Geodetic Coordinates Converter

The simplest way to convert geodetic coordinates to geocentric and topocentric coordinates — instantly, accurately and 100% offline.

Enter latitude, longitude and height, and convert between geodetic, geocentric (ECEF) and topocentric (ENU) coordinates in every direction. This coordinate converter replaces long manual calculations with a tool built for geodesists, surveyors, engineering and geomatics students, and GIS professionals. No internet connection, no formulas to memorize, no errors.

Features:
• Geodetic ↔ Geocentric (ECEF) conversion, direct and inverse.
• Geodetic ↔ Topocentric (ENU) conversion, direct and inverse.
• Geocentric ↔ Topocentric conversion, direct and inverse.
• Results computed with the geodetic equations used by professionals.
• Clean, fast interface, made for field work and study.
• Works 100% offline, on your device.

Common use cases:
• Fieldwork in surveying and geomatics.
• Student projects in geodesy, geophysics and geography.
• GIS and mapping workflows that need coordinate system conversions.
• Anyone who needs latitude and longitude in another coordinate system.
