Where to start on programming a map?

If I would like to take a small area on a map, and then use this small
area for a gps application, where would I start?

How are maps "programmed"? e.g. how is the gps device able to give the
user a route according to roads, rather than just linking the starting
point to the destination through bushes, parking lots, buildings etc?

I have been searching and reading a lot about the topic but I cannot
seem to find a starting point.

I would like to know where to start on this project, because this will
be the first step in a small gps application which will find routes
within this small map area.

Regards
