EPSG:3857 is in metres, are readily visible and as far as I can tell from measuring the buffers were correctly created in the correct size. In the buffer dialogue did you click on the button next to the distance / units pair and next to "field type >" select your field, which would deactivate the distance / units pair? Your mention of "lat and long" troubles me. EPSG:3857 is a projected coordinate system, not a lat/lon system. > > 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 > > On Wed, Dec 15, 2021 at 6:42 PM chris hermansen <[email protected]> > wrote: > >> Peter and list, >> >> On Wed, Dec 15, 2021 at 7:26 AM Peter Devanney <[email protected]> wrote: >> >>> Hi Folks >>> >>> Have a table full of points that I want to buffer by a variable >>> distance.
