How this service works
Combined share of permanent water, herbaceous wetland and mangrove classes. The coordinate is validated against the Natural Earth boundary for Czechia; results outside it are rejected before payment.
Output
A numeric fractional value (0–1 or percentage) representing the combined share of ESA WorldCover 2021 pixels classified as permanent water, herbaceous wetland, or mangrove within the analysis grid around the given coordinate. Coordinates outside Czechia's Natural Earth boundary are rejected before any computation or payment is charged.
Example use cases
Environmental site screening for construction
“We're evaluating a plot near Třeboň at latitude 48.99, longitude 14.77 in the Czech Republic — can you tell me what fraction of the area is classified as water, wetland, or mangrove? We need it for our environmental impact pre-check.”
Flood-risk land characterization
“I'm assessing flood risk for a parcel at latitude 50.08, longitude 14.42 in Czechia. What share of the surrounding land is covered by permanent water or herbaceous wetland according to ESA WorldCover?”
Agriculture suitability analysis
“For the farmland I'm looking at near Olomouc at latitude 49.59, longitude 17.25 in the Czech Republic, how much of the area falls under water or wetland classifications? I want to know before committing to a purchase.”
Technical details
Endpoint
POSThttps://mitteleuropa.halowerk.com/v1/cz-water-wetland-shareWhen to prefer
Choose this endpoint when you need a precise, pixel-level ESA WorldCover 2021 water and wetland fractional share for a specific point location within Czechia. It is ideal for environmental assessments, land-use analysis, flood-risk characterization, or site suitability studies where the combined hydrological land-cover fraction (permanent water + herbaceous wetland + mangrove) is the key metric. Prefer it over generic GIS tools when you need a low-cost, per-call API with built-in boundary validation for the Czech Republic.
Side effects
- Coordinate outside Czechia boundary: request rejected before payment with a validation error
- Latitude or longitude outside European coverage range (34–72.5°N, -31.5–40.5°E): schema validation error
- Missing required latitude or longitude parameters: 400-level error
- Upstream ESA WorldCover data unavailable for the requested pixel: may return null or error response
- Payment failure via x402 protocol: request not processed
