I noticed this news story today:
“Sheikh Hamad Bin Hamdan Al Nahyan wrote his name two miles across — with letters a kilometre high. It is so huge that the “H”, the first “A” and part of the “M” have been made into waterways. The mega-rich sheikh, 63 — a member of the ruling family of Abu Dhabi — in the oil-rich United Arab Emirates — boasts a £14billion fortune that is second only to the Saudi king’s.”
For fun I took a screenshot of the satellite view, cleaned it up a bit in Photoshop and ran the result through http://new.myfonts.com/:
I reckon Suredog (bold) is a good match… should you wish to write your name on your beach in 1 kilometer point size.
