How this service works
Measures built-up share for exactly two European coordinates with one method and reports the signed difference and winner where meaningful.
Output
Returns the built-up land share percentage for each of the two input coordinates, the signed numerical difference between them, and an indication of which location has the higher built-up share (the 'winner'), based on a consistent remote-sensing method applied across European coverage.
Example use cases
Urban vs rural site selection
“I'm evaluating two candidate locations for a logistics hub in Europe — one in the outskirts of Berlin at 52.45, 13.35 and one near Lyon at 45.80, 4.88. Can you compare their built-up land shares and tell me which site sits in a more urbanized area?”
City development level comparison
“Which is more built-up: the city center of Madrid at 40.4168, -3.7038 or Warsaw at 52.2297, 21.0122? Give me the built-up share for each and the difference.”
Environmental impact pre-screening
“We're assessing two plots in Europe for a green infrastructure project — one at 51.50, -0.12 in London and one at 48.20, 16.37 in Vienna. Can you check which location has less built-up surface coverage so we can prioritize the less urbanized one?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/compare-two-built-up-shareWhen to prefer
Use this endpoint when you need a precise, method-consistent pairwise comparison of built-up land share between exactly two European locations. It is purpose-built for two-point comparisons and returns a direct signed difference and winner, making it ideal for site selection, urban analysis, or development assessment workflows where a head-to-head answer is needed. For ranking more than two sites, use the sibling multi-site ranking endpoint instead.
Side effects
- Coordinates outside the European coverage bounding box (lat 34–72.5, lon -31.5–40.5) will be rejected
- Providing fewer or more than exactly two location objects returns a validation error
- Invalid or non-numeric latitude/longitude values cause a bad request error
- Locations that are identical or nearly identical may produce a near-zero difference with no clear winner
- Payment failure or insufficient USDC balance prevents the call from completing
