comment Classification of GPS trajectory
I already know these papers. Usefull but they are focus on how to do inference on trajectories and understand the type. It seems quite poor about description, and I need a description about it.

comment Classification of GPS trajectory
No, I just need to know the features that characterize different types of trajectories. e.g.: Pedestrian path are different from vehicle path because the first show low velocity and frequent change in heading. Marine traffic have no altitude feature. And so on...

comment Repository for GPS tracklog (better gpx format)
marinetraffic.com is a similar service.

Yes, but I haven't found no marine/air trajectories.

comment Attributes that characterize a geodetic track
I think to work in this way, gave me your opinion: INDEXING: Having a lot of gps trace, I can compute a single trace (i.e. a map). After this, I'll analyze gps traces searching for interesting pattern (e.g. meet to discover parking, congestion to discover trafficated road), once finded, I can enrich the map adding this info. RETRIEVAL: Then, if I need to search for a trace that have covered a congestionable road, it will be finded quickly through map info, than I just to retrieve the trace that covered that road. What do u think about? It's a bad idea for IR aspect?

I'm developing in matlab, this is a research work for my academic degree, the title is: "index and retrieval of geodetic tracks".
