Great explanation and thank you very much. I have just recently become
familiar with GPS in a small way while attempting to track a friend across a
distant area. I have been tracking with the Nextel Mobile Locator which
works just ok. I just purchased MS S&T 2005 but only see the US for the most
part. I was wondering if there were any versions of this type of mapping SW
that covered Jamaica. I am sure that when I finally buy the hardware I will
be familiar with much of what is available. I also ordered Delorme Street
Atlas USA 2005 which I am pretty sure will not be any better than S&T.
Thanks

You can also convert any GPS-reported coordinates to normal lat+long,
so that any bog-standard atlas or map can be used. For Montserrat,
for example, there is a detailed local map which has some lat/long
points overlaid, so you can derive locations manually from that.

Great. I am just getting familiar with GPS and can see there is a bit of a
learning circle involved.

My guess is that the market is considered to be too small for a
commercial product.
My suggestion would be to buy paper maps and scan them. Then use
Fugawi or something similar if you want them to be coupled to a GPS.
There are a number of map store which stock foreign maps. There are
excellent IGN maps of the French islands - Martinique, Guadeloupe, and
all of St Martin/Maarten. These are available in 100,000:1 and
25,000:1 scales. The British have produced good maps for some of the
(ex-) British islands, but they may be hard to find off-island.
Do a Google search for maps or map stores. I turned up the Jamaica
National Land Agency this way.
AS a hint, I'd try for stores in the UK for maps of the Caribbean
Commonwealth countries. It's pretty easy to order from the UK with a
credit card. I've bought a computer street map of Europe that way.
I'm trying to remember the outfit I did business with. | |

| | Guest | GPS for the caribbean Jimmy, the Delorme SA 2005 is a pretty good program. I use it all the time
when traveling in the 50 United States. The GPS receiver works well when
placed on the dashboard and plugged into my laptop. There are a few roads
that haven't been updated for a couple of years that I frequent but their
route planning software will still get you there. While the GPS unit will,
the mapping program won't work outside the US at this time.
They also have a program called XMaps but I don't know how well their GPS
unit interfaces with the XMaps program.
