Testing DQ checks: spatial - precision

[Mesibov]

Coordinate precision not valid ('Supplied precision of coordinates is not a valid value')
451867 false
5208 true

Precision / range mismatch ('The precision value should be between 0 and 1')
457061 false
14 true

I really don't see why 'coordinate precision' is any help to users, especially if uncertainty in metres is also recorded. ALA isn't testing it correctly, in any case, for example:

Failed the 'Coordinate precision not valid' test:
http://biocache.ala.org.au/occurrences/16712ec2-f510-4496-9a79-30028188e762
34° 45' 00" S, 146° 03' 44" E; -34.750 146.06222; precision 0.00001; uncertainty in metres 10

Passed the 'Coordinate precision not valid' test:
http://biocache.ala.org.au/occurrences/59623675-517b-4c7e-bb03-b122968dcabe
34° 42' 15" S, 146° 02' 52" E; -34.70416 146.04777; precision 0.00001; uncertainty in metres 10

I can only assume the first record failed the test because the decimal latitude wasn't recorded as -34.75000, which is a formatting issue, not a rounding one.

Then there are those 14- and 15-place DDs that ALA doesn't round off. Coordinate precision of 0.000000000000001? Really?

Note also that the uncertainty in metres is 10 in the 2 records above, which means the decimal lat/lons could be rounded to 4 decimal places with no significant loss of accuracy.
