Thanks Ari,<br><br>Travis mailed me the same info.<br>I understand better now. <br>I'm using the data from <a href="http://www.fao.org/geonetwork/srv/en/metadata.show?id=37139&currTab=distribution">http://www.fao.org/geonetwork/srv/en/metadata.show?id=37139&currTab=distribution</a> now to test and it is much more clear.<br>
<br>Here in The Netherlands we mostly have land classification already in vector, that's why I didn't think of that.<br clear="all"><br>Thanks,<br><br>

Am I not understanding the purpose of gdal_polygonize?<br>
Can somebody tell me some real-life use cases when to use this?<br>

Land cover classification rasters can have large areas of the same (integer) value. I've used the GDAL polygonize code for such rasters.<span class="HOEnZb"><font color="#888888"><br>
