The user instructions will cover an overview of how to interact with the viewer. There are 4 different menu sections of the viewer. Each menu can contain tools and widgets. Each widget contains a help panel specific to that widget. If you do not find the help you need below, please contact us at helpdesk@landfire.gov. 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. Each widget will have it's own help panel describing usage of that widget. 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. Full Extent - The Full Extent tool allows you to zoom out to the full extent of the viewer. Move Map - The Move Map tool is used to drag the map in any direction and recenter the view. Simply click on the Move Map Tool, then drag the map to a new location. Overview - The Overview widget displays a small map. The red box respresents the area on the main map that is currently visible. Clicking on the red box and dragging it, will move the viewable area of the main map. Bookmarks - The Bookmarks widget stores predefined locations that can be selected to quickly view a particular area or region in the map. There are 5 different panels within this widget.
	This is the map data sources portion of the menu. Tools and widgets in this menu allow the user to change or modify the data source or layers in the map view. Each widget will have it's own help panel describing usage of that widget. View Data - The View Data widget allows the user to turn available layers on and off. The transparency of the layer can be adjusted as well. View Legends - The View Legends widget allows a user to view the legends for the current visible layers selected in the View Data widget. Download Attribute Tables - The Download Attribute Tables widget allows the user to download pre-defined zipped files to be used for analysis. Download Data - The Download Data provides the ability to select data for download.
	This is the interactive widgets portion of the menu. Widgets in this menu interact with the map and the user to provide advanced functionality. Each widget will have it's own help panel describing usage of that widget. Annotate/Measure - The Annotate/Measure widget has several different drawing and measuring aspects within this widget. They are activated by clicking on the graphic within the first panel of the widget. They are explained in more detail within the Help panel of the widget itself. Elevation - The Elevation widget provides an interface to the USGS Elevation Query web service and allows for elevation queries to be performed. Gazetteer - The Gazetteer widget allows the user to zoom to a specific location using a Geographic Names Information System (GNIS) text search. Use various combinations of city names, county names and/or state names. Identify - The Identify widget allows the user to click anywhere on the map and will display the imagery source information. Legend Query - The Legend Query widget allows the user to view the legend color and description for a specific point based on the layers that are currently being displayed. PDF Print - The PDF Print Widget provides the ability to a create a PDF image of the toolkit as it is displayed on screen. Scale - The Scale widget 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. It then uses a geometry service to reproject that line to a coordinate system that uses meters and somewhat minimizes the distortion (UTM or Polar Stereographic depending upon latitude). Once that is done it uses the geometry service again to get the length of the result feature. 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 - The XY/USNG widget allows the user to query the map for coordinate information including U. S. National Grid coordinates.
