What might be REALLY useful is a LEGAL clone of Google's "mld" image
server. I have produced polys directly with Google's "mld" image
server but I doubt it is legal. I will be happy to share what I have
learned about their encoding algorithm.
Yes, please post your code. I may not be able to use it but someone
else could. If enough auxilliary tools for static maps are developed,
Google may do something to trim the bloat from their dynamic maps.
Modularization is helpful but it does not significantly reduce the
infrastructure. A 200KB gorilla is not appropriate for every
application.
I updated "adjust.js" a few days ago. It now has inverse functions:
LLToXY
XYToLL
I agree with your desire to combine Google's map with your markers at
your server but it is unlikely to happen. It is much more efficient
to send one file than several over a potentially slow link. Combining
overlays in the browser impedes both panning & zooming.
