Hey Jason, Imports are quite the pain to try and do - there's a whole process in place now to do them. It stems from the experience in the States of an import more than a decade ago of the TIGER data (from the Census Bureau) that is still being fixed after pretty large amounts of time working through it.
There could be multiple reasons for all of the road splits you're seeing- one is that in most import data sources roads are split at traversable intersections (as you would find in most GIS datasets), another reason is that in OSM streets are split wherever there is a change in attributes, for example where speed limits change, turn lanes appear/disappear, surface types changes, or there's a bridge. It might be worth trying Esri imagery. I've noticed in the municipality I work for, as well as others in the Toronto area, that they buy the aerial imagery that we commission them to fly every spring. It might not be the freshest available, but I've found the accuracy to be more accurate than other commercial imagery available. ------- Kevin F On Tue., Jul. 7, 2020, 1:02 p.m. Jason Carlson, <ja...@starlandcounty.com> wrote: > While waiting for a response I think if I import roads that already exist > (albeit incorrectly) it will possibly be just as much work to fix.
