Coordinate conversions between geodetic reference frames widely used in Russia
PHOTOMOD GeoCalculator performs coordinate transformations according to Russian State Standard GOST R 51794-2001 and Interstate Standards GOST 32453-2013 (GOST R 51794-2008) and GOST 32453-2017. It implements transformations between Cartesian geocentric and geodetic (latitude, longitude, height above the ellipsoid) reference frames based upon geodetic datums WGS 84, Pulkovo 42, Pulkovo 95, GSK-2011, PZ-90, PZ-90.02, PZ-90.11 and ITRF-2008, as well as projected coordinate systems SK-42, SK-95 and GSK-2011 (based on Gauss-Kruger map projection). In addition some transformations not covered by the standards are supported, namely ones involving WGS 84/UTM reference system and EGM96 geoid model.
Coordinates to be transformed can be typed-in manually, measured in Google Maps or set to the current device location.
