[HOT] landuse/cover import in Cameroon?

I'm a bit scared of reverting that too, so I'm passing it on to the Data
Working Group.

@DWG, the request is to revert a landuse import, but the import is quite
big.

The details of how bad it is can be seen here:
http://wiki.openstreetmap.org/wiki/Bad_imports/Cameroun_Ouest_region_landuse_import

I hope you can help with it?

Thanks a lot,
Sander

>> Hi,

>> Yesterday, I stumbled into large changesets (>50K additions)[0] over

>> Inspecting further this looks like landuse/cover data taken from

>>
>> Further, this seems like a group mapping [2].  9 people with changeset

>>
>> Looking into the osm wiki, I didn't see any document about this.  I've

>> I'm posting here since I know we have HOT initiatives in the region
>> (might be related, might be not).  I'm just curious.
