Boundaries

Boundaries

Completeness checks (r10 and v10) perform a spatial overlay of a checked delivery with a reference area-of-interest (AOI). Each product may have a distinct set of AOI's. Due to license restrictions, AOI boundaries cannot be distributed along with the QC tool. Instead, AOI boundaries shall be distributed as a separate boundary package. The boundary package is a large zip file which will be made available on EEA website for authorized service providers. It must be added to the QC tool by the service provider after installation.

General structure

The boundary package shall be distributed as a zip file with a predefined directory structure. The directory tree is organized by product and AOI.

Boundary for vector products

The file must be supplied in shapefile format and must be named:

boundary_<product>.shp

where:

• product is an identifier of the product, allowed values are:
  • clc for Corine land cover;
  • rpz for Riparian zones;
  • n2k for Natura 2000.

The file must containing polygon features.

The file must have aoi_id attribute. When looking for the boundary the value of particular attribute in the delivery is matched against the value of aoi_id attribute in the boundary file. The particular attribute differ by product:

• clc: country;
• rpz: du_id;
• n2k: id.

Urban atlas products have boundary file included as part of the delivery. So, the v10 completeness check uses such included file and no external boundary file is needed.

Boundary for raster products

The file must be supplied in GeoTiff format and must be named:

mask_<aoi_code>_<product>_<resolution>.tif

where:

• aoi_code is an unique identifier of the AOI and must be always set to eu;
• product is an identifier of the product without resolution suffix, allowed values are:
  • waw for Water and Wetness,
  • default for other products;
• resolution is a resolution of the product; must be set to 020m or 100m.

The file must contain one only raster band, its spatial reference system must be EPSG:3035 and the band must follow the rules:

• the band is of type Byte;
• the NoData property is set to 255.
• the content of the band represents a mask, where following values are allowed:
  • 1 represents cell inside the reference AOI;
  • 255 represents cell outside the reference AOI.

Notes

Some files in the boundary package have legal restrictions (typically national boundary maps).
