| description | In this paper high-resolution DEM generation has been attempted using the Cosmo-skymed data over the New Delhi, India area. The study area is an urban area filled with lots of building and settlement which was helpful to get the stable point in the time series images data. This DEM generation is based on the highly stable permanents scatter candidate (PSC). This PSC was selected on the basis of amplitude stability index which was generated/calculated using the 25 images of the cosmo-skymed acquired over the time. A sufficient number of field GPS data has been used for result validation. Interpolated output DEM at 10-meter resolution has also been compared with the available SRTM and ASTER DEM for further quality estimation. Presented result demonstrate the capabilities of the technique in constructing a high-resolution quality DEM. |
