I am playing around with gps data from a tracking company and need
something that can easily visualize gps tracks.
Have you looked at OpenLayers, which is Javascript for the web browser?
It lets you display GPX files on top of map tiles (such as Mapnik tiles
or even some aerial imagery sources).
I did this some time ago for visualizing a route that I drew in JOSM. I
highlighted some ways in JOSM and exported them as GPX. But, it sounds
like you could skip the JOSM step altogether.
Another option is to somehow render the data to map tiles and display
those as a transparent layer on top of the base map layer. There are
several web pages like this, highlighting public transit routes, skiing
routes, you name it.
On the server side it is very easy, you are just serving static files.
Even the background map tiles would not have to be stored on your web
server.
If you are looking for a non-networked solution, you could check
MyTourbook, which is an open source Java application. It will display
training data from bicycle computers on top of a map. The colour of the
trace can visualize different things, such as the speed or the heart
rate.
Best regards,
Marko
