Parcels Plus+ - Empower Your Location

06 February 2009, 7:31pm

Tracking down land parcel data is no easy task. If you’ve done it before, then you know the challenges of acquiring parcel data located in the hands of over 3,000 individual counties and often times with no geographic referencing or known positional accuracy. Even after the data has been acquired, it typically requires conversion and standardization to work with your other GIS layers and may be out-of-date.

eMap International is pleased to bring to the geospatial marketplace the most expansive, up-to-date and accurate US land parcel layer ever offered, Parcels Plus+. This constantly expanding dataset has been painstaking gathered from a range of sources including proprietary real estate archives available nowhere else. Every land parcel has been converted to a standardized delivery format and verified against DOQQs to offer a stated accuracy we can stand behind. Parcels Plus+ features never-seen-before parcels which have been hand digitized from paper maps and rescued from digital files with no geographic structure. When it comes to standardization, coverage, accuracy and currency, no other dataset comes close. Parcels Plus+ empowers your location decisions by allowing for timely, informed and repeatable geospatial decisions.
