How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The service evaluates a circular 250 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A standardized surface elevation value in metres, derived via bilinear interpolation from the Copernicus DEM GLO-30 dataset, representing the mean terrain height within a 250-metre circular buffer around the submitted coordinate.
Example use cases
Site suitability for solar farm
“I'm evaluating a site for a solar installation near latitude 40.4 longitude -3.7 in Spain — can you tell me the terrain elevation at that point using the 250m Copernicus DEM average?”
Flood risk baseline check
“We need the surface elevation at latitude 52.37 longitude 4.89 in Amsterdam to baseline our flood risk model — can you pull the Copernicus DEM 250m neighborhood value for that coordinate?”
Hiking trail elevation lookup
“What's the elevation at latitude 45.83 longitude 6.86 near Chamonix, France? I want the averaged 250-metre terrain height from the Copernicus DEM.”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-elevation-buffer-250mWhen to prefer
Choose this endpoint when you need a smoothed, neighbourhood-averaged surface elevation for a specific European coordinate, particularly when point-level noise is undesirable and a 250-metre circular buffer average is appropriate. It is ideal for site assessment, environmental modelling, and GIS enrichment workflows covering any of the 30 Copernicus-covered European countries. Prefer this over the 60m buffer variant when broader terrain context is needed rather than hyper-local terrain.
Side effects
- Coordinates outside European coverage (latitude 34–72.5, longitude -31.5–40.5) return an error or out-of-bounds response
- Malformed or missing latitude/longitude values cause a validation error
- Network timeouts or upstream DEM service unavailability may return a 5xx error
- Coordinates over open ocean or beyond land coverage may return null or no-data elevation values
