Abstract
An image that includes a point of interest is captured using an image capturing device that is part of the mobile data collection platform. Raw observables are obtained from a GNSS chipset that is internal to the mobile data collection platform. A position fix of the mobile data collection platform is determined based on the raw observables where the position fix defines a location of an antenna. A location of an entrance pupil is calculated as an offset of the location of the antenna. Orientation information comprising a tilt angle and an azimuth angle is determined. The position fix and the orientation information are associated with a three dimensional location that the mobile data collection platform is at when the image was captured. Scale information is captured. The image, the position fix, the scale information, and the orientation information are stored in hardware memory of the mobile data collection platform.
