Firstly, thank you for your timely assistance in this matter. This is the beginning of a journey for me to parse a lot of data through Maple ready for analysis.
Clearly I am waaaay behind in my knowledge of how Maple plotting and mapping works, and I'm going to spend some time working out what commands like
[1, 2] = COLOR(HUE, ListTools:-Flatten(convert(G, listlist)))
The data comes from satellite measurements and so there are gaps in the coverage near the equator, hence the streaks. The break in the meridian is a feature of the data that I need to get back to the curators on.
Can I ask you where and how you learned so much information on Maple and plotting? It seems that the help files are difficult to parse and have poor examples. There must be a much better source of information in a book or other resource somewhere?
