I am new to qgis and I would like to create a buffer around point features.
My goal is to create a quarter mile buffer (402.336m) around each point feature, using Geoprocessing Tools -> Buffer(s), setting the buffer distance and exporting. The process creates what appears to be a massive polygon. However when I use '.05' as the distance buffers appear around each point.
I assumed this happened because the measurement units are not correct. I verified the project projection (NAD83 OH/South). Then I checked the Measure Tool via Options -> Map Tools. Te ellipsoid for distance calculations set at WGS 84 and the Preferred Measurement Units is set to 'meters'
I have set up 'on the fly' projections
How do I solve the mystery of this buffer problem?
Setup: qgis 1.7, Ubuntu 11.04
Answer
You have to reproject your point input data to NAD83. FTools doesn't care at all about the project settings. The buffer will be created in layer units.
