Hi, I need Corine land cover 2006 raster data at 1kmx1km resolution, as accurate as possible. Is it better to start with the 100m raster and resample to 1kmx1km, or use the 250m raster? I cannot find any information on the EEA site about whether the 250m product was created directly from the vector data, or is it already a derived product from the 100m version. And, will it significantly increase accuracy if I start with the vector data and create a 1km raster directly from that? (It will significantly increase the work, so I only want to do this if it significantly increases accuracy). Thanks.

Dear tab,

The CLC raster version are derived from the vector ones.
We rasterize up to 100m as otherwise the raster file on the European window would be huge.
For smaller area of interest a higher resolution is definitely possible. To do so, we would recommend the second approach described in your post.
