Automated mapping using airborne IFSAR data

Two-antenna interferometric SAR instruments acquire SAR data in such a manner that the signals may be combined and processed to extract the elevation of each pixel. In addition to providing a high resolution topographic map of the area, this allows for geometric rectification and automatic map projection of the SAR image. The interferometric coherence may be used to assist in land-use classification which can further exploited for assisting in automated feature detection and extraction. This paper describes and demonstrates algorithms suitable for automatic generation of map products from Interferometric SAR data.
