Hi,<br><br>in fact CLC data is not so accurate, as the patch size should be at a minimum of 25ha and the segment minimum length of 100m ! it's not bad when looking the data at a small scale, but when using a high zoom level it's not so good ...<br>
<br>May I suggest to use the word "CLC" or "Corinne" in your source tag ? "<span style="white-space:pre-wrap">Készítette a FÖMI a KvVM megbízásából ", even with the use of an automatic translator, it is really not obvious tha</span>t it's related to CLC import !<br>
Don't hesitate also to make a wiki page about Hungary CLC import, and to add oit on the lit (<a href="http://wiki.openstreetmap.org/wiki/WikiProject_Corine_Land_Cover">http://wiki.openstreetmap.org/wiki/WikiProject_Corine_Land_Cover</a>)<br>

More than about one third of Hungary has already been imported from the CLC dataset by others. The following tag is used for attribution:<div><br></div><div>source=<span style="white-space:pre-wrap">© EEA, Koppenhága (2009); Készítette a FÖMI a KvVM megbízásából (2009)</span><br>
<br>I'm not a lawyer but I think this tagging is correct. see <a href="http://lists.openstreetmap.org/pipermail/talk/2011-April/057501.html" target="_blank">http://lists.openstreetmap.org/pipermail/talk/2011-April/057501.html</a></div>
<div><br></div><div>What I do about existing data is: I check all the existing landuse polygons by hand before import. I remove most of the landuse=residential polygons, as they are usually also present in the CLC dataset and the CLC versions are more accurate (checked with Bing). There are also some existing sporadic forests and meadows, but usually they are also represented in CLC so then I delete them and copy the extra information (e.g. name of forest) into the newly imported forest polygon. There were 2-3 cases when CLC and existing data disagreed about a forest, CLC marked it as farm. Then I left both the existing and new data in place and tagged the forests with "fixme=please check this, i don't see any forest here on Bing and CLC marks this as farm, too" or something.<br>
<br>I don't think CLC is low resolution. Vineyards, meadows, forests, etc. are usually accurate. See for example <a href="http://www.openstreetmap.org/?lat=46.3314&lon=19.0919&zoom=13&layers=M" target="_blank">http://www.openstreetmap.org/?lat=46.3314&lon=19.0919&zoom=13&layers=M</a> You can see here that CLC is well-detailed. Nevertheless, there are some voids that need to be filled manually in the future, as you can also see on the linked map fragment.<div class="im">
