Abstract:The aerial triangulation data is used to provide orientation framework data for photogrammetry.Thus the quality of aerial triangulation data impacts the quality of final products.Combing the actual problem confronted in the production practice,the authors discussed the 3 key links to improve the quality of aerial triangulation results,including field control surveying,indoor control points measurement,and the residual error analysis of field control points and the inspection and assessment of aerial triangulation results.
Keywords:aerial triangulation  reliability  unique  consistency  rationality  regional network
