This read-only value, in meters, reports the altitude returned by the GPS device during its last location fix, ranging from -500 to 500 meters. An admin uses this for applications where elevation matters, such as distinguishing a device on a rooftop from one at street level, but should first check c3gLbsHeightValid before trusting the figure. For example, if a vehicle-tracking deployment expects the device to remain near sea level but this height reading suddenly jumps significantly and c3gLbsHeightValid is true, the admin might investigate an unexpected elevation change.
