INSPIRE Coverages Demystified

LC: CORINE Land Cover - Full Color

Use case: Deliver CORINE Land Cover as a map, once GIS-friendly with the original codes and once visualization-friendly where the classification codes are translated into standard colors.
Dataset: ICGC Landcover dataset according to the CORINE land cover classification this legend; coverage created from GeoTIFF and separate XML file with INSPIRE metadata
Service used: OGC WCPS
Notes: WCPS queries like this typically are generated automatically by some client or script (as we have done here), users will not notice them.

But WCPS can do much more, such as colorizing the values:

WCPS query

for $lc in (INSPIRE_LC)
let $lsub := $lc[E(480000:500000), N(4645000:4654000)]

      case $lsub = 121 return { red:204; green:77; blue:242 }
