phototheodolite การใช้

The device was based on the prototype phototheodolite developed by Albrecht Meydenbauer ( 1834-1921 ) for architectural applications.
Returning to Joshimath he took up a phototheodolite and went south to survey the Rinti glacier and the saddle between Trisul and Nanda Ghunti.
The addition of a camera to the plane table, as was done from 1890 by Sebastian Finsterwalder in conjunction with a phototheodolite, established photogrammetry in spatial and temporal surveying.
He applied the technique of plane table photogrammetry in addition to a conventional geodetic survey, assisted by the novel lightweight, accurate phototheodolite that he had developed for high-mountain applications.
Knowing of Shipton's 1934 explorations, Gordon Osmaston, director of the Survey of India's triangulation of Great Himalaya, planned to improve the survey of the Sanctuary using a phototheodolite.
