Would you like to be able to print maps with the grid on it? Then people could discover a plus code for a place, or use the map to find their way to a plus code.
We think this would be cool, and was a reason for designing the codes the way we did - we didn't want to have something that only people with smartphones could use.
There's a website called
fieldpapers.org - they let you select an area and generate a PDF of pages with the map. We've contacted them and they're open to adding the plus code grid to their maps if people want to use it.
Unfortunately we don't have anyone to work on this so if you're interested, check out their github, and let me/us know, I might have a couple of pointers for you!
