Method
Open or drop a GPX, GeoJSON or JSON file. Toggle individual features to compare line length and total polygon area, then export the visible features as GeoJSON. GPX segments remain separate so gaps are not counted as travelled distance. Files are processed locally in your browser, not uploaded to Kalkylkartan.
Example
Open the sample Stockholm route to inspect its length. In a file with several tracks, hide one track and compare the summary before downloading the remaining features.
