How this service works
Cropland-share change 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
A signed numeric value (or structured object) representing the change in cropland share between ESA WorldCover 2020 v100 and 2021 v200 for the 250-metre analysis area centred on the provided coordinate. The result reflects observed map-class change only, not a causal or verified ground-truth finding.
Example use cases
Farm boundary land conversion check
“I need to know whether the area around 51.5° N, 10.2° E in Germany saw any net change in cropland coverage between ESA WorldCover's 2020 and 2021 editions — can you pull that comparison for me?”
Reforestation impact on agricultural land
“We're evaluating a reforestation project near 44.0° N, 12.5° E in Italy — can you tell me how the cropland share changed from 2020 to 2021 for that 250-metre analysis zone so we can see if agricultural land was displaced?”
Agricultural expansion monitoring in Eastern Europe
“Check if there was any cropland expansion between 2020 and 2021 at coordinates 50.1° N, 22.0° E in Poland — I want the ESA WorldCover-based change figure for that spot.”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/worldcover-2020-2021-cropland-changeWhen to prefer
Use this endpoint when you need a fast, low-cost satellite-derived signal of cropland change at a specific European location between the 2020 and 2021 ESA WorldCover releases. It is ideal for agricultural monitoring, land-use auditing, or environmental assessment workflows scoped to Europe. Prefer it over manual GIS workflows or full raster downloads when only point-level change is needed.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) result in an error or empty response
- Invalid or non-numeric latitude/longitude values cause a validation error
- Location falls in an area with no ESA WorldCover data coverage
- Network or payment authorisation failure under x402 protocol
