Full Citation Examples
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 7.5-minute by 7.5-minute DSM is comprised of elevations at 5 meter postings. 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.

Abstract: |
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 7.5-minute by 7.5-minute DSM is comprised of elevations at 5 meter postings. 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.

Purpose: |
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 Technologies DEMs, including elevation, hydrography, slope, aspect, and shoreline delineation. |

Lineage
Process Steps
Process Step 1
Description: |
This DEM data product was derived using Intermap Technologies airborne interferometric SAR data acquisition system. The flying height is 32,000 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 bodies of water are assigned an elevation which corresponds to the shoreline. Areas of null data are assigned the value -10000. |
