How this service works
Difference between maximum and minimum sampled surface elevation. The coordinate is validated against the Natural Earth boundary for France; results outside it are rejected before payment.
Output
A numeric value representing the local relief (difference between maximum and minimum sampled surface elevation) at the specified coordinate within France. Coordinates outside the Natural Earth boundary for France are rejected before any charge is applied.
Example use cases
Flood risk terrain screening
“I need to know the local topographic relief at latitude 43.60, longitude 1.44 in France — how much does the elevation vary across that area? I'm assessing whether it's prone to waterlogging.”
Real estate site suitability check
“Can you check the surface elevation range at latitude 48.85, longitude 2.35 in France? I want to know if the terrain is relatively flat before we consider it for a construction project.”
Agricultural land terrain assessment
“What is the local relief — max minus min elevation — at latitude 44.20, longitude 0.62 in France? I'm trying to understand how rugged the terrain is for a vineyard suitability study.”
Technical details
Endpoint
POSThttps://atlantikland.halowerk.com/v1/fr-local-relief?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, per-point local relief metric (elevation range) for a specific coordinate within France, especially for terrain ruggedness screening, site suitability, hydrology, or agricultural assessments. It is pre-validated against France's boundary, so invalid out-of-country requests are rejected without charge. Prefer it over general DEM APIs when you specifically need the France-scoped local relief computation at low cost ($0.003/call).
Side effects
- Coordinate outside France boundary: request rejected before payment, with a boundary validation error
- Latitude or longitude out of the accepted European coverage range (lat 34–72.5, lon -31.5–40.5): validation error
- Malformed or missing coordinate fields: schema validation error
- Service unavailable or upstream elevation data error: 5xx response
