| Description |
The data model of the EU-Hydro river network consists of seven polygon feature classes, three polyline feature classes and two point feature classes:
- Point feature classes: Culverts and Nodes;
- Line feature classes: Canals, Ditches and River_Net;
- Polygon feature classes: Canals, Ditches, River_Net, InlandWater, Transit, Coastal and RiverBasins.
EU-Hydro river network has been derived from 20 metres resolution imagery. The feature data extraction has been performed by photointerpretation of Very High Resolution Image Data (2011 - 2013), with resolution of 2.5 meters.
Integrated EU-Hydro database (hydrographic and drainage database) is available in geodatabase format and contains:
- hydrographic nodes, lines, and polygons;
- drainage network elements (basins, catchments, drainage lines and nodes);
- dams;
- coastlines and land polygons. |
