A pan-European geospatial water database exposed as a JSON REST API

A pan-European geospatial water database exposed as a JSON REST API: 700,000-plus named water bodies across 99 countries (lakes, rivers, canals, reservoirs, ponds, streams, harbours, seas) each with a polygon geometry, surface area, perimeter, salinity classification and type; per-water bathymetric depth charts with maximum and mean depth; navigability attributes including CEMT waterway class, bridge vertical clearances, locks, fuel stations, measurement stations and speed limits; EU bathing-water and water-quality assessments per location; a facilities layer of marinas, campings, camper pitches, slipways and fishing shops; and live conditions (water temperature, wave height, current speed and river discharge). Delivered also as an embeddable map widget, a GeoJSON export for government and research use, and a natural-language assistant answering questions over the database.

Dataset card

Type: not stated
Format: JSON via a REST API with polygon geometries in GeoJSON, plus depth-chart layers and an embeddable map widget
Volume: Stated directly on the site: 700,000-plus water bodies across 99 countries, each with polygon geometry, area, perimeter, type and salinity, plus associated bathymetric depth charts, navigability attributes, water-quality records and a separate point-of-interest layer (marinas, campings, slipways, shops, locks, measurement stations). Live conditions add a time series per water refreshed on roughly an hourly cache. This is a genuinely large geospatial corpus — tens of millions of attributed geospatial records once the facilities and quality layers are included, and the API exposes a statistics endpoint with per-country breakdowns.
Users: Low hundreds to low thousands of registered API and subscription accounts (registration exists and is required to obtain an API key and manage projects; the base is developers, tourism operators, municipalities and researchers rather than consumers, since the public map and assistant work without an account)
History: not stated
Update frequency: not stated
Growth: Active — the corpus grows continuously through user polygon submissions routed into a moderation queue, a recently-added natural-language AI water assistant signals ongoing product development, and a published three-tier pricing ladder plus a customer dashboard for key and usage management indicate active commercialisation
Launched: Request further research — the property publishes no founding date or funding record and the operating entity is a partnership with no public filing. Observable signals (an assembled 700,000-water corpus, a mature sibling consumer product, and a recently-added AI assistant) imply several years of build-out with commercial API launch likely in the early-to-mid 2020s; confirm the exact date directly with the operator.
