Intermap Technologies today announced it has completed this month the collection of its high resolution 3D digital model of the entire United States (including Hawaii) which represents 3.1 million square miles (more than 8 million km2). To gather this dataset Intermap planes flew a total of 2,530 sorties which equates to 10,324 hours of actual program airtime.
NEXTMap USA includes 3D digital terrain models, digital surface models, contours, 3D road centerline geometries, and other high-resolution geospatial products. Intermap is using a proprietary airborne radar technology called “Interferometric Synthetic Aperture Radar” (IFSAR). The 3D maps are produced by processing this raw radar data.
Intermap is currently processing and editing the collected data of NEXTMap USA to produce geospatial datasets that will be 100% commercially available in early 2010. “More than 48% of the NEXTMap USA data is currently available for immediate purchase”, said the Denver, Colorado-based company.
The data collection of Europe was completed in May 2008 and all of the data, as yet unprocessed, will be on the shelf and available for purchase by the end of next month.
