II.       Menu Control

The menu is used for navigation, option toggles, and to access functions with their own screens. The menu options vary depending on what functionality is in the current map configuration. The following options exist:

Map Overlay / Where Am I - The Map Overlay menu allows you to access the "Where Am I" feature.  Where Am I uses your device's GPS to track your current position on the map.  As you move around, the map indicator will automatically update to show your current location. To enable Where Am I, open the menu and select “Map Overlays”. This will bring up a screen that will allow you to turn Where Am I on. Click the Show button to enable Where Am I and to return back to the map. Once Where Am I has been enabled, the GPS device will start searching for satellites. The status of this including the number of satellites and accuracy will be displayed in a bar on the top of the screen. Once the GPS device has a location fix, the Map Viewer will center on the location. If Follow Me has been enabled, then the Map Viewer will re-center on the GPS location when it goes off screen.

III.    Using the Pointer 

Panning and Zooming functions from the keyboard use the center of the map as their basis (i.e. if the "5" key is pressed, the map will zoom in on the center of the map). If more precise control is required, the pointer arrow may used by selecting the appropriate Pointer Action from the menu.   

BlackBerry smartphones with a trackball use the ball for pointer movement. BlackBerry smartphones with a trackwheel will move the pointer up and down with the wheel alone; left and right if the ALT key is pressed. BlackBerry smartphones with a touch screen move the pointer around by touching the screen. A Pointer Action is performed by clicking on the screen.   

IV.      Changing the Map View 

To use map schemes in the Mobile Outage Tracker Device Application, select "Pick Map View" from the menu or press the "A" key while viewing a map. A list of all map schemes in the map configuration will be displayed. Choose a view from the list and click on it to activate the map scheme. The map will redraw using the new scheme.   

V.         Identifying Features 

After loading a map configuration with Layer Selections enabled, set the Pointer Action to Identify. If the configuration is set to be able to identify more than one layer, be sure to set the desired layer by selecting Pick Identify Layer from the menu. Move the pointer over the feature (e.g. Power Outage Triangles) to Identify, and then click on the feature.     

To return to the map display, choose "Close" from the menu. While the feature is still selected, selection options will be included in the menu. The "See Identify Results" option will display the selection attributes. The "Clear Identify Results" will remove the feature highlight from the map and clear the selection attributes.   

VI.      Using Searches 

After loading a map configuration with searches enabled, choose the "Search" option from the menu or press the "Q" key to display the "Pick a Search" screen. A list of searches defined in the active map configuration will be displayed. If there is only one search present in the Map Viewer configuration, the search list will automatically jump to that search.   

Highlight the appropriate search and click on it to display the search form. Fill out the form and click on the "Search" button to perform the search. A list of records matching the search criteria will be displayed. Highlight a search result and choose click on it to display a detailed record view of the result or click on “Show Results on Map” to display all the search results on the map.
