I realised that I left a step out of my procedure for developing and measuring planet maps. For those who do not want to go back to find the change, I reproduce it here.
After the part about selecting a map from the slush:
[EDIT="I skipped a step"]
III-B: Surface areas
First determine the surface area of your planet(4*pi*radius^2).
For this planet, with a radius of 3,400 miles, we come up with an area of ~145,267,244 square miles.
To determine the area represented by each pixel, we divide the area into the number of pixels as determined by the mollweide field histogram: in this case, 641,661. So we get that each pixel represents ~226 square miles. Planets are big.
The pixels are small enough that I can assume they are on a flat surface with only a small loss of accuracy. So lets take the square root of the pixel are to get the approximate size of each pixel. That gives us squares about 15 miles on a side. This is adequate for short trips, but you can expect distances to be fabulously inaccurate over long trips.

Also, I'm going to attempt to reproduce Hyphen's Tavonni map using Bryce. I foresee headaches.
