How this service works
Water and wetland-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
Returns the observed change in water and wetland land-cover share (as a signed numeric value) between ESA WorldCover 2020 v100 and 2021 v200 for the 250-metre area around the provided European coordinate. This is a map-class observation, not a causal interpretation.
Example use cases
Wetland habitat loss assessment
“Check whether the wetland area around latitude 47.6, longitude 16.7 in Austria shrank or grew between the 2020 and 2021 ESA WorldCover snapshots — I need the water and wetland share change for that 250-metre zone.”
Flood-plain monitoring report
“Has the water and wetland coverage at latitude 51.8, longitude 5.1 in the Dutch river delta changed significantly from 2020 to 2021? I'm looking at potential flood-plain shifts using WorldCover map data.”
Environmental due diligence for land parcel
“I need to check the ESA WorldCover water and wetland change for a parcel at latitude 53.4, longitude 9.9 in northern Germany — did the wetland share increase or decrease between 2020 and 2021?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/worldcover-2020-2021-water-wetland-changeWhen to prefer
Use this endpoint when you need a precise, consistent, single-method comparison of water and wetland land-cover share change at a specific European point between 2020 and 2021, sourced from ESA WorldCover. Prefer it over general GIS tools when you want a pay-per-call, lightweight lookup without needing to manage raster data yourself. It is ideal for environmental monitoring, due diligence, or land-change analytics scoped to European geographies.
Side effects
- Coordinates outside European coverage bounds (lat 34–72.5, lon -31.5–40.5) will be rejected
- Non-numeric or missing latitude/longitude values result in validation errors
- No change detected if both years show identical land-cover classification in the area
- Service may return error if the ESA WorldCover tile for the location has missing data
