Viewing Data Using Tracking Viewer

Prerequisite:

Tracking Viewer requires that a supported version of the Adobe Flash Player be installed on the web browser that it is run in. The machine where Tracking Server is running must also have the Flex Policy Server running, so that Tracking Viewer has permission to access it. The Tracking Server Controller can be used to start the Flex Policy Server.

Tracking Viewer can be run either remotely (on a different machine than the Tracking Server it connects to) or locally (on the same machine as the Tracking Server it connects to). Also, Tracking Viewer may or may not be deployed to a Web server.

To use Tracking Viewer remotely, it is best that it be deployed on a Web server such as Apache or Internet Information Server. The Tracking Server Post Install application can be used to accomplish this. For more information, refer to the Tracking Server Install Notes document that was provided with your software.

To view real-time tracking services using Tracking Viewer, follow these steps:

Steps:

1. If you are using Tracking Viewer and it is deployed on a Web server, open a web browser and enter the following URL: http://<host_name>/TrackingServer/Viewer/index.html. For example, if you are connecting to Tracking Viewer and it is deployed locally, you would use: http://localhost/TrackingServer/Viewer/index.html. If you are connecting to Tracking Viewer and it is deployed on a machine named xyz, you would use: http://xyz/TrackingServer/Viewer/index.html

   To run Tracking Viewer if it is not deployed to a Web server, you must enter the full path to the Viewer/index.html file in a web browser, or simply open the file. A typical installation location for the “Viewer” folder is C:\Program Files\ArcGIS\TrackingServer

If your web browser has a supported version of the Flash Player installed, you will see Tracking Viewer in your browser. If not, you will be prompted to install a supported version of the Flash Player.

By default, Tracking Viewer is initialized to show a complete world map. If your Tracking Viewer has been configured, it is possible that your initial map extent will be customized.

2. In the Server field enter either localhost (to connect to a local Tracking Server) or the name of the machine where Tracking Server is installed.

   The default value in the Server text box is localhost. If your Tracking Viewer has been configured, a different default name may appear in the Server text box.

3. In the Port field enter the client connection port of your Tracking Gateway.

   The port used is typically 5506. If your Tracking Viewer has been configured, a default value may appear in the Port text box.

4. Click the Connect button. The connection status should change to green and say “Connected”.

   If your Tracking Server has been configured to use authentication, you will also need to enter a valid username and password before you click Connect.

5. A list of available services from the connected Tracking Server appears in the Services drop-down list. Select a service you wish to subscribe to and click Subscribe.

   If your Tracking Viewer has been configured, it is possible that you will automatically be subscribed to one or more services upon logging in. In this case, you will see the subscribed services listed and features from the services should begin to appear on the map.
6. Features from the subscribed service should begin to appear on the map, and the tracking service should appear listed on the right side of the viewer.

   You can click on a service in the list to zoom to the spatial extent of the features in that service.

7. Click Symbology in the upper right corner of Tracking Viewer to configure the symbology of tracking layers you are subscribed to.
   1. Select the layer you wish to modify from the Layers drop-down list.
   2. In the Latest Observations section, you can change the color, size and shape of the symbols used to represent the latest observation for each tracked entity.
      Note:

      In order to use MOLE symbology, you must have MOLE installed and your tracking layer must support MOLE symbology.

   3. In the All Observations section, you can change the color, size and shape of the symbols used to represent all observations (other than the most recent observation for each tracked entity).

      You can also change the value in the Observations Per Track text box to change the number of observations that will be displayed for each tracked entity in the tracking layer.

   4. In the Tracks section, you can turn on track lines for your tracking layer by selecting a line style other than none from the drop-down list. You can also change the color and thickness of the line symbol used to draw track lines.

      Track lines are lines that connect all the observations belonging to each tracked entity. Track lines show the approximate path that an entity has followed.

8. Click Monitoring in the upper right corner of Tracking Viewer to enable monitoring of a single tracked object in a tracking service.
   1. Click on the latest observation for a tracked entity on the map in order to monitor that tracked entity. The latest observation for the tracked entity will begin blinking and you will see the attributes for the tracked entity listed on the right side of Tracking Viewer.

      You can only monitor the most current observation for a given entity. If you have chosen an appropriate symbol for the Latest Observations in your tracking layer, then you should be able to determine which observations are the latest.

   2. Check the Follow check box to automatically follow the entity you are monitoring. Every time a new observation is displayed for the entity, the map will automatically recenter on the latest position of the entity.
   3. To view a graph of an attribute for the tracked entity in real-time, select an attribute from the drop-down list at the bottom of the panel and click Start. A graph will be drawn as soon as another observation is displayed for the tracked entity.

      The graph will continue updating indefinitely. To stop graphing, click the Stop button.
