Could anyone familiar with both digitizers and grass let us know what
options are available. Pricing and ease of use information (plus the
availability of a grass driver for the digitizer) are appreciated.. | thanks,

We use Altek for digitizing (sorry, can't seem to find the
model-number). Both the A0 and A2 tablets work fine with GRASS, although
I'm not very keen on using v.digit for this. A few months ago I got a
script from Malcolm that helps you install various digitizers without
having to mess with the dipswitches. The reason we bought the Alteks was
the price: in Holland they cost 60-70% of the price of a Calcomp.
While I'm here, I have a question about r.cost. Does anyone have any
experience with the program running for an infinite amount of time, while
the percent-count increases to far above 100%? If so, have you got any
idea what could be wrong? I ran r.cost -v on a region of 177 rows by 223
columns with a slope-map as input map and a map of 69 site locations as
output map, but it can't finish the job. It worked fine however on a
smaller region. Any suggestions appreciated!
