Medium format cameras for mapping – analisis of productivity for orthophoto production

Abstract

ABSTRACT: The paper presents a productivity comparative analysis of PhaseOne cameras and two other main groups of cameras widely used in the mapping market. Analysis was carried out in comparison with UltraCam Eagle and Leica DMC III referring to flight mission parameters influencing on productivity. The analysis was conducted with various spatial resolution of images in the context of creating final orthophotomap for urban areas, taking into account the influence of the center projection on the appearance of buildings. The time of the flight missions was also analyzed. In the presented studies, it has been proven that, on the example of PhaseOne cameras, a medium format camera can be less expensive and effective alternative for large format cameras for small and medium size urban and rural mapping projects.
