For each HEC-RTS module, there is an associated map window, and for each map window, the layers available are different. When you click on a module tab, in the HEC-RTS main window, a Map Window will display. From the Map Layers dialog, from the Currently Opened Maps box, the currently opened module map windows are listed. Selecting a module, will display the associated layers with that module in the Layer Tree.
