Detected AR-Markers in the [[POI_View|POI View]] having this Classification will be used to calculate the device position and orientation (see [[AR-Marker Device Pose Estimation]]).

The GEO property defines the position of the AR-Marker within the WGS-84 world coordinate system. The rotation properties define the AR-Marker orientation in relation to the shown local coordinate system. Per default (and if all rotation properties are 0) the AR-Marker´s and local coordinate system´s axis are aligned. Rotations are applied in following order: z-y´-x´´. That means for example, that the y-rotation is applied after the rotation around the z-axis was performed.
