7 Google Earth server
This section gives an overview of the Google Earth server support in u-center.
The Google Earth server can continuously send positioning data in a specific format to the Google Earth
application. By hosting such a server in u-center we are able to visualize positioning data in real time.
There are only a few settings that can be set via the Google Earth server dialog. This means a lot of functionality
and behavior of the Google Earth is still configurable from the application itself and therefore out of control of
u-center's direct control.
Perform the following steps to start the Google Earth server:
1. Establish the communication between u-center and the device (see also Connect to the receiver).
2. Open Google Earth settings dialog by clicking on File -> Database Export -> Google Earth Server...
Figure 50: Google Earth settings dialog
3. Enter the port of the server. See position a.
4. Select the refresh mode. Supported modes are "On camera stop" where Google Earth will send requests only
when previous view has stabilized or "On interval" where requests from Google Earth will be sent in regular
intervals. See position b.
5. Enter the refresh time. This is the time between two consecutive requests in "On interval" mode or delay after
camera stops in "On camera stop" mode. See position c.
6. Enter the altitude in meters of the view. See position d.
7. Enter the tilt in degrees of the view. A value of 0 indicates that the view is aimed straight down toward the
earth and a value of 90 indicates that the view is aimed toward the horizon. See position e.
8. Check this field if you want the heading of the camera to follow heading information coming from UBX-NAV-
PVT message. See position f.
9. Enter the number to set the line width in the view. Higher values mean a thicker tracking line. See position g.
10.Select the altitude mode for the view. The "absolute" mode sets the altitude relative to sea level,
"relativeToGround" mode sets it relative to the actual ground elevation in a particular location and
"clampToGround" ignores the altitude specification. See position h.
11.Click on "Update preferences" if you want to permanently store information about Line width and Altitude
mode. The same can be achieved through menu "Tools->Preferences->KML settings". See position i.
12.Click on "OK" to start the server.
