Eight countries, one tool

Each country version knows its own coordinate systems, place names and map background.

Coordinate systems of the Nordics and Germany — one table

This table lists the official horizontal and vertical coordinate reference systems — plus the legacy systems still found in older data — for all eight countries covered by koordinat.online, with EPSG codes and the kind of data sources they typically show up in.

Questions and answers

Why do files need to be stamped with a coordinate system?

Coordinates are only unambiguous together with their coordinate reference system — the same numbers point to completely different places in UTM, a national grid, or WGS84. Without the correct CRS label, receiving software has to guess, and data ends up in the sea or metres off. If you are unsure which system a file actually uses, koordinat.online analyses the file and suggests the coordinate system that best fits the data. The result is shown on the map so you can verify the position and change the selection if needed.

How do I check which coordinate system a file uses?

Drag the file into koordinat.online. The tool analyses the file's available information and suggests a likely coordinate system (UTM, SWEREF 99, ETRS89, ISN2016, System 34 and more), and shows the points on a map so you can verify the position visually — before you pass the file on. No account required.

What happens if I pick the wrong coordinate system?

The data still loads — but in the wrong place: in the sea, in another country, or shifted by metres or centimetres depending on the systems confused. This is the most common geodata delivery error. A quick visual check on koordinat.online catches it before delivery.
