Ground Elevation at a U.S. Point (USGS Elevation Point Query Service)

usgsepqs/elevation-at-point

Ground elevation in feet at one U.S. latitude and longitude, from the U.S. Geological Survey Elevation Point Query Service. One point per call. U.S. coverage only. Returns the service's own record: the elevation value, the point echoed back (x is longitude, y is latitude) and the service's raster id and resolution. U.S. Geological Survey data, passed through unmodified and served by Eden Engine; not an official USGS product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "usgsepqs/elevation-at-point" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "usgsepqs/elevation-at-point" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "usgsepqs/elevation-at-point", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "usgsepqs/elevation-at-point", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
