HRL Small Woody Features 2015: Raster 100m

HRL Small Woody Features 2015: Raster 100 m

Small woody landscape features are important vectors of biodiversity and provide information on fragmentation of habitats with a direct potential for restoration while also providing a link to hazards protection and Green Infrastructure, amongst others.

Wiki pages related to HRL Small Woody Features products are based on the following product documentation / specification: https://land.copernicus.eu/user-corner/technical-library//hrl_lot5_d5-1_product-specification-document_i3-4_public-1.pdf

The product (Product definition) is composed of exactly three rasters:

• Density of small woody features (swf)
• Density of additional woody features (awf)
• Density of small+additional woody features (swfawf)

The three rasters must be provided in one ZIP file in GeoTIFF format.

QC Tool looks into the following checks:

• Raster checks
  • raster.unzip
  • raster.naming
  • raster.epsg
  • raster.pixel_size
  • raster.origin
  • raster.bit_depth
  • raster.compress
  • raster.value
  • raster.gap
  • vector.inspire

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 three raster file with .tif filename extension;
• the filename of SWF raster must match regex: ^swf_2015_100m_(?P<country_code>eu)_03035_v[0-9]{1}_[0-9]{1}.tif$;
  • the name must start with swf_2015_100m_;
  • followed by 2-letter country code, only eu country code is allowed;
  • followed by EPSG code 03035;
  • followed by delivery version e.g. v1_0;
  • followed by .tif extension;
  • letter case is irrelevant;
  • example of filename: swf_2015_100m_eu_03035_v1_1.tif;
• the filename of AWF raster must match regex: ^awf_2015_100m_(?P<country_code>eu)_03035_v[0-9]{1}_[0-9]{1}.tif$;
  • the name must start with awf_2015_100m_;
  • followed by 2-letter country code, only eu country code is allowed;
  • followed by EPSG code 03035;
  • followed by delivery version e.g. v1_0;
  • followed by .tif extension;
  • letter case is irrelevant;
  • example of filename: awf_2015_100m_eu_03035_v1_1.tif;
• the filename of SWF+AWF raster must match regex: ^swfawf_2015_100m_(?P<country_code>eu)_03035_v[0-9]{1}_[0-9]{1}.tif$;
  • the name must start with awf_2015_100m_;
  • followed by 2-letter country code, only eu country code is allowed;
  • followed by EPSG code 03035;
  • followed by delivery version e.g. v1_0;
  • followed by .tif extension;
  • letter case is irrelevant;
  • example of filename: swfawf_2015_100m_eu_03035_v1_1.tif;

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 100m;

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 0-100, 254, 255.

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 255 inside AOI;

vector.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;
