[Qgis-user] QGIS with digitizing board/tablet

[Thomas Colley]

Thanks for that Benoit! I’m worried that something as new and radical as FORTRAN IV code from 1986 might be too much of a leap forward for these users. Judging by the shade of yellow on the drawing board it’s of around the same vintage!

 

Thanks again


Tom

Hi Tom,

Perhaps the following reference could be of help to you when you start writing the plugin:
Computers&Geosciences: 1986, V12, pp175-197 - DIGMAP: a computer program for accurate acquisition by digitizer of geographical coordinates from conformal projections. (FORTRAN IV code on a Z-80!!!)

Regards,
Benoit

	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
