Notes:
One of the most difficult issues associated with integrating multiple datasets from several states is creating a user interface that simplifies that list of available map layers. To overcome this problem we created a hybrid Table of Contents (TOC) and Legend using html and some simple JavaScript.
Table of Contents layers have been grouped into subject areas to help users find layers of interest. The subject titles at the top of the TOC have hotlinks to scroll to the respective part of the legend.

We also added additional functionality to the TOC by incorporating hotlinks to metadata files (where metadata is available) from the layer names.
Eventually, we will add hot links to metadata for all layers listed in the TOC.
