HJW COMPLETES NAPA VALLEY, CA COLOR ORTHOPHOTO PROJECT

Oakland, California, June 1, 2005 – HJW GeoSpatial (HJW), Inc., has completed delivery of Napa Valley, CA color orthophotos to a consortium of users.

The Napa Valley project was initiated by HJW to satisfy a demand for high resolution orthophotography of the 468 square-mile region in support of vineyard management and GIS analysis. HJW brought together both public and private entities to form a consortium which would fund the project. This strategy enabled a low cost solution for individual participants, each of which received the full Napa Valley data set. The City of Napa, as well as the County, were strong advocates of the project and worked closely with HJW to implement the funding strategy.

HJW acquired color aerial photography at a scale of 1:15,000 (1”= 1250’), which was scanned at a resolution of 10 microns (2540 dpi), allowing the orthophotos to have a pixel size of 0.5’. To support the production of orthophotos, the digital terrain model was created using LiDAR data which was supplied by Napa County. The orthophotos meet National Map Accuracy Standards for 1”= 200’ scale mapping. As part of the project’s funding strategy, HJW reduced project cost by maintaining rights to resell the data.

Prior to this project, HJW had been providing mapping and orthophotos to the City of Napa since 1997.
