Hi, I have a road network that is surveyed for road distress. The network is a line vector layer. I also have a point layer representing the driven trajectories of the survey vehicle. I am looking for a method to update a field of the network layer when [some] points of the trajectory are "near

Hi, It’s not clear to me what you are looking for but it seems you have information from points that you would like to have updated based on the lines. This is impossible because they are not touching (a very hard thing to do btw). You could snap the points to the line. Look for “snap“ in Pr

CVS import of DMS coords is touchy in my experience. The degree symbol ° fails while º works.  Under Mac OS X 10.13 the first is Option-Shift-8, the second is Option-0 (opt-zero). Also, it seems to want ' for minutes and ' ' for seconds, i.e., a single ' and two separate '. It rejects a normal "
