The image data format in lunar explorations
Li Chunlai · Progress in geophysics · 2006
Lunar imagery data are significant resource in lunar scientific researches.In earlier lunar explorations such as lunar orbiter,Apollo and Surveyor missions,the imagery data were transmitted to Earth as analog data and were scanned for distributing.Images were usually saved as photos to distribute to users.In Clementine programs,the data are transmitted to the PDS node,and PDS center are responsible for organization and distribute of the data.Several principles should be applied in saving and distributing imagery data.One is the imagery data can be renewed and extended continuously.The other is the data can be expediently used in different platform and are available for not only scientific organization but also general interested user.In addition to above this,the data format should be coordinuted with international data format organization standard to conveniently manipulate and manage.We table a proposal for imagery data format in Chang'er project.
