The subject of the article is investigation of usage of SRTM topographic data for relief correction evaluation for measured gravitational field. Brief review of SRTM, statistical assessment, comparison of accuracy and vertical resolution ability of SRTM and ground geodetic survey have been represented in article. Analysis of possibility to apply SRTM data for relief correction evaluation for different scales of gravitational survey have been given. It has been found that for the plains terrain, with a height difference of not more than 60 m SRTM data can be used to calculate the correction for the relief of middle and far zones.
