How this service works
Positive difference between the neighborhood mean and center elevation. The service evaluates a circular 250 metre neighborhood around one coordinate and returns standardized units across all 30 covered countries.
Output
A standardized numeric value representing the positive difference in elevation units between the mean elevation of a 250-metre circular neighborhood and the center coordinate's elevation. A higher value indicates the center point sits in a deeper topographic depression relative to its surroundings. The result is consistent and comparable across all 30 covered European countries.
Example use cases
Flood risk site screening
“I need to know how deep the topographic depression is at coordinates 51.5074° N, 0.1278° W in England — can you get the 250-metre neighborhood depression depth so I can assess flood pooling risk?”
Agricultural drainage assessment
“For a farm plot centered at latitude 47.3769, longitude 8.5417 in Switzerland, what is the terrain depression depth relative to the surrounding 250-metre area? I want to understand if water would pool there.”
Urban infrastructure site evaluation
“We're evaluating a construction site at latitude 52.2297, longitude 21.0122 in Warsaw — can you check how much lower that point sits compared to its 250-metre neighborhood to flag any subsidence or drainage concerns?”
Technical details
Endpoint
POSThttps://euroland.halowerk.com/v1/europe-depression-depth-buffer-250mWhen to prefer
Choose this endpoint when you need a standardized, point-based measure of topographic depression depth at a specific European coordinate using a 250-metre analysis radius. It is preferable over broader DEM queries when you specifically need the neighborhood-mean-minus-center-elevation metric rather than raw elevation, slope, or aspect. Use it for flood risk, drainage planning, agricultural suitability, or environmental assessments across the 30 covered European countries.
Side effects
- Coordinate outside European coverage bounds (latitude 34–72.5, longitude -31.5–40.5) returns an error
- Non-numeric or missing latitude/longitude fields cause a validation error
- Edge cases near coastlines or border regions may return reduced-accuracy values
- Network timeout or service unavailability returns a 5xx error
