Couple of things here Apparently for buffer to work correctly both the source layer and the project must be in the same projection, I tried to buffer a point in EPSG 4325:WGS 84 to a distance of 10 NM (18 520 m since QGIS doesn't support several units) and it didn't work, I can do this with other COTS software The other point is that it would be nice to be able to have multiple buffer rings, just set the number of desired rings and the buffer distance interval (which would be a constant) This is my example I have one airport which I need multiple rings at 10 NM intervals, In QGIS I would need to do 6-10 times a buffer to a different shapefile and then merge them all together. It would be nice to just do it once
