The contents of the catalogue have been tabulated and indexed in several ways, to facilitate locating specific surveys. The various tables and index maps are listed below:
The tables can be sorted on any column , in ascending or descending order, by clicking on the column title. Use your browser's Edit|Find menu option to search for specific text within the tables.
For the KML index maps, clicking on a star at the centre of each survey will pop up a balloon which displays the survey title along with a hyperlink to the survey metadata page.
