<font 16px/inherit;;inherit;;inherit>Spatial data means any data with a direct or indirect reference to a specific location or geographical areafckgL2. Spatial data can be displayed, manipulated and analysed by means of a spatial attribute that denotes a location on or near the surface of the earthfckgL3. Geographic Information Systems (GIS), for their functioning, needs these data in specific formats and data models. The main models used are raster and vector.</font>
<font 16px/inherit;;inherit;;inherit>Raster: rasters are created on the base of grids. Raster grids are conceptually simple structures, comprising square cells with numeric values or classes attached to each cellfckgL4.</font>
<font 16px/inherit;;inherit;;inherit>Vector: whereas feature in the raster grids are identified simply by the row and column position of cells, vector data comprise explicit spatial coordinates of the features that make up objects. Vector data comprise points, lines and area polygonsfckgL5.</font>
<font 16px/inherit;;inherit;;inherit>Spatial datasets are often described with Metadata. Metadata means information describing spatial data sets and spatial data services and making it possible to discover, inventory and use themfckgL6. In the EU framework some legislative actions have been made to establish an Infrastructure for Spatial Information in the European community (INSPIRE)fckgL7.</font>
<font 16px/inherit;;inherit;;inherit>AlpES Spatial Datasets</font>
<font 16px/inherit;;inherit;;inherit>The AlpES project make use of different transnational spatial datasets for the calculation of the ecosystem services indicators. Where possible, these indicators are recalculated for the test regions with national, regional or local datasets with a better spatial resolution.</font>
<font 16px/inherit;;inherit;;inherit>Some of the sources of the AlpES datasets are:</font>
- <font 12.0pt/12;;inherit;;inherit>European environment Agency</font>
- <font 12.0pt/12;;inherit;;inherit>Copernicus European Union Programme</font>
- <font 12.0pt/12;;inherit;;inherit>Joint Research Center of the European Union</font>
- <font 12.0pt/12;;inherit;;inherit>Open Street Maps</font>
- <font 12.0pt/12;;inherit;;inherit>…</font>
<font 16px/inherit;;inherit;;inherit>The spatial data results of the project are made available with the use of the AlpES WebGIS.</font>
