Abstract
External accessory data is collected at a mobile data collection platform provided by an external accessory of the mobile data collection platform. An image that includes a point of interest is captured by an image capturing device that is an integral part of the mobile data collection platform performs. Raw observables are obtained from an external GNSS raw observable provider that is separate from and outside of the mobile data collection platform. A position fix of the mobile data collection platform is determined based on the raw observable. Orientation information comprising a tilt angle and an azimuth angle is determined. External accessory data is received from an accessory that is external to the mobile data collection platform. The image, the position fix, the orientation information and the external accessory data are stored in hardware memory of the mobile data collection platform.
