GPS Map

The GPS map view displays GPS tracks in a map that are constituted of the measure signals latitude and longitude. It is very useful if you want to put geographic data providing street and terrain information in relation to other measured signals. Thus, any abnormal behavior in the engine module under test can be analyzed in a better way if the GPS data like longitude and latitude are considered during the offline analysis.

Additionally, you can add an indication signal, for example the velocity, either as a Boolean signal or as an analog signal. In case of a Boolean signal, the color of the track changes depending on the state of the Boolean signal. In case of an analog signal, the track is displayed with a color gradient.

MDA uses a license-free open-source street map.

To see how you can create a GPS Map instrument, use the zoom and scroll functions, and synchronize the GPS Map with other instruments, watch our video Using the GPS Map.

Since V8.8, if the GPS Map Instrument type that is used to display GPS data (i.e. GPS tracks constituted of the signals latitude and longitude) in a map. instrument displays only a blue field instead of the expected map and a warning error appears, the download is blocked by the Windows Defender Firewall. To load the required map content, the following releases in the customer firewall are needed and should generally be unblocked by the customer IT department:

• Release of port 443 (over HTTPS)
• URL: maps.omniscale.net.

You can perform the following actions:

• To define the GPS Map properties
• To add a signal
• GPS Map
• To define the color of a track based on an indication signal
• To add an Event signal
• To zoom
• To zoom to show the complete track
• To select a specific time range of the track
• To show cursors
• To delete a signal

To define the GPS Map properties

The complete set of configuration possibilities for this instrument is available in the Properties docking window. There, the tooltips provide a detailed description of the properties and their possible options.

1. Do one of the following:

   • In the instrument, click .

     or

   • Select the instrument and press Alt+Enter.

     or

   • In the instrument, right-click and select Properties in the context menu.

To add a signal

1. Select a latitude and a longitude signal from the Variable Explorer or the Configuration Manager.

2. Drag and drop the signals onto a layer or layer tab of the configuration and select the GPS Map instrument. For more information, see To assign signals to a new instrument.

   The map view appears and the track is displayed.

   V8.8 tries to assign automatically the signals to the correct coordinates by checking for "long" respective "lat" in the signal names. If the automatic signal assignment is incorrect, switch their assignment by clicking on .

To define the color of a track

1. Click the color icon of the respective track.

2. Select the desired color.

To know how you can assign a color to a specific file, see Defining one Color per File.

To define the color of a track based on an indication signal

To see sections of the track which fulfill a specific condition, you can color the track based on an indication signal.

The color of the indication signal will overrule the track color and a potential color definition for the measurement file.

1. Create a track in a GPS map instrument as described under To add a signal.

2. Select a third signal and add it to the entry in the track list of the GPS map instrument.

3. Depending on the type of signal, the color coding can be defined in the track list of the GPS map instrument.

   Two distinct colors can be defined. This leads to a change of color or to a color gradient of the track for Boolean or analog signals, respectively.

   Note
   Only Boolean and analog signals can be used as indication signals, but not for example enumeration signals.

To add an Event signal

When adding event signals to a GPS map, the location where an event occurred is indicated by .

If several tracks are displayed, for a unique identification the color of the icon has the same color as the track. The color of the flash inside the icon represents the event type (e.g. pause event, comment event, calibration activity, etc.).

To zoom

Do one of the following:

1. To zoom in, click .

2. To zoom out, click .

   or

1. Use the mouse wheel to zoom in or out.

To zoom to show the complete track

1. Click , and the map will be zoomed that the track is completely visible.

To select a specific time range of the track

1. To see which track was driven during a specific time range, the Time Slider is used. For more information, see Time Navigation and Synchronization.

   When only a sub-time range is selected, this track is shown in dark blue, while the track outside this time range is indicated in light blue.

To show cursors

In synchronized mode, cursors are shown as these are given by the master instrument. Cursors can be moved directly in the GPS Map instrument or follow the cursor's movement in the master instrument.

To delete a signal

1. Open the Configuration Manager and delete the respective signal from the GPS Map view.

   or

1. In the GPS Map instrument, right-click the signal and select Remove Track(s).

   or

1. In the GPS Map instrument, click the signal and press the Del key.
