About maps & coordinates
These coordinate converters and map tools help hikers, researchers and developers work with location data. The Coordinate converter switches between decimal degrees and degrees, minutes and seconds. Distance between coordinates measures the surface distance between two points. The Geojson viewer draws GeoJSON features on a map so you can check shapes and properties, and GPX to KML and KML to geojson move tracks and places between GPS devices, Google Earth and web maps.
Check the coordinate order before converting. Many formats list latitude first, but GeoJSON uses longitude first, and a swapped pair puts points in the wrong place. Preview the result in the Geojson viewer before you share it.

Common questions
Are my GPS files uploaded?
No. The Coordinate converter, Geojson viewer, Distance between coordinates, GPX to KML and KML to geojson run in your browser. Your coordinates and files are processed on your device and are not sent to our server.
How is the distance between coordinates calculated?
The tool measures the shortest distance between the two points over the surface of the Earth, also called the geodesic or straight line surface distance. Driving or walking routes are longer because they follow roads and terrain.
Why did my points land in the wrong place?
The most common cause is swapped latitude and longitude. Another is a missing minus sign for southern or western coordinates. Check both values in the Coordinate converter, then preview the result.
