Real Estate Portal USA Surpasses 100 Million Vectorized Parcels for National Parcel Layer

CLEVELAND, OH—March 1, 2011—Real Estate Portal USA, a leading  provider in Web-based real estate information for searching and mapping parcels, announced today that its national coverage now includes more than 100 million parcels (property boundaries), encompassing more than 70 percent of the United States population.

The company’s download-ready data—stored in vectorized polygon format rather than point location—is rich with attribution, including assessor parcel number (APN), address, ownership and up to 70 other neighborhood, valuation, land use, and building characteristic attributes as available. The broad coverage of data that Real Estate Portal USA offers enables professionals in any industry to utilize the information on both a regional and national scale.  

Parcel data is becoming increasingly important, as government, utilities, insurance, real estate, appraisal, legal, remote sensing, clean energy, data integration, oil/gas exploration and Web and print mapping industries rely on this type of information for fast and accurate access to land records, associated ownership, land valuation and sales trends. In addition, the vectorized, geo-referenced polygon dataset serves as a detailed and accurate base map for operations and inventory management. Access to extensive data provides entities with a stronger knowledge base, resulting in better business decisions and more cost-effective and profitable operations.

Real Estate Portal USA solves the problems of non-standard parcel data between regions by normalizing parcel attributes to a single naming convention and cleaning and transforming each vector data to utilize a uniform map projection, allowing for seamless integration and interoperability with Web map APIs, including Google and Bing Maps, Google Earth® and standard GIS applications.

Parcel data is accessible for search and browsing through the company’s website ( or by downloading PARLAY (Real Estate Portal USA’s parcel layer for Google Earth®). Through the website, subscribers have instant access to the available United States dataset, which can be downloaded in shapefile, Microsoft® Excel® or KML formats for easy analysis and visualization in GIS, spreadsheet or Google Earth® software.
