Claim:
1. A method of performing data collection using a mobile data collection platform, the method comprising: capturing an image that includes a point of interest, wherein the capturing is performed by an image capturing device that is an integral part of the mobile data collection platform; obtaining external raw observables from a Global Navigation Satellite System (GNSS) raw observables provider, wherein the GNSS raw observables provider is external to and coupled with the mobile data collection platform; determining a position fix based on the external raw observables, wherein the position fix defines a location of an antenna associated with the GNSS raw observables provider; calculating a location of an entrance pupil of the image capturing device as an offset from the location of the antenna; determining orientation information comprising a tilt angle and an azimuth angle of the mobile data collection platform, wherein the position fix and the orientation information are associated with a three dimensional location of the mobile data collection platform when the image was captured; capturing scale information; capturing angular displacement from a first point on a scalar reference to a second point on the scalar reference visible in the image as given by a pixel count from the first point to the second point; and storing the image, the position fix, the scale information, and the orientation information in hardware memory of the mobile data collection platform, wherein the capturing, the obtaining, the determining of the position fix, the calculating, the determining of the orientation information, and the storing are performed by one or more hardware processors that are part of the mobile data collection platform, and wherein the one or more hardware processors are outside of an internal GNSS chipset of the mobile data collection platform.
