How this service works
Measures local depression depth for two to ten named European sites and ranks the observed values with ties preserved.
Output
A ranked list of the submitted named European sites ordered by their measured local depression depth values, with rank positions assigned and ties preserved — allowing direct identification of the deepest and shallowest depressions across the input set.
Example use cases
Agricultural drainage site selection
“I'm evaluating six candidate farm plots in France and Germany for drainage suitability — can you measure and rank them by local depression depth? Coordinates: Bordeaux (44.8378, -0.5792), Lyon (45.7640, 4.8357), Strasbourg (48.5734, 7.7521), Munich (48.1351, 11.5820), Cologne (50.9333, 6.9500), and Frankfurt (50.1109, 8.6821).”
Flood-risk triage across candidate sites
“We're assessing flood risk potential for four sites in the Netherlands and Belgium — rank them by local depression depth so we know which are most at risk. Sites: Amsterdam (52.3676, 4.9041), Rotterdam (51.9244, 4.4777), Brussels (50.8503, 4.3517), and Ghent (51.0543, 3.7174).”
Environmental restoration site prioritization
“Can you rank these seven European wetland restoration candidate sites by depression depth, preserving any ties? Sites: Stockholm (59.3293, 18.0686), Copenhagen (55.6761, 12.5683), Helsinki (60.1699, 24.9384), Oslo (59.9139, 10.7522), Tallinn (59.4370, 24.7536), Riga (56.9496, 24.1052), and Vilnius (54.6872, 25.2797).”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/rank-sites-depression-depthWhen to prefer
Use this endpoint when you need to compare depression depth across more than two European sites simultaneously and want a ranked output with ties preserved. For a simple two-site signed difference, use the sibling two-site depression depth comparison endpoint instead. Choose this ranking endpoint when selecting among multiple candidate land parcels or when a prioritized ordering of sites is needed rather than a pairwise delta.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) result in validation error
- Fewer than 2 or more than 10 locations triggers schema validation failure
- Missing required latitude or longitude fields returns a 400 error
- Site name exceeding 60 characters rejected
- Payment failure or insufficient USDC balance prevents request processing
