Webt = photo tilt angle c. The tilt of aerial mapping photography is seldom large enough to require using tilted photograph equa-tions for hand calculations when planning and estimat-ing projects. However, Equation 10-8 does show that scale is a function of tilt, and scale variation occurs on a tilted photo even over flat terrain. d. WebSep 16, 2024 · What is overlapping in aerial photography? Overlap: is the amount by which one photograph includes the area covered by another photograph, and is expressed as a percentage. The photo survey is designed to acquire 60% forward overlap (between photos along the same flight line) and 30% lateral overlap (between photos on adjacent flight lines).

WebFORWARD OVERLAP. To ensure complete coverage of the area, you should take each photograph in each flight line or strip so it overlaps both the preceding photograph and the following photograph. The amount of overlap on each photograph is approximately 60 percent. Creating this overlap ensures that the strip contains no blank areas (fig. 4-17). WebThe air base (í µí°µ ) has the following relationship with aerial photography flight speed (í µí±£ ) and photography interval (í µí±¡ ) (3). í µí± refers to the overlapping of ...
