HRL CLC Backbone 2021: Raster 10m

HRL CLC+ Backbone 2021: Raster 10 m

Pan-European wall-to-wall spatially detailed land cover inventory for the 2021 reference year, for each pixel showing the dominant land cover among the 11 basic land cover classes. The dataset is available as 10 m raster.

The product (Product definition) is composed of exactly one raster:

• CLC+ Backbone 2021 raster product (10m)

The raster could be provided either in one ZIP file or as an s3 delivery in GeoTIFF format.

QC Tool looks into the following checks:

• Raster checks
  • raster.unzip
  • raster.naming
  • raster.inspire
  • raster.attribute
  • raster.epsg
  • raster.pixel_size
  • raster.origin
  • raster.bit_depth
  • raster.compress
  • raster.value
  • raster.gap
  • raster.tile
  • raster.color

Raster checks

raster.unzip

Check description: Delivery file can be unzipped

Required check, the check cannot be skipped.

raster.naming

Check description: Naming is in accord with specification

Required check, the check cannot be skipped.

Naming convention:

• there must be exactly one raster file with .tif filename extension;

• the filename must match regex: ^clms_clcplus_raster_2021_010m_eu_03035_v[0-9]{1}_[0-9]{1};

• letter case is irrelevant;

• example of filename: CLMS_CLCPLUS_RASTER_2021_010m_EU_03035_V01_R00.tif;

raster.inspire

Check description: metadata are in accord with INSPIRE specification.

Optional check, the check may be skipped.

Requirements:

• Each tiff file must contain an INSPIRE compliant XML metadata document;

raster.attribute

Check description: Attribute table is composed of prescribed attributes.

Optional check, the check may be skipped.

Requirements:

The attribute table must always contain the following attributes:

• value, corresponds to unique codes in the GeoTiff file
• count, corresponds to the number of raster cells belonging to each code.
• class_name, a text description of the land use / landcover class corresponding to the code.

raster.epsg

Check description: Raster uses specific EPSG code.

Optional check, the check may be skipped.

Requirements:

• each raster must be assigned spatial reference system EPSG:3035 (ETRS89 ETRS-LAEA equal-area projection);

raster.pixel_size

Check description: Pixel has specific size.

Optional check, the check may be skipped.

Requirements:

• the pixel of all rasters size must be exactly 10m;

raster.origin

Check description: Bounding box upper left corner is positioned on grid.

Optional check, the check may be skipped.

Requirements:

• upper-left X, Y coordinates of the raster must be divisible by 1000 with no remainder;

raster.bit_depth

Check description: Raster datatype is of specific bit depth.

Optional check, the check may be skipped.

Requirements:

• the pixel type must be Byte (8 bits per sample);

raster.compress

Check description: Raster uses specific compression formats.

Optional check, the check may be skipped.

Requirements:

• the tiff files must use LZW compression;

raster.value

Check description: Pixels have specific values.

Optional check, the check may be skipped.

Requirements:

• the values of the pixel must be from the set 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 253, 254.

raster.gap

Check description: There is no gap in the AOI.

Optional check, the check may be skipped.

Requirements:

• there must not be a pixel with value 254 inside AOI;

raster.tile

Check description: The GeoTiff raster file must be tiled.

Optional check, the check may be skipped.

Requirements: The required internal tile dimension is 1024 x 1024 pixels.

raster.color

Check description: Color table is in accord with specification

Optional check, the check may be skipped.

Requirements:

• the color palette must be set to:

• 1: rgb(255, 0, 0);

• 2: rgb(34, 139, 34);

• 3: rgb(128, 255, 0);

• 4: rgb(0, 255, 8);

• 5: rgb(128, 64, 0);

• 6: rgb(204, 242, 77);

• 7: rgb(255, 255, 128);

• 8: rgb(255, 128, 255);

• 9: rgb(191, 191, 191);

• 10: rgb(0, 128, 255);

• 11: rgb(0, 255, 255);

• 253: rgb(191, 223, 255);

• 254: rgb(230, 230, 230);
