Environment, nature and farmland
Greenery, water, natural features, protected areas and farmland, plus environmental indices. The air, noise and heat indices are proxies: they are built from indirect OSM evidence (road density, proximity to industrial land, share of greenery) and are not instrument measurements.
Tools in this group: 20
Air quality (proxy)
air-quality-proxy
A proxy index from road density, proximity to industrial zones and the green buffer. This is an indirect estimate from OSM data, not sensor readings.

No extra parameters — the bounding box is enough for this tool.
Flood risk (estimate)
flood-risk
A basic risk estimate from proximity to water features within buffer_m. It does not replace a hydrological computation or official flood zones.
Calculate right here
Noise exposure (proxy)
noise-exposure
A proxy estimate of noise from proximity to roads, railways and industrial zones. Not an acoustic computation and not sound level meter measurements.

No extra parameters — the bounding box is enough for this tool.
Tree canopy
tree-canopy
Computes tree cover from OSM tree points, tree rows and forest polygons; forest areas are included with the include_forests flag.
Calculate right here
Urban heat island (proxy)
urban-heat
A proxy estimate of overheating: the ratio of greenery to impervious surfaces per grid cell. Satellite land surface temperature is not used here.
Calculate right here
Water bodies and pressure
water-quality
A summary of water bodies: their number, area, connectivity and the surrounding land use as an indirect sign of pressure. No chemical measurements enter the computation.

Cave entrances
cave
Exports the points of cave entrances with the name, elevation and description from OSM tags.

No extra parameters — the bounding box is enough for this tool.
Cliffs and peaks
cliff-peak
Exports cliffs, peaks, saddles and ridges with elevations where the elevation is filled in OSM.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Protected areas
protected-area
Exports protected natural areas classified by type of protection and with the area computed.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Wetlands
wetland
Exports marshes and waterlogged land with the type of wetland and the area.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Coastline
coastline
Computes the length of the coastline inside the bounding box and returns it as separate segments.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Elevation range (estimate)
elevation-proxy
An estimate of the elevation range from contour lines and features carrying the ele tag in OSM itself: minimum, maximum, span, mean. This is not a computation over a DEM — where there are no contours, the estimate is empty.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Dams and weirs
dam-weir
Exports dams and weirs with the height, material and operator from OSM tags.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Springs and wells
spring-well
Exports springs and wells with the drinking water flag where it is filled in.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Landfill sites
landfill
Exports dumps and municipal waste landfills with the operator and the area computed.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Quarries and mines
quarry-mine
Exports quarries and mines with the type of resource extracted and the area.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Allotment gardens
allotment
Exports allotment and vegetable garden plots with the area computed.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Farmland
farmland
Exports agricultural land with the crop, the organic farming flag and the area — from OSM tags.
Calculate right here
No extra parameters — the bounding box is enough for this tool.
Greenhouses
greenhouse
Exports greenhouse operations with the crop and the area.

Orchards and vineyards
orchard-vineyard
Exports orchards and vineyards with the species and produce where they are stated, and with the area.

Input, output and limits
The input is a rectangular bounding box in WGS84 plus one of nine data layers; some tools also take a point. The output is GeoJSON, JSON metrics or a GeoTIFF.
| Layer | What it holds |
|---|---|
| buildings | buildings |
| roads | roads and streets |
| poi | points of interest: services, shops, tourism |
| water | water bodies |
| green_areas | green areas: parks, forests, lawns |
| railways | railways |
| boundaries | administrative boundaries |
| landuse | land use |
| waterways | waterways |
Every tool in the section is free. The bounding box may cover up to 100 km². Rate limits are 10 requests per minute per tool run and 30 requests per minute for reading the catalogue. Without signing in you get up to 10 successful calculations a day; after that the service asks you to register and answers 402 with the code login_required. A box larger than the allowed area is also 402, and an unknown tool id is 404.
