digitizing w. GRASS

[Max Grad]

Hi there ,

I am considering GRASS for data acquisition with an ALTEC 
Datatab 2 digitizer. Can someone help me with the following 
questions:

1.) Are there any problems connecting this type of digitizer to 
Grass ?


2.) What is the (numerical) accuracy of digitized data in Grass 
? Here in Germany, we use the GAUSS-KRUEGER coordinate system, 
which gives values like 4324123.45 meters (Long.) and 
5345672.78 meters (Lat.). In other lowcost (or shareware) GIS, 
a round-off takes place after the decimal point. eg. TOSCA 
(from Idrisi) would store the above values as 4324123.5 and 
5345672.
What does happen in GRASS ? (this is the single 
precision/double precision story in ARC/INFO)

Can someone help me ?

Regards
