Since -r3707 a virtual-measurement module is available in PALM. The module enables an easy setup of virtual measurements in the model domain emulating 'real-world' observations. Virtual measurement locations are placed within the model domain according to the UTM coordinates of the 'real-world' observations. This way, not only point and profile measurements can be emulated in the model, but also complex trajectories such as spiral-shaped flight measurements or bicycle/pedestrian measurements. 

Documentation will be continued ...

-not possible with masked data output
-measurements are taken along the entire trajectory. 
-static is required, georeferencing.
