In this task, you will create a new HEC-MetVue Session for the Bald Eagle watershed. Sessions provide a work area for organizing your sub-work units (Map Windows). While there is no right or wrong way to organize Sessions, one approach is to create a separate Session for each watershed within the HEC-MetVue project. 

Create a New Session.

Right‐Click on the Project File node in the Explorer Window.

Select "New Session" and name the Session after the watershed, "Bald Eagle."

Press OK to create the Session. 

Notice that the maps you added in the Project Defaults (Task 3) have been inherited by this new Session and that a new, blank Session tab has been added to the right of the explorer window.

Create a New Map Window.

Map Windows belong to a Session and are the windows in which all maps are drawn and data is displayed.

To create a new Map Window, right‐click on the "Bald Eagle" Session.

From the "Sessions and Maps" option, select Add Map Window.

We will be adding Radar data to the Map Window first, so let's name the new Map Window "Radar" in the dialog that pops up and press OK.

Notice that the "Radar" listing has now appeared within the Explorer Window and the "Bald Eagle-Radar" Map Window is now visible within the "Bald Eagle" Session. The Map Window displays the shapefile maps of the US and Bald Eagle watershed delineation in the middle of Pennsylvania.

Now that you have created a new "Radar" Map Window, it is time to add in the gridded data.
