 = Ground truth
 
-Ground truth describes the simulated environment around all simulated host vehicles in a global coordinate system.
-Ground truth provides an exact view on the simulated objects in a global coordinate system.
-It is based on internally available data and published to external subscribers.
-Depending on the external subscriber, ground-truth data may be individually restricted.

-//TODO: It looks like we may have two conflicting descriptions here.
-// I cannot tell which one is correct or if they are conflicting at all.
-// The first sentence is based on the comments in the proto files.
-// The second sentence is based on the description on Github pages.

 = Sensor data
 
 Sensor data imitates the output of real sensors.
-It is generated from ground-truth data, feature data or from sensor data.
+It is generated from ground-truth data, sensor-view data, feature data or from sensor data.
 All information regarding the environment is given with respect to the virtual sensor coordinate system, except for feature data, which is given with respect to the physical sensor coordinate system.
-Sensor data can be used as input of an automated driving function,  a sensor model simulating limited perception, or a sensor fusion model.

 All information regarding the environment is given with respect to the virtual sensor coordinate system, with two exceptions:
 
-* Individual physical technology-specific data, given with respect to the physical sensor coordinate system specified in the corresponding physical sensor’s mounting position
-* Ground truth data, given in global coordinates.
