I think in both France & Spain the cadastral information has been used
largely for mapping buildings and not land-parcels.
In places I know the French cadastral parcel data is difficult to
interpret: overlapping parcels; individual buildings as multiple parcels;
parcel boundaries not according to the location of the little yellow
boundary markers on the ground etc. I presume some of these are artefacts
of how the cadastre is maintained by each commune and subsequent
digitisation. In some cases cadastral parcels do not seem to be
consolidated, so it's impossible to actually derive real property
boundaries without some on-the-ground knowledge.
I'm pushed to think of lots of things I might do with parcel boundaries:
accurate location of urban footpaths is one, nature reserve boundaries
another (either directly or because NE data ceases to be encumbered). I
don't know how much the parcels will accord with things like field
boundaries in rural areas: I'll take a look at the LR Inspire data for S
Derbyshire to get an idea.
