Elevation Profile samples elevation values along a line and renders the cross-section as a chart. Use it to inspect terrain along a road, pipeline, hike, or any custom path. Each sample reports elevation, slope, and distance.
Open the tool
Open the right-hand panel, switch to the Tools tab, and select Elevation Profile.
Inputs
- Line — the path to sample. You can either select a line dataset or draw a line directly on the map by clicking Draw on map.
- Data source — where elevation values come from:
Google Elevation API(default) — global coverage; capped at 500 samples per request.- Any DEM raster in your project — uses your own digital elevation model.
- Number of samples — how many points to sample evenly along the line. Default 100.
Click Run to query the profile.
Reading the result
A summary card appears below the inputs:
- Chart — area chart of elevation versus distance. Hover to see exact elevation, slope, and distance at each sample, and to highlight the corresponding point on the map.
- Stats — total length, minimum, maximum, mean elevation, and total ascent/descent.
Download
Click Download to export the result as:
- CSV — full sample table.
- Image — high-resolution PNG of the chart and stats.
- Dataset — a new point dataset in your project with elevation and slope as attributes.
Limits and notes
- The Google source is rate-limited; queries above 500 samples are rejected.
- For DEM sources, the profile is interpolated from raster cells — accuracy depends on the DEM's resolution.
- Click Reset to clear the chart, drawn line, and selected dataset.
