That is, only if his base map actually is in Mercator projection
(which I doubt).
Rich, first you have to find out the actual projection of your base map.
Only after that you can do the math.

If you are north american based you might get more info here: http://

Hehe
Google Mercator projection and start doing math . I started working
on maps
too and as I can see my employer uses Mercator projection algorithm to
calculate x,y. So my advice to you is to get started with that if
you don't
find service that will help you.
Greetings

Subject: [Flashcoders] custom map image geocoding service?
I'm building a flash app which requires some mapping
functionality. It's
relatively simple, so I'm not sure that it needs all the bells and
whistles
that come with using google's or yahoo's map services. Basically we
have a
static U.S./Canada map image (no pan or zoom) that has some
interactive
markers overlaid on it...pretty much a heatmap I guess. We're
already set
up with receiving the latitude and longitude coordinates, now i
just need to
translate that into x,y positions on the map. I know there are
services out
there that handle this, but I've been searching for a while and
most of the
results reference back to google or yahoo maps, so I'm thinking I'm
not
suing the right search terms. Does anyone know where I can get this
done...or any other tips/advice that might help?
Thanks,
Rich
