I sent this to Adi instead of the mailing list. This could be of general
interest, so here we go again:

Adi,

What kind of maps do you use in Europe for GPS navigation on land?=20

If someone wants to use GPS in Sweden, you should use the red, blue or green
map:
The Red Map ("R=F6da kartan"): 1:250 000.
The Blue Map ("Bl=E5 kartan"): 1:100 000.
The Green Map ("Gr=F6na kartan"): 1:50 000.

I find the Blue Map a good compromise between detail and economy (buying
green maps to cover a large area is extremely expensive), but the red map is
also OK. It's much better than normal maps in the same scale.

These maps have a UTM grid, but the easiest grid to use on them is the
Swedish Grid. If your GPS handles the Swedish Grid and the RT90 map datum
(which Garmin and Magellan does), you will find these maps very convenient.

The maps are available in bigger book stores. They are published by The
National Surveying Institute ("Lantm=E4teriverket").

Keep sliding
