Interactive demonstration

Draw the question. Inspect the returned elevations.

Start in Tallahassee, Florida. Choose a point or line tool, draw on the map, then send the generated coordinates to the live Logic Cloud Geo service.

1. Choose geometry

Click the map once to place or replace the point.

Elevation units

Terrain exaggeration 4×

Four times exaggeration makes Florida's low relief easier to see. It changes only the display—not the returned elevations.

Choose a drawing tool and click the map.

Analytical values come from the Logic Cloud Geo USGS 3DEP service. The map's visual 3D terrain uses separate Mapzen terrain tiles and may not match the analytical samples.

How line sampling works

The browser measures the complete multi-vertex line geodesically, selects a readable spacing from 25 meters upward, includes both endpoints, and caps the request at 200 samples. Longer lines are intentionally sampled more sparsely.

What the 3D map means

Tilt, rotation, hillshade, and vertical exaggeration help reveal terrain. They are visualization controls. The numerical table is the service result and remains unchanged when the display exaggeration changes.
