I want draw a corridor indicating a right-of-way around a road. The right-of-way is 300 ft. i.e. 150 on either side of the centerline of the road. Here I show just lines that I have hand drawn, very poorly. How can this best be done?
In Google Earth Pro? I'm not aware of any way to do this other than how you already started.
In QGIS, it would be trivial , using the buffer tool, as documented here.
