I am new to GIS, know really nothing about coding or GIS. I am using QGIS 3.6.2, for which is it apparently hard to find up-to-date user guides.
I have made a map that includes road files and site locations. I added points along the road to be able to find the closest points on the road to the sites. I got an output that gives me the closest points and their distances, but cannot figure out how to get a line between these two sets of points. The ultimate goal is to be able to determine distances between sites using these roads.
