|Abstract:||We present a novel method that automatically and accurately determines surface elevation in multi-angular WorldView-2 Ortho Ready Product panchromatic images without the need for detailed satellite ephemeris information. The solution expands our work on building height determination using fast template matching on GPUs, which was selected as one of the winners of the 2011 IGARSS Data Fusion Contest. Our method automatically determines parallax in the multi-angular images and derives local object height from it. We first demonstrate results for building heights, which we validate against known building heights acquired from public sources. The trend analysis derived from this is then applied to generate surface elevation for the full scene.|
