Harris Corporation's very high-resolution, global Digital Elevation Models are, for the first time, now available to commercial users online via the MapMart(r) web portal. The models are generated using a variety of geospatial imagery that is merged and enhanced using an automated, proprietary process developed by Harris. These very accurate, high-quality Digital Elevation Models, or DEMs, provide a foundation for three-dimensional modeling of large geographic areas and have the level of detail needed to identify roadways, rivers, buildings and numerous other features. Companies can use the models to significantly reduce the time and cost associated with dispatching crews to perform early manual surveys of geographic areas or features.

In addition, DEMs are not confined to locations that only can be reached by aircraft, a limitation of traditional models that use laser-based Light Detection and Ranging (LiDAR) technology. Harris processing tools include algorithms for quality control, as well as for interpolating and filling voids where data is not available or the imagery is obstructed. The MapMart division of IntraSearch offers an advanced e-commerce site, enabling users to search and purchase image, elevation, street, and demographic data as well as other geospatial products. MapMart has distribution arrangements for 11 domestic and international commercial satellites. IntraSearch, a Colorado-based corporation since 1951, is a fully integrated professional mapping service and product distribution company with three primary business lines: IntraSearch Mapping, MapMart(r), and SportsMapping(tm).
