Poly files help

Posted by AE35 on 21 July 2011 in English (English)

Does anyone know a tool who can convert KML with multipolygon borders/admin bounds > to a POLY file on the fly

Well I know I can manuel create them. But I have a batch of 98 KML files which I would like to have as POLY files - because I then can use it in OSMOSIS to cut out only geodata in the polygon(s)

Thanks in advance for your help
