Full dataset to Chart Datum including the relationship between IGLD85 and Chart Datum. were supplied but to 2 decimal places only.

This year, rather than just sending the latest year of data, the complete dataset has been supplied. This has highlighted some differences in the data. From communications in the correspondence file for 2002 it appears that the Oceans and Fisheries meant to supply revised data for the stations supplied. This did not happen. The complete dataset includes these data revisions. Therefore, the whole dataset has now been re-entered.

It has now been confirmed from the Canadian Authority that the historic data for 1900-1903 should be ignored as there is no supporting metadata for these data.
