Generated from the 1 arc second data but printed at 200 micron layer thickness (not 100). It prints faster and it still looks great and I was able to print bigger (about 4 by 4.5 inches).
Love your work. Hint about printing these big flat prints in PLA or ABS - use helper disks at the corners and sides of the print and a little bit of aqua net hairspray. I'm printing very large scale terrains (newest is 3'x6' of Valles Marineris) on a 3DP Unlimited printer and that's the only way to keep things that big flat.
Thanks. But since the addition of a heated build plate with the new printer I can print any size. I still use a brim on large prints but no hair spray needed. I get nice big flat-bottom maps (that can be concatenated easily).
