==== Processing ====

Clicking on the ''Show Topo'' button will open a popup window. If multiple surveys have been selected, the top of the page will list the surveys. Selected surveys that do not have topo data recorded are indicated by an asterisk.  The first survey with topo data is selected for display by default.

On the topo chart the location of the clusters with matching elements appear in red and enclosed with "=" characters.  The functionality of the chart is similar to the '''Show Topo''' function.  All the cluster numbers are hyperlinks that open popup windows to display additional cluster information.
