I am trying to provide a data layer in QGIS 3.24 to show areas where further survey is required along an existing line. I have data with a start and end point in a .csv as below.
I want to use this data to select these 2 points on this predefined line and highlight the line in between the 2 points and not all the other lines either side. I don’t won’t a straight line between the 2 points but to follow the existing geometry. Each length between3.24 the start and end point will be a different distance.
Any ideas on the best way to do this when you have a large amount of data?
