Complicated Conundrum #2 Mystery Cache

The second cache in a series of puzzles that I get around to making every now and then. Needless to say, the cache is not at the published coordinates, although it does take you to a very nice meadow. This cache can be attempted at any time of the year, and you're guaranteed to see arguably one of the best views across Canterbury on your way to the cache if approaching from Neal's Place Road. To obtain the actual coordinates you will need to solve the following puzzle:

N51 17. (Star - Crescent) (Triangle/Diamond) (Crescent - Donut)

E001 03. (Triangle - Star) (Star - Donut - Diamond) (Crescent - Diamond - Donut)

Once you do figure out what the shapes represent you will still need to convert them in some way to get the right values. :-)
