Read full description

Geo Changer converts geographic coordinates and heights in one clear workspace. Enter a position once, then read or copy it in the formats you need for maps, field notes, and technical work. Coordinate formats: • Decimal degrees (DD), degrees and decimal minutes (DDM), and degrees, minutes and seconds (DMS). • Universal Transverse Mercator (UTM) and Military Grid Reference System (MGRS). • WGS 84 geographic coordinates, Earth-centered Earth-fixed (ECEF), and Web Mercator. Edit a coordinate in any of the five map-reference formats and the other formats update together. Adjust displayed precision, copy one reference, share it, or copy all formats at once. Heights with a stated reference: Enter WGS 84 ellipsoidal height or an elevation referenced to EGM2008 or EGM96. Geo Changer converts between these references with bundled geoid grids, so height calculations work offline. View heights in meters, feet, or kilometers. The coordinate inspector also shows geoid undulation and ECEF values. Designed for practical use: The converter keeps your last position for your next session and offers light, dark, and system appearance. Coordinate calculations run on your device, including the bundled geoid models. Geoid-based elevations are model estimates. For survey work, check the required local vertical datum and accuracy before using a converted height.
