The IUCN Red List of Threatened Species – Spatial Data Download

October 12, 2016

The IUCN Red List of Threatened Species contains assessments for just over 76,000 species, of which about two-thirds have spatial data. This spatial data provided below is for comprehensively assessed taxonomic groups. It is important to note that some species such as those listed as Data Deficient are not mapped and subspecies are mapped within the parental species. The data is available as ESRI shapefiles format and contains the known range of each species. Ranges are depicted as polygons, except for the freshwater HydroSHED tables. The shapefiles contain taxonomic information, distribution status, IUCN Red List category, sources and other details about the maps (see metadata document).

The USGS Land Cover Institute (LCI) – Get Land Cover Data

 The USGS Land Cover Institute (LCI) – Get Land Cover Data

The LCI will address land cover topics from local to global scales, and in both domestic and international settings. The USGS through the Land Cover Institute serves as a facilitator for land cover and land use science, applications, and production functions. The institute assists in the availability and technical support of land cover data sets through increasing public and scientific awareness of the importance of land cover science.

GISCO: Geographical Information and maps – Geodata

October 30, 2014

The geodatafiles presented in this section can be downloaded. To process the downloaded geo-data, the availability of a Geographic Information System (GIS) software is required. Should you look for maps as final product (images) please feel free to browse through the “maps” section.

All datasets are provided with metadata in XML format. An XML style-sheet is also provided to facilitate the metadata visualisation with an HTML browser.

Geographical datasets are provided in two formats: shapefile and ‘personal geodatabase’. Shapefiles have a limitation in the attribute name length. For this reason the attribute name might be truncated when compared to the name found in the metadata or in the personal geodatabase.

GISCO: Geographical Information and maps – Digital Elevation Model (DEM)

GISCO: Geographical Information and maps – Digital Elevation Model (DEM)

A ‘Digital Elevation Model (DEM)’ is a 3D approximation of the terrain’s surface created from elevation data.

The term ‘Digital Surface Model (DSM)’ represents the earth’s surface and includes all objects including e.g. forests, buildings.

The Digital Elevation Model over Europe from the GMES RDA project (EU-DEM) is a Digital Surface Model (DSM) representing the first surface as illuminated by the sensors. EU-DEM covers the 39 member and cooperating countries of EEA and it has been produced by a consortium led by Indra. Intermap edited the EU-DEM and AGI (Aerogeodezijos Institutas) provided the water mask. The EU-DEM dataset is a realisation of the Copernicus programme, managed by the European Commission, DG Enterprise and Industry. The EU-DEM is a 3D raster dataset with elevations captured at 1 arc second postings (2.78E-4 degrees) or about every 30 metre. It is a hybrid product based on SRTM and ASTER GDEM data fused by a weighted averaging approach. The EU-DEM has been generated as a contiguous dataset divided into 1 degree by 1 degree tiles corresponding to the SRTM naming convention. The spatial reference system is geographic, lat/lon with horizontal datum ETRS89, ellipsoid GRS80 and vertical datum EVRS2000 with geoid EGG08. The vertical unit of this DSM is metres. These tiles have then been aggregated into 5°x5° tiles which have been projected to ETRS-LAEA by JRC.

In addition, several products have been generated:

a) a colour shaded relief image over Europe has been created by EEA using a hillshade dataset derived from the ETRS89-LAEA version of EU-DEM (Please note that this dataset cannot be used for analysis purposes and that there are some known artefacts West of Norway.);

b) the hydrography layer (streams, confluence points, and watersheds) and

c) the Root Mean Square Error (denoting the error derived in the quality assessment procedure).

All datasets of Version 1 are made available as tiles (5×5° or 1000x1000km) and as single files:

•EU-DEM in ETRS89 (EPSG code 4258)
•EU-DEM in ETRS89-LAEA (EPSG code 3035)
•Colour shaded relief image over Europe in ETRS89-LAEA (EPSG code 3035)

The datasets are encoded as GeoTIFF with LZW compression (tiles) or DEFLATE compression (European mosaics as single files) for the raster files, and as GDB for the Vector data sets.

The EU-DEM statistical validation documents a relatively unbiased (-0.56 meters) overall vertical accuracy of 2.9 meters RMSE, which is fully within the contractual specification of 7m RMSE. The full report is found here.
