Frequently asked questions

Which listed sources support DEM elevation API?

Start with OpenTopography API, Copernicus DEM, USGS 3DEP Elevation (National Map). Choose a DEM by project extent, cell size and access method before calculating slope.

What should I check before using these sources for dem elevation api?

Global products may represent surface features and cannot replace detailed site survey.

How do I inspect OpenTopography API through MCP?

Connect an MCP client to https://terramcp.earth/mcp and call get_source with slug opentopography-api. Review its provenance, access requirements and limitations before contacting the upstream service. Discovery does not make every listed source directly executable through the router.

Are these sources free and independently verified?

Access and licence terms belong to each upstream provider; some products require registration or payment. Open each listing for evidence, health status and enrichment provenance. A wrapper and its underlying API can refer to the same dataset and are not independent observations.
