Urban Atlas 2012 Building Heights

Urban Atlas 2012 Building Heights

There is one product layer which can be run through the QC Tool:

Urban Atlas Building Heights: 2012 (Product definition)

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.tile
  • raster.nodata
  • raster.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 one raster file with .tif filename extension;

• the filename must match regex: ^(?P<aoi_code>[a-z0-9]+)_[a-z0-9_]+_ua2012_dhm\\.tif$
  • the name must start with AOI code;
  • the name must contain ua2012_dhm at the end just before the extension;
  • followed by .tif extension;
  • letter case is irrelevant;
  • example of filename: EE003Ly_NARVA_ua2012_dhm.tif;

raster.epsg

Check description: Raster uses specific EPSG code.

Optional check, the check may be skipped.

Requirements:

• the 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 size must be exactly: 10 m

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 1 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 uint16 (value between 0 and 65,535)

raster.compress

Check description: Raster uses specific compression formats.

Optional check, the check may be skipped.

Requirements:

• the tiff file must use LZW compression;

raster.value

Check description: Pixels have specific values.

Optional check, the check may be skipped.

Requirements:

• the value of the pixel must be from the set

*   0 - 1000: Height in metres;
*   65535: NoData;

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 256 x 256 pixels.

raster.nodata

Check description: NoData code is set to the corresponding value.

Optional check, the check may be skipped.

Requirements: NoData value is set to 65535;

raster.inspire

Check description: metadata are in accord with INSPIRE specification.

Optional check, the check may be skipped.

Requirements:

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