niche-Vlaanderen: occurrence and vegetation layer

[Dimi Brosens]

It would be nice to indicate what vegetation layer each occurrence was observed in using the sandbox GBIF Vegetation Layer vocabulary: http://rs.gbif.org/sandbox/vocabulary/gbif/vegetation_layer.xml

[Dimi Brosens]

vegetationLayer = CASE LayerCode WHEN 'K' then 'herbaceous'
WHEN 'S' then 'shrub'
WHEN 'M' then 'mosses'
WHEN 'B' then 'tree'
ELSE LayerCode
END

We have the vegetationLayer information in the occurrence extension query.
