreased since 2005. This is true whether measured in terms of accuracy by total counties or total parcels.
This shift is due to the accuracy of the NPDP updating process, where maps of poor accuracy are continually being updated with more accurate map data.
All in all, these findings clearly show that digital parcel map database managers nationwide are truly working hard to establish and improving the excellence of this vital GIS data layer.
