I've got an interesting project that I'm going to start working on next week, and I'm not quite sure how to tackle it.
I need to make a series of overview maps with an overlay of the map extents of my topographic map library. This in itself is easy enough to do. The catch is, I would like to label each extent / tile feature with a QR barcode, which will be available as as an image.
I know I can use pictures as label features - however there are several hundred map extent features and I don't want to label them all individually!
What are my options for using the QR codes as labels? The two options I can immediately think of (but are untested) is either to load the QR code into my map tile FC as a BLOB feature, or include a file path to the QR code.
Does anyone have any bright ideas? Thanks!
