3D Relief Map - Gros Morne National Park Canada

A passion project I've been wanting to do for so long! This was a Christmas gift to my Grandfather who is obsessed with maps Gros Morne National Park in Canada. He passed that passion for maps onto me and I've always wanted to try my hand at some of the 3D style maps I've seen others create.
After trying many different ways to get the look right, I ended up creating this using a terrain height map and lots of painstaking shading in Photoshop.
