I need to create a google maps web application, where I can import a GPX file to show the route visually as an overlay on the map. After the import I want the result to look like this!
How do I do this. I'am using python django
Hope someone can help
I can't help with the GPX/python/django side of things. However if you can presumably get a set of data with latitude and longitudes for all the points along your route, this code will create the route for you.
