I need a DRG (topographic map) viewer that can accept
positioning scripts, as opposed to mouse click positioning.
What I mean is, I want to be able to open a DRG and zoom
in to a given spot by passing the lat/long coordinates and a
zoom level, all by keyboard commands - no mouse
movement or clicking needed.
The following free program can do all this with mouse clicks,
but apparently not by keyboard commands:

Here is the same thing in Unix:

I'm on Windows right now, but plan to migrate to
Linux in the near future. If I purchase a solution, I want
to pay less than $100.
I'm thinking about writing my own viewer. I'm pretty
proficient at Perl, and might do some research and write
my own program. If anybody has any suggestions along
these lines, I'd like to hear about it.
To give you an idea of how little I know about this, I
understand DRG's are tiff files with some underlying,
embedded spatial data that allows viewer programs like
these to show the lat/long and UTM position data for the
mouse pointer position. I thought I had a file describing
this, but I can't locate it now. So I'm heading to the web
for research.
