Mapping Records

The BSBI Distributional Database has many useful attributes.  For example:

Records in DDB May 2013

Records in DDB May 2013

Obviously this is a snapshot before Sunday when I sorted that vertical strip of three white tetrads in the middle of Skye. The database contains many, many duplicates and some records appear half a dozen times, so the actual numbers of records as shown are fairly meaningless, but the overall picture of tetrads with few or many records is useful.
