Elevation information for land
Digital elevation information and digital elevation models for land surface and
surface of inland waters. Simplified or pre-processed data as contours.
Different data for different uses:
- Elevation grid/DEM of low accuracy (ca. 1: 100.000) is needed in Pan-European
analysis
- Elevation grid of high accuracy is needed
Important in modelling of land slides and avalanches, flooding vulnerability,
risk to erosion, flow of water and pollutants, spread of air pollution, fires,
noise, biodiversity. Used in many sectors, amongst others environment, water
supply, energy sector, agricultural and forestry. |

Bathymetry
Digital depth information and digital models. Consists of soundings, gridded
bottom model or other DEMs. Isoline databases should also be available.
Hydrographic surveys in the different countries produces the core data.
Simplified or pre-processed versions with contours from GISCO.
Safety at sea, will anticipated effect of fewer accidents and thereby pollution,
location of valuable biodiversity sites in shallow waters, location of sea
resources and valuable sites for fish farming. Understanding of flow pattern and
chemical composition in water. Also important in assessment of location of
pipelines at sea. |
