Of course you *can*.  The question is whether you need to, and whether
there is a benefit to use either a text, binary, or other storage
format.

First thought: I'd suggest dynamically generating .GIF's of the map
(perhaps even a single large .GIF covering the entire world), and then
exporting from that a sub-.GIF to the client for the segment he's
interested in.  The .GIF format is widely documetned, quite simple,
and has extensive libraries available for its manipulation.  PNG is
another (quite likely better) format.  JPEG would seem problemic.
