The DEM products are generated using Intermap's STAR technology (Interferometric Synthetic Aperture Radar). The system is mounted in an aircraft. The Digital Terrain Model (DTM) data product was derived from the Digital Surface Model (DSM) using Intermap's proprietary algorithm. The DTM data for 7.5-minute by 7.5-minute units correspond to the USGS 1:24,000 scale topographic quadrangle map series for areas in the United States and throughout the world. Each tile provides full coverage with overlap into adjacent tiles. Data for locations above 56 degrees North/South are licensed in 7.5-minute by 15-minute tiles.

Title: Data Archive Manager Phone: (303) 708-0955 Email: info@intermap.com The DTMs are used as a fundamental layer of information in Geographic Information Systems (GIS) and Spatial Information Decision Support Systems (DSS). A number of the priority layers of spatial information recognized by the National Spatial Data Infrastructure may be derived from Intermap DEMs, including elevation, hydrography, slope, aspect, and shoreline delineation.

Vertical Positional Accuracy 1 meter RMSE or better in areas of unobstructed flat ground. Completeness Report Coverage maps are provided for each area of acquisition. http://www.intermap.com Conceptual Consistency None This DEM data product was derived using Intermap Technologie's airborne interferometric SAR data acquisition system. The flying height is 29,500 feet Above Mean Sea Level. The primary look direction is West. Areas of missing data are interpolated using continuous curvature spline over non-data areas. Most incidences of non-data areas are due to radar shadow and layover due to steep terrain. Radar shadow is a factor of the local topography. It is often found in mountainous regions and the urban canyons of built-up areas. Occurrences of non-data areas within a DEM are dependent on the look direction of the radar. Significant inland bodies of water are assigned an elevation which corresponds to the shoreline. The ocean area delineated from the Orthorectified RADAR Image (ORI) has been assigned the value -32767. 2006-02-22T00:00:00
