1.The purpose of establishment of JAS

Following the enactment of the Land Survey Law in 1949 and the creation of national qualifications for registered surveyors and assistant registered surveyors, the Japan Association of Surveyors was founded in 1951 as an organization for survey technicians active in Government, Academia and Industrial Corporations and interested in joining together in a professional body whose aim is to contribute to dissemination and advancement of surveying technology and to enhance mutual friendship among, and the social status of, its members. The Association is a nonprofit organization approved by the Ministry of Land, Infrastructure and Transport (former the Ministry of Construction).

3. JAS Major Activities

The Association publishes the Journal of Survey (a monthly journal) as well as other technical books in geoinformatics, sponsors survey and design system exhibitions and provides training and study courses to survey technicians and researchers. The Association engages in activities to earn revenue by offering services to calibrate surveying instruments, examine survey data obtained as survey results, provide consulting services to clients such as survey planning organizations and deliver the real-time electronic control point data. The Association has established a surveying technology promotion fund and awards its Survey Technology Promotion Prize every to outstanding survey technicians and researchers among its members for the promotion of surveying technology.
