The attached jpg shows a chart of international weather symbols shown in a reference appendix and on a map in the reference appendix. How should this be transcribed: brailled, done as a tactile, or omitted?
I don't think that you should try to replicate the weather symbols as they appear in print. Are these symbols placed on the map according to weather patterns? If they seem to be necessary for the understanding of the reader, I would use a 2-cell alphabetic key to represent the symbol descriptions, and place the keyed label on the map.
