There are tools like the one on the Corine Page to remove duplicate nodes before even importing the data. When doing an import, we should fix before importing, not the reverse.

Before we added that bit into Spain, we asked specifically if people were happy about it. The problem is the file we were given was not perfect and had the buffer already included. That would have meant cutting a polygon with the same id. > is anybody now maintaining the data? > The data is being maintained by local contributors. Access to Spot Images and now allowed lots of people to improve the precision of the data of Corine. > i mean, in the center of france there are many changes I think, the farms > the meadow the crops everything is changing . do you think it's a good idea > to import so many things? > Farms, meadows are not changing that much. Towns are expanding, forest expanding or decreasing, etc... but you can only know if you have something in place. CLC was a good starting point for people. I regularly correct my area once I have aerial photography to take into account newer data. The import was decided by the community it was possible to opt out if the people wanted to. We are not tagging the crop so we don't care. It was considered a good idea by the people, and everything that was considered good was imported. The French CLC import took almost 8 months to complete between developping the code, checking Mapnik rendering and so on. Maintenance in general in OSM is an issue whether it is CLC or not. I don't foresee any upgrade to Corine even if we were to get something better considering the correction that many people did. Emilie Laffray
