BSI to Obtain Change Layer Patent

Mill Valley, CA:  Boundary Solutions, Inc. is pleased to report that it recently received a Notice of Allowance from the US Patent and Trademark Office for its patent application to the “Change Layer”, the patent to publish in a few months.

To produce the change layer, the most recently released parcel map overlay is spatially compared to the previous parcel map overlay. The following parcel polygons in the new parcel map are identified and copied to a new overlay containing only all parcel boundaries:

• Created due to splitting/subdividing an existing parcel.
• Modified due to a size and/or boundary adjustment.
• Created when two or more parcels are joined into a single parcel.

This technique includes software that expedites the updating of the current database with all changes through a parcel merge procedure.

The advantages of change layer include:

• More convenient archiving of multiple years of changes made to a parcel map.
• Elimination of massive uploads and downloads needed in current procedures.
• The ability to work backwards to observe changes over time, a boon to title dispute assessment wherein only the last couple of years of change is available.

Boundary Solutions Inc. is the custodian of the National Parcel Map Data Portal (NPDP™). As of December 2008, a total of 65 million parcels from 600 jurisdictions are normalized and server-ready for download. Regardless of source format, geodataprocessing softwares subject the content to over 30 software driven modifications and metric recordings to assure universal internal consistency of this geoserver-ready content. NPDP™ content is available as downloads from the NPDP FTP site or internet deployed geoservers including ISC ParcelAtlas. In 2006, Boundary Solutions Inc. was awarded U.S. Patent 7,092,957, entitled “Computerized National Online Parcel-level Map Data Portal.” Claims include multi-state search to locate an address by displaying its corresponding digital parcel map boundary. The original provisional patent application filing date is January 18, 2002. Boundary Solutions, BSI, Boundary Solutions logo, National ParcelMap Data Portal, NPDP, and Rooftop Accuracy are trademarks of BSI. All other trademarks and company names mentioned are the property of their respective owners.
