Re: [Qgis-user] Idea: Crowd-sourcing a batch-georeferencer plugin withQR code ?
Thanx guys for the hint, but this is a "serious" project ;) My detail maps I have to produce are scattered around an area of ca. 200 sqkm, I want to have the freedom to design everything I want to with overview maps for finding the spot, inserting already existing data etc. So fieldpapers.org is nice, but doesn't bring me any convenience in my QGIS-workflows.

Hi folks, I am facing a project, where I will produce hundreds of field maps with atlas from lots of small locations, which get printed for surveyors to fill in observations in the field. Getting them returned, I need to scan them, georeference them and finally digitize the features found. Alone thinking of the process of georeferencing all those scans (which might only have tiny offsets and shifts because of lousy scanners) make me wish to have chosen another profession ... So here is the idea: An atlas plugin, that will automatically distribute minimum 6 cross-hairs (or other automatically identifiable features) around your atlas canvas. A QR-Code is generated, which holds the coordinates, EPSG and name of the atlasfeature, and which is put in some restricted area of the composer map. Maps are printed, processed and scanned afterwards. Batch-import all scans. Another function reads the QR-Code of the scan, identifies to locator features, gives them the proper coordinates and automatically creates georeferenced tiff/png/jpg with the name of the atlas feature. Sounds like a dream, but I think there should be enough dreamers around to make this one true. Any ideas if this will work, and how to start this endeavour?

Re: [Qgis-user] Idea: Crowd-sourcing a batch-georeferencer plugin withQR code ?
Let me echo Brent Fraser suggestion to look at Field Papers, fieldpaper.org. They accomplish what you are looking for. Each page of the field paper has a QR code for georeferencing. Not only that they can be loaded in as a baselayer in OSM editors. The site fieldpapers.org has a simple walk through on how to go from nothing to pages loaded in for digitizing. If you are going to use Field Papers with different surveyors from those who digitize the results, make sure you have a common understanding of symbols and notation the surveyors use. Otherwise digitizing may be limited. Hope this helps.
