GET /v1/terrain/elevationOne point
Look up a map click or one known coordinate in meters or international feet.
Logic Cloud Geo terrain service
USGS 3DEP elevation through a small, explicit API.
Supply WGS 84 latitude and longitude. Receive bare-earth elevation with units, source, resolution, provider, and reference metadata kept visible.
Three working patterns
Use the same service from a click, a table, or a transect.
Named latitude and longitude fields remove coordinate-order ambiguity. Ordered keys are preserved through batch processing so results can be joined back to the source table without guessing.
POST /v1/terrain/elevationsOrdered batch
Submit as many as 500 uniquely keyed WGS 84 points in one request.
POST /v1/terrain/elevationsLine profile
Sample an ordered transect, calculate chainage, and chart the returned elevations.
Learn and reuse
Keep every request inspectable.
The public examples expose the same request, validation, batching, and export steps used to exercise the service.
Interactive map
Draw a point or line and review the returned table and topographic profile.
