[Qgis-user] QGIS with digitizing board/tablet

[Thomas Colley]

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

 

Tom

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
