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 project default is set to miles for
length measurements as is the qgis main preference. I set the unit measurement
to miles and input .5 as the interval. I continually get 771 points instead of
the expected 636. Also when I use the automatic labeling feature of the plugin
it appears to be in degrees not an aggregate mileage.
Several weeks ago a fellow had queried the list on the same subject. He
was working with the Appalachian Trail I believe and wanted to place points at
given distances. No one seemed to really understand so I’m hoping that if
anyone remembers the original poster, and has come up with any thoughts or
other ideas it would be much appreciated. This is something that can be done
for sure. All of the National Scenic Trail maps in this country are demarcated
with some form of mile or half mile makers which when labeled show the
accumulated distance.
Hoping for some traction on this. I’ve only just started learning python
so I wouldn’t describe myself as a programer and am looking for a relatively
simple solution.
With much gratitude,
Tim Fearn
