his post has NOT been accepted by the mailing list yet. Hi All,
I am new at Qgis and I enjoyed and find it usefuşş for most parts. I
am currently using map info for some buffer analysis and had some
problems about trying to do same analysis in qgis.
I am trying to put a ring buffer for 100m. I converted 100m into
degrees since my default projection in qgis is wgs84 epsg:4326. I
putted a point got a ring in qgis.

If your projection is EPSG:4326, units are in degrees. So your buffer in
QGIS is not 100m, but 100°. You have to reproject your data to a CRS
that has metres as units, like UTM for your part of the world.
HTH,
André Joost
