I have a set of points in a shapefile with a real number attribute 'r' containing a radius (cp. screenshot below) and I would like to buffer these with amount of 'r'. As the result I expect a polygon shapefile with approximated circles of various radius, but the resulting shapefile is empty.
What am I missing?
(I must miss something, because it seems impossible to me that such a basic operation does not work in such a great software, and furthermore this feature has already been mentioned in the 1.8. doku: "Variations in buffering: buffer distance or buffer size can vary according to numerical values provided in the vector layer attribute table for each feature." http://docs.qgis.org/1.8/de/docs/gentle_gis_introduction/09_vector_spatial_analysis_buffers.html)
My project CRS is EPSG:25832, point shapefile the same. QGIS version is 2.8.7LTR (but same symptom in 2.14.3.)
This is what my points look like:
This is how I configure the buffer tool (German GUI):
And this is the result (None):
