How this service works
Measures local depression depth for exactly two European coordinates with one method and reports the signed difference and winner where meaningful.
Output
Returns the measured local depression depth values for both input coordinates, the signed numerical difference between them, and an indication of which location is the 'winner' (deeper depression), using a single consistent measurement method across both points.
Example use cases
Site suitability for water retention
“I'm evaluating two potential wetland restoration sites in Germany — one near Hamburg at 53.55 latitude, 10.0 longitude and one near Munich at 48.14 latitude, 11.58 longitude. Compare their local depression depth so I know which naturally holds more water.”
Flood risk comparison for two parcels
“I need to compare flood vulnerability for two land parcels we're considering buying: one in the Netherlands at 52.37 lat, 4.89 lon and one in Belgium at 50.85 lat, 4.35 lon. Which has the deeper local depression and what's the signed difference?”
Agricultural drainage planning
“We have two candidate fields for drainage infrastructure investment in Poland — one at 52.23 lat, 21.01 lon labeled 'Warsaw Field' and one at 50.06 lat, 19.94 lon labeled 'Krakow Field'. Tell me which has the greater depression depth so we can prioritize drainage work.”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/compare-two-depression-depthWhen to prefer
Choose this endpoint when you need a precise, single-method pairwise comparison of local depression depth for exactly two European locations and want a clean signed difference with a declared winner. Prefer it over the multi-site ranking endpoint when you have exactly two points and need direct head-to-head output rather than a ranked list.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will be rejected
- Submitting fewer or more than exactly two location objects causes a validation error
- Missing required latitude or longitude fields returns a schema error
- Network timeout for slow terrain data retrieval
- Identical coordinates may return a zero difference with no clear winner
