Intermap DEMs populate its data store. The DEM products are generated using
Intermap's STAR technology (Interferometric Synthetic Aperture Radar). The system is
mounted in an aircraft.
The Digital Surface Model (DSM) products represent the first reflective
surface as illuminated by the radar. Accuracy statements are based on areas of
moderate terrain. Diminished accuracies are to be expected in areas of extreme
terrain and dense vegetation.
The DSM 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.
The DSMs 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.

The above dates refer to the time of field data acquisition and therefore reflect
ground conditions at that time.

Calculation of the digital elevation model accuracy is described in the
Intermap Technologies Core Product Handbook User's Guide. <URL:http://www.intermap.com/images/handbook/producthandbook.pdf>
Coverage maps are provided for each area of acquisition. <URL:http://www.intermap.com>All data products are 2 meters RMSE or better in areas of unobstructed flat ground.1 meter RMSE or better in areas of unobstructed flat ground.
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.
