[Geotools-devel] gpx module progress

[<bu...@me...>]

Hi,

I've comitted a new version of the gpx data store, that now uses 
Justin's xml parser (so xstream and xpp dependency dropped). It's still 
r/o, but write support is the next step.

I tried to add it to uDig, but failed to do so, so tested only with a 
simple test case (loading a file, and printing the loaded feature).

If you feel like testing, give it a try!

I also had a discussion with Jody on how to implement the temporal data. 
(in the gpx file every point of a track, so the nodes of a line segment, 
has lon, lat, elevation and time data). This could be used when 
visualizing the features. The easiest way might be to extend the JTS 
Coordinate class, to support a 4. dimension, which can be the Date, and 
create the geometries using these extended coordinates.

Has any of you worked with temporal data like this, or with any 4D data? 
Or just any idea on how this could be best implemented?

Best,
Peter
