Hello, Thank you for your reply. But sorry i do not really understand. Could you make explicit please?
What do you understand by 'geography'? I just make a new test with world mercator & wgs84 also and the result of the buffers are always big circle . So i suppose that the unity is radians/degrés... My raw linear shp is very long. It is a corridor from Berlin to Beijing. According to you, which coordinate system i should select in order to generate a buffer (20kms)? Thank you. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Buffer-with-qgis-wgs84-mercator-world-tp5052504p5052521.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
