I am trying to buffer around a polygon with the buffer measuring 1km from the edge of the polygon rather from the centre? How best can I achieve this please?
Thank you!
Hi Hannah,
I believe the Bufferer transformer in FME uses the boundary (and not the center) of the input geometry to expand or shrink the geometry by the amount you specify. So I think that transformer is already suited for your task!

Hi,
the Bufferer automatically extends from the edge, not from the centre. Example:
The inner polygon has been buffered 1000m.
Be aware that the buffer amount is specified in ground coordinate units.

Thanks! All sorted now :-)
