Getting Started
Website Sections
Data Frame: Window with the main map contents. It is controlled with tools in the Toolbar (B) or Control Panel (C). Toolbar: Initially open, this area has several tabs at the top with interactive tools for the site. Users can toggle the visibility with the button at the far bottom right end of the Toolbar. Control Panel: Initially open, this area has several tabs at the bottom of the section. These tabs will vary depending on the tools initiated. Users can toggle the visibility with the button at the far top right end of the panel. Overview Map: A small map window that shows a transparent blue area overlaid on a general map. It is helpful for occasions when the Data Frame (A) is zoomed into a small area. Users can toggle the visibility with the button at the bottom right end of the overview map.
Navigating in the Data Frame Map To start interacting with the map, use the Zoom Slider tool in the upper left-hand section of the Data Frame (A) or the tools on the Navigation Tab of the Toolbar (B) at the top of the webpage. To adjust the scale of the map, click on the Zoom In button or the Zoom Out button on the Zoom
Slider tool within the Data Frame. Alternatively, on the Navigation tab of the Toolbar, use the & tools to draw a square shape on the screen and it will zoom in or out of the area in the center of the square. To move the center of your view (Pan), left click and drag using the mouse in the Data Frame. On the
Navigation tab of the Toolbar, use the button then click and drag using the mouse in the Data Frame. To center on a FIAT Assessment Area, click on the button and choose the preset bookmark extent.
Home Panel The home screen is the initial tab shown on the Control Panel (C). It describes the website and gives hyperlinks to this document and other relevant websites.
Layers The Layers tab in the Control Panel (C) provides access to the list of layers the user can turn on & off to display data in the Data Frame (A). Users can click on the Panel Action Menu button at the top of the panel, to toggle between the legend and layer list.

Turn Map Layers On and Off
Visibility Confirm that the Layers tab is activated or click the Layers button on the bottom left area of the Control Panel. Now you can change which information is displayed on the map by checking the box [clicking within the box] next to the data layer you want to view. means that the data layer or grouping of layers is visible. means that the data layer or grouping of layers is not visible.
Data groupings A number of data layers together is a data grouping. Sometimes the group is not expanded so you can’t see all the individual data layers. If this happens, you can click on the plus sign to expand the group. To contract or fold up the data grouping, click on the minus sign next to the data grouping name.
Visibility of data in groupings To make the data layers within a data grouping (i.e. FIAT Analysis Products) visible you would need to check the boxes for both the grouping and each data layer you want visible.
Transparency Some layers or data groupings allow for adjusting their transparency (to see the layers drawn underneath them). Use the slider bar to the right of the layer or data grouping to control the transparency. If the bar is all the way to the right, there is no transparency. When it is all the way to the left, there is complete transparency.

I want to… The button on the upper left portion of the Data Frame is an alternative way of activating a select set of tools/buttons on the different Toolbar tabs.
Click on any one of the options and one of three things will happen: 1. An action will happen immediately. 2. Instructions may appear at the bottom of the screen 3. A new tab will appear in the Control Panel.
Calculate BLM Acres To initiate this functionality, there are two options. The menu includes a link to “Calculate BLM Acres”.
Alternatively, go to the Analysis tab on the Toolbar and click on the button. In either case, a new tab appears in the Control Panel. 1. Draw a polgyon in the Data Frame to delineate the area to be calculated. Click on one of the two shapes and bring the cursor back into the Data Frame. Draw the shape over the area of interest. Once you are done drawing, click on the Next button in the dialog box.
2. The Dialog box will change immediately. It will say “Processing…” at the top while the Viewer is busy calculating the acres of BLM surface land. This may take some time depending on the size of the area selected. Once it is finished a smaller dialog will come up in the middle of the screen with the acreage calculation.
3. Click the ‘OK’ button when you are done. A blue outline of the calculated area will appear in the viewer. 4. To delete the blue outline, right click on any place in the Data Frame and choose the “Clear Markups from Map” option.

Getting Details for Map Features There are two ways to display information about layers in the map through interaction in the Data Frame. Map Tips and the Identity Tool.
Map Tips A single, left click anywhere in the Data Frame results in an informational popup called a Map Tip. It briefly lists information about the layer(s) at that spot on the screen. The Base Map layers will not show in the popups.
OR
If more than one data layer is in the same spot, use the drop down arrow or directional arrows on the popup to change the information on the screen.
Click on View Additional Details within the popup to get a complete list of the feature’s information for the layer in the dropdown menu of the dialog box. The details will display in the Control Panel, the feature will highlight in the Data Frame, and the popup will disappear.
