MATLAB mapping toolbox?

JesseC

I have a GPS track I'd like to plop on top of a map. The region of the track is very small, no bigger than the area of a city. I also have a bunch of shape files to build up a map of the city with all the buildings, roads, etc. in separate shp files. Although the shape files actually contain data for an entire region, I'm only interested in the a small portion of city.

Does anyone know how I would go about doing this? Or could they nudge me in the right general direction?

(I'm pretty proficient with most MATLAB things but mapping is new to me)
