Period period Mystery Cache

There used to be something at the given coordinates that may have assisted in solving this puzzle (a restaurant called 'The Fig Tree').

This was part of what I studied at university though have found no practical use for it since then. Until now!

Then the cache is located at:

N A ° B.C-D
E W ° X.Y*Z

Where

A →60
B →28
C →101
D →93
W →7
X →66
Y →13
Z →34

The final cache is within 1Km of the given co-ordinates, which should put limits on the admissible values of A-Z, C and D have the appropriate number of digits
