Some GPS-related Links (from Jim Wallis)...

Manufacturers...well, who is really in the handheld outdoor market, Garmin and Magellan are the main ones but Silva also have some.

Probably the best piece of shareware in the world, but only if you have a Mac! This up to date piece of software magic even works on my ancient powerbook 160 (System 7.5.5) with the addition of some extra libraries from apple. For PC users, their links page is really comprehensive too!

For Palm users try this out:
With the right leads and a mobile phone with a modem and infrared you can download maps as you travel, at any scale, and keep track of your position. I pre-downloaded some useful maps before we went to Washington and loaded in some co-ordinates of nice places to visit (like REI stores) - fantastic, on the first day I was able to give instructions like: "turn left at the fire engines and then take the 3rd left after that....".

I don't currently have any GPS software on my PC because compared to the above everything I tried sucked! There are however loads of utilities for transferring those all important tracks and waypoint files - many of which are listed on the GPSy website above.

For equipment these people are pretty cheap

...and for specialised leads if you can't make your own try these guys (actually in Japan I think).

GPS Maps

There are several sites where you can download maps including microsofts mappoint and our old friend streetmap

Unfortunately you'll have to do some calibrating yourself to make any use of them. The GPSpilot software actually gets into mappoint (actually vicinity which is now part of mappoint) and gets pre-calibrated maps that work straight away - I haven't worked out how to do this without GPSpilot though.

If you want to buy maps on CD try DeLorme who have a bias towards the US as do National Geographic

Garmin also have a range of map CDs covering the whole world, and also a range of charts

Many outdoor shops are stocking anquet's maps on CD but they seem hideously expensive compared to the American brands :-( Compare an entire state for $99 with the english lakes for around £100!
