You might try using a UnionSet of 1080 Sets, each containing a
pair of lats and lons, for the domain Set of one FlaatField.
Each pair will be drawn as a line, but the lines in the union
won't be connected together. There will be 1080 * 2 range values
for this single FlatField.
Or you could try a FieldImpl with MathType:
(count -> (index -> (longitude -> latitude)))
where each range value is one of your 1080 FlatFields. Having
1080 DataReferences linked to a Display may be a bit slow.
Good luck, Bill
