coordinates conversion

[Massimo Vincini]

Marco posted:

I have to import a tiff map in to a raster map with latitude/longitude
projection (with use of r.in.tiff && r.rectify).

For this tiff map i have the coordinate of the upper left vertex
in the `GAUSS BOAGA timezone 1 system' and i need to convert these in
latitude/longitude.
The questions are:
		 - What does `GAUSS BOAGA timezone 1 system' mean ?

It' s an old Italian modified UTM projection which uses it's own 
coordinate system and Rome 1950 Datum.

		 - How can i convert these in latitude/longitude ?

I suppose that the easiest way is to get a map of the zone with both 
Gauss-Boaga and geographic coordinates (there are several).
 
		 - Where can i get some docs about this ?

Any Italian cartography text should be usefoul.

Hope this helps.
Ciao.
