It's all greeking to me. :P


Even on the pdf at 100%, but it may be my old eyes, too. :/


As long as it works for you it's all good. :)


I think the distance labels on the small globe, bottom left, are a bit small at 100%. I'll enlarge them. But on the PDF if you zoom in they will render completely clear

David this is brilliant.


There is always the pressure to measure to that extra decimal point because it looks good and scientific irrespective of whether the precise location is visible on a map.

It's a good illustration for knowing the concept of distance in degree. Sometime I also have no idea how precious I need for coordinate conversion between decimal

degree and projected coordinate. Obviously it would be enough to process the decimal degree data up to six digits.

Great. I like the cheat sheet and the link to the Practical Cartographer's Guide. Learn something useful every day. Thanks.
