GPS Datum for Walking in Italy?
Q. What is the GPS Datum in Italy
Stuart Dryburgh, Lenzie
A. The german company 'Kompass' produce 1:50 000 and 1:25 000 maps covering parts of Italy and are similar to the Ordnance Survey Explorer Series (Orange Covers).
Each map is over-printed with a blue 1km square grid. This grid refers to GPS co-ordinates using Position Format: UTM and Map Datum: European 1950 - as indicated in blue type in the map key.
So for walking in Italy, in order for your GPS Device to match the blue 1km grid squares on your Kompass map you should set your GPS Device to:
Position Format: UTM/UPS
Map Datum: European 1950
To give you an idea of what this looks like - the GPS co-ordinates for the Monte Baldo Top Cable Car Station are:

A. On my Etrex vista I set the grid to MGRS (WGS84). That will line up the Italian Tabacco 1/25k and the Compass 1/25k maps to the same grid ref as shown on the etrex's satellite page.
