A system that facilitates determining a trigger rate for a digital camera to provide a threshold forward overlap for consecutively captured images is described herein. The system includes a receiver component that receives first data pertaining to a distance between the digital camera and a surface. The system additionally includes a rate determiner component that is in communication with the receiver component, wherein the rate determiner component determines the trigger rate for the digital camera based at least in part upon the first data, wherein the trigger rate is indicative of an amount of time between consecutive images captured by the digital camera.
