Measure the distance between any number of locations on the map along a custom path. Click to place waypoints, drag markers to fine-tune positions, or click anywhere on the line to insert a new point. Per-segment and cumulative total distances update in real time. All measurements use the Vincenty formula on the WGS84 ellipsoid — the same standard used by GPS systems and professional surveying tools — with sub-millimeter theoretical accuracy.
Click anywhere on the map to place your first waypoint.
Keep clicking to add more waypoints along your path.
Segment distances and the running total update in real time.
Drag any waypoint marker to reposition it after placing.
Click anywhere on the line to insert a new waypoint at that spot.
Click a waypoint in the list to pan the map to that point.
Switch units (km, m, mi, ft, nm) from the unit bar.
Press Ctrl+Z to undo the last waypoint, or Clear to start over.
