[Qgis-user] Buffer by Attribute Issue

[Peter Devanney]

Chris

The buffer input is a point the lat and long are Doubles. The buffer
distance variable is a Double. Using EPSG 3857 for all.

Not sure what the protocol on the list is or if it will accept a small 2 MB
.mp4 but I can show what I am doing for workflow if that might help?

thanks Chris

Peter
