I'm using QGis and would like to convert the progressive mileage of a highway into latitude/longitude coordinates, but I have no idea how to do it.
I have a Csv dataset where there are several "geo-referenced" information with the progressive mileage of the highway. The Dataset takes this aspect:
+--------------+---------------------+----------+
| Highway name | Progressive mileage | FeatureS |
+--------------+---------------------+----------+
| A | 400.1 | ... |
| A | 430.2 | ... |
| A | 520.5 | ... |
| B | 22.8 | ... |
| B | 50.3 | ... |
+--------------+---------------------+----------+
What I am trying to do with QGis (or welcome if there is an easier way) is to translate the progressive kilometers of the highway into latitude and longitude coordinates. This in order to subsequently represent each feature of the dataset on the map. About the progressive kilometers of the highway, I know that is known the latitude and longitude of the initial mileage (km 400).
My goal is to have the possibility to make geographical queries in which reporting the name of the highway and the progressive mileage, I get the latitude and longitude of the point
How could I fix this?
