Kitasato 1, Tsukuba, Ibaraki 305-0811, JapanGSI digitized the survey records and documents, which were recorded from Meiji era to early Showa era. Those records anddocuments include field notebooks, original draft result tables, calculation books and lists of survey results of baseline
measurement survey and triangulation survey. Those are very valuable information sources to study the history of modern
geodetic survey of Japan, as well as to understand the crustal deformation relating to the large earthquakes, such as Kanto
Earthquake (1923), based on the geodetic analysis. The digitized data, image files of the records and documents, are archived
into the file servers in GSI, from which users can browse the necessary ones.
