Warning: This is a seriously nerdy blog post. If you just want the B.C. FSA boundary files and not my long-winded explanation of how I made them, you can get the SHP file here and the KML here. But if you’re a mapping nerd and need help making complex boundary files simpler, read on.
On a semi-regular basis, I find myself creating maps based on postal code areas. Or, more technically, Forward Sortation Areas ...
