This is already a reality.  One such system is the software FishMap which
I developed to produce publication-quality maps.  It has two versions: a
stand-alone version, and a version that works with MUSE.  The MUSE
version, in addition to being able to create coordinates from
on-screen maps also performs gazeteer searches of the kind described by Julian

To see published maps produced by FishMap using exactly the kind of technique
described by Doug, see Icthyological Exploration of Freshwaters, 4(2):97-154.

Please note: anybody on Taxacom replying to this trend shuld also email me
directly, because I just set Taxacom to NOMAIL for a couple of weeks (I'm
about to leave to visit museums in Europe).
