Hi everyone,
I’m trying to use the qchainage plugin to create ½ mile markers along a vector
line that represents a trail. The line is a single feature with no multi-parts
or dangles. It is about 318 miles long so I would expect right around 636
points if there is one every half mile. My proje
Tim and list,

Depending on how the GPS data was collected for the trail, your line shape
may be longer than the actual trail. Each GPS point has some error and if
the points were collected at one per second, the additional length caused
by points being off the centerline, could be significant. GPS height i
Hi Stewart:
You could write a simple script using python or modeler to do what you

Much appreciated!
