Tom -
A few pointer to a more productive environment:
* (As we already agreed upon) No paper maps and digitizers: Scan the
maps and use a mouse and monitor
* Get the largest monitor to the digitizing operation your budget will
allow (24 " or 27" is nice).
* Whatever you are using QGIS, MapInfo or ArcGis (or whatever): Make a
row or two with buttons, where the separate button activate some
kind of desired function when digitizing. The digitizing user should
not need to go looking for digitizing functionality in obscure
places in the user interface. Be aware, that the only way to survive
mind-numbing work as digitizing, is to "switch off" the brain. That
means you have to design the user interface accordingly.
* The work-flow should include that the digitizer user always make a
backup-copy of the original material before starting new digitizing.
* Save often/early.
It might sound like a lesson "101" (and it is) but a lot of people seem
to forget it.

I agree with you 100% on georeferencing scanned rasters being a much
better option! There wouldn't even be any cost to the scanning as we
have a large format scanner and many of the plans are electronic
anyway meaning they would have to be printed off to be put onto the
board and digitised!
I thought that maybe I was missing something as I'm not from a
hardcore drawing background as the users were maintaining that they
needed to use the boards even when I showed them the excellent
Georeferencer in QGIS. It sounds like this might just be an excuse for
them not wanting to move away from ArcGIS!
Thanks very much for your reply

To Thomas -
It would probably not be exceedingly difficult to create a plugin that
would let a digitizing board work with QGIS.
But just my 2 cents as an old digitizing monkey way back in history:
Productivity- and operation wise, it's a far better deal to scan your
maps - whatever size they have - at your local printing shop and then
georeference the rasterfile(s) once and for all. Trust me: It will
beat the digitizer setup almost all the time - even when you include
the cost of scanning the maps at a printing shop.

Hi Nathan
Thanks for replying. From what I can understand it's just a case
of georeferencing the drawing on the board in the same way as you
would a raster on the screen.
ArcMap takes a text file with at least 4 coordinate pairs from the
drawing on the board that it uses to tie the digitizing area into
the on screen CRS.
So I hope it might be relatively easy to implement a plugin that
can accept these coordinates then apply some sort of shift to any
input from the drawing board.
I'll try and get some more info on how it works in ArcMap.
Thanks again
Tom

Hey Thomas,
Wouldn't it just pick it up like a mouse? Qt does have support
for more pressure based devices but QGIS doesn't take advantage of
it. It will work fine if it acts like a mouse though.

Hi
Is it possible to use QGIS with a digitizing board/tablet?
I've had a search but can't find any information on this.
The board I am trying to use is a CalComp DrawingBoard III that
our users have been using with ArcMap.
If it's not currently possible in QGIS I will look at creating a
plugin for it.
Thanks
Tom
