How this service works
Ground elevation in feet and meters at a US latitude and longitude from USGS 3DEP, with data-coverage check.
Output
Returns a JSON object containing the input lat/lon, elevation in feet and meters, the USGS data source URL, a coverage verdict (e.g. available/degraded/not available), a human-readable summary, reasons for any degraded or missing coverage, a list of unchecked items, a timestamp (asOf), and a disclaimer about data accuracy.
Example use cases
Pre-construction site elevation check
“Before we start designing, can you pull the USGS ground elevation at lat 37.7749, lon -122.4194? I need it in both feet and meters.”
Flood risk pre-screening for a property
“I'm evaluating a property at lat 29.9511, lon -90.0715 in New Orleans — what's the ground elevation there in feet and meters so I can get a sense of flood exposure?”
Remote sensing data coverage verification
“I need to know if USGS 3DEP elevation data is available and reliable for the coordinate lat 64.2008, lon -153.1686 in Alaska — can you check and tell me the elevation if it exists?”

Endpoint
GEThttps://land-survey.x402tookit.com/elevation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need USGS-authoritative ground elevation at a specific US point, especially when you also need to know whether 3DEP coverage is available and reliable at that location. It is ideal for site-screening workflows, pre-construction assessment, flood risk analysis, or any geospatial pipeline that requires certified elevation in both feet and meters. Prefer this over generic geocoding elevation estimates when regulatory-grade or survey-grade sourcing matters.
Side effects
- Coordinates outside the US or US territories — USGS 3DEP only covers US points, resulting in a null elevation and a coverage failure verdict
- Invalid lat/lon values outside valid ranges cause a 400-class error
- Degraded data flag returned when 3DEP coverage exists but resolution is lower than optimal
- Network or upstream USGS service outage causing a 500-level error or timeout
- Missing required query parameters (lat or lon) returns a validation error
