The user instructions will cover an overview of how to interact with the viewer. There are 3 different menu sections of the viewer. Each menu can contain tools and widgets. Each widget will contain a help section specific to it's own functionality. The main menus and tools are:

This is the map controls portion of the menu. Tools and widgets in this menu allow the user to interact with the map view and manipulate the location and scale.

	Zoom In - The Zoom In tool is used to enlarge a portion of the map. Select this tool, then click and draw a box on the map around the area what you wish to see in more detail. Clicking without drawing a box, will zoom in with the center point where you clicked by a factor of 2.
	Zoom Out - The Zoom Out tool is used to zoom out of a more detailed view of the map. The box drawn with this tool is used to calculate a zoom out factor. A smaller box will zoom out more than a large box. Clicking without drawing a box, will zoom out with the center point where you clicked by a factor of 2.

Scale - This tool works by determining the current map units per pixel, and then creating a line that is 96 pixels long (~1 inch on most monitors) at the center of the map. The scale is expressed in 1 inch = x inches by default, but that can be changed by selecting a different unit of measurement from the drop down list. The feature created to measure the scale is a horizontal line.

XY/USNG - This tool allows the user to query the map for coordinate information including U. S. National Grid coordinates.
