I'm an amateur GIS enthusiast who maps my runs, hikes and urban explorations all over the place. I have accumulated hundreds of GPX files which I enjoy visualizing in different programs - but all of them fall short for one reason or another.
Googling just brings me to a lot of nonsense about interoperability between different run tracking programs and google maps.
Do any of you experts have a suggestion for a tool that will let me visualize all my GPX tracks in one world map? The closest thing I came across was umap but it had some annoying artifacts with certain files.
