GeoDrafter Measure
Geodesic distance, area and radius measurement, and the size of any line or polygon you click – keep measurements on the map and export them.
Measure distances (with segment lengths), areas (with perimeter) and radius circles on the ellipsoid, whatever the map projection – the same geodesic results as GeoDrafter's web tools (distance calculator, area calculator, radius map). Feature mode measures an existing line or polygon with one click – its length, or its area and perimeter – and Shift+click adds more features to a total. Radius mode draws a true geodesic circle, either dragged with the mouse or from a typed radius such as "5 km" placed with one click. Metric, imperial or fixed units; results can be copied. Finished measurements can be kept on the map in "GeoDrafter distances" / "GeoDrafter areas" layers with their values as attributes or exported to a GeoPackage. Built for QGIS 4 (Qt6), also runs on QGIS 3.40.
