I have two datasets of different points in the same coordinate system, which describe the same line (road), so I want to see the difference in elevation between them.
I've been told that I should transform them to lines and then find the intersection points and calculate the difference in elevation there. But how can I do it in QGIS? Is there any plugins that I can use to somehow present the points as a route and then compare the two routes?
The first dataset derived from NRTK (vrs) measurements during a kinematic positioning on a road (1518 points). The second dataset derived from measurements by total station 30 years ago (100 points) so there is no common point between the datasets. I need to describe the elevation difference of the road, so I have to find a way to compare the datasets. Both datasets represented as E,N (projected), H (orthometric).
