<P><FONT SIZE=2>Hi<BR>
<BR>
I would create a new field in the attribute table to be filled with the condition. I believe the simplest way is to use a dbf editor (like openoffice spreadsheet or old versions of excel) to create the condition field (same code for shapes to be dissolved). Then I would use the Dissolve tool from fTools plugin on that field.<BR>
<BR>
Hope that it helps.<BR>

Boa sorte,<BR>

<BR>
Hi,<BR>
<BR>
I'm using the shapefile of the GADM database of Global Administrative<BR>
Areas (<A HREF="http://www.gadm.org">http://www.gadm.org</A>), but the subdivisions of some countries<BR>
(such as Spain, Slovenia and others) are too small. In order to get<BR>
divisions that are more evenly sized among all countries, I need to<BR>
dissolve sub-regions to regions, but only within some of the<BR>
countries. Is there a way to use a "conditional dissolve" on only some<BR>
selected countries?<BR>
<BR>
Cheers<BR>
Márcia<BR>
