This question already has an answer here:
computer science student here, haven't done much in GIS, just trying to finish a project for a class.
What I have is a CSV of origin/destination points as co-ordinates (longitude and latitude)
what I want to do is to create a heatmap of the routes, similar to a traffic heatmap that you see on google maps.
ie. I want more frequented pieces of road to be red, and less frequented to be green. not just the more frequented origins/destinations, thats trivial.
what's the easiest way to do this? I have experience with python, java and matlab.
I was wondering if there is a free software that could do it straight from the CSV? or maybe a python module?
edit: since im using just a CSV of origin/destination points, I believe it is not a duplicate, since the referenced post used GPS tracks, which is quite different information.
