Abstract
External accessory data is collected at a mobile data collection platform (MDCP) provided by an external accessory of the MDCP. An image that includes a point of interest is captured using an image capturing device integral to the MDCP. Raw observables are obtained from a GNSS chipset internal to the MDCP. An position fix of the MDCP defines the location of an antenna and is determined based on the raw observables. An entrance pupil location is calculated as an offset off the antenna location. Orientation information comprising a tilt angle and an azimuth angle is determined. The position fix and orientation information are associated with a three dimensional location that the MDCP is at when the image was captured. External accessory data is received from an accessory external to the MDCP. The image, position fix, orientation information and external accessory data are stored in hardware memory of the MDCP.
