@sybren I've done a few elevation and touchmaps for blind people and it's been hugely rewarding. One of the lovely remarks was he didn't believe that what he was touching were trees, because they were higher than the houses and he just never knew that was the case!

If anyone has photos they would like to share of the EMF camp map I made, please do! I'd love to see them. #EMFCamp #nullsector
