| This study examines the viability of using Digital Frame Camera (DFC) imagery for producing digital ortho-images. Municipal staff in the Town of Smiths Falls, Ontario, Canada are interested in establishing alternative methods for collecting geo-spatial data that are cost effective and operationally feasible. Other small municipalities face a similar challenge.; Stereo airborne DFC imagery was acquired from a small aircraft over Smiths Falls. In order to determine the base accuracy level achievable with minimal investment, camera position and attitude were not measured or controlled in flight, nor was the camera calibrated. Instead, sub-metre differentially corrected Global Postioning System (DGPS) data were used for control and test purposes. Ortho-image and DEM accuracies of 1.07 m RMSE (1.85 pixels) and 7.25 m (12.5 pixels), respectively, were observed using DGPS and digital map data as a reference.; The thesis presents a discussion of the potential applications of such ortho-imagery for small municipalities. |
