Elevation profile
Map & Drawing
Use the pencil tool to draw or edit your path. The profile samples elevations along this polyline.
Notes:
- Distance is geodesic; if DEM is not WGS84, results approximate based on pixel size.
- Sampling spacing applies along the path length; smoothing is a moving average window.
