How this service works
Dominant class transition measured from ESA WorldCover 2020 v100 and 2021 v200 for the same 250 metre analysis area. The result is observed map-class change, not a causal claim.
Output
The endpoint returns the dominant ESA WorldCover land-cover class recorded for the specified 250-metre cell in both 2020 (v100) and 2021 (v200), along with the observed class transition between the two years. This is a map-class change observation, not a causal explanation.
Example use cases
Urban expansion monitoring in Germany
“I need to check whether the dominant land-cover class shifted at 52.3° N, 13.4° E between the 2020 and 2021 ESA WorldCover maps — I suspect suburban growth around Berlin pushed it from vegetation to built-up land.”
Post-wildfire vegetation loss check
“Can you look up the ESA WorldCover dominant class transition at latitude 38.0, longitude 23.7 in Greece? I want to see if the map class flipped from tree cover to bare or burnt land between 2020 and 2021.”
Agricultural land reclassification audit
“Check the dominant land-cover class for coordinates 47.1 latitude and 16.6 longitude in Austria for both 2020 and 2021 WorldCover — I'm auditing whether any cropland was reclassified to a different category in that period.”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/worldcover-2020-2021-class-transitionWhen to prefer
Choose this endpoint when you need to detect or audit a dominant land-cover class change at a specific European point between the 2020 and 2021 ESA WorldCover releases. It is the right choice when a single-coordinate class-transition lookup is needed rather than tree-cover share, built-up fraction, or other continuous metrics. Prefer it over the sibling comparison endpoints when the question is categorical (what class was it, did it change?) rather than quantitative (by how much?).
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will be rejected with a validation error
- Invalid or missing latitude/longitude values return a 400-level error
- Transient server errors may return 5xx responses; retry with backoff
- Payment failure (x402) results in a 402 response requiring valid USDC payment
- Locations at the boundary of coverage may yield incomplete or null class data
