On the Large-scale Topographic Map Produce with Small Format Non-metric Camera Airphotos

  • The large-scale topographic map first produced by small format non-metric camera airphotos taken in the light aeroplane is discussed. The approaches that how to make use of enlarged photos,and how to over come the difficult from very large dip angle and the systematic error caused by film unfiattenness are presented in sequence. It is proved by experiments that small format airphotos can be used to produce large scale topographic map. The map precision according to the demands of mapping standard.
