In this paper,based on the theoretic accuracy analysis of large scale photogrammetric mapping,some defects in traditional procedure were discussed;a set of key technology dedicate to the low altitude photogrammetry was described in detail,including selecting the wide angle camera,lower flight,enhanced image matching,the field distribution of measuring mark point,preferably adjustment model,and refined mapping operation.Then, a low altitude aerial unmanned airship system was established.Finally,the proposed method was verified through the production practice of 1∶500 DLG surveying and mapping in 30 counties in Shanxi province.
