About "standardization," "Japanese Standards for Geographic Information (JSGI)” is established as a
standard of the national government. Globally, formulation of standardization of geographic information is
carried out in the ISO/TC211 about items more than 40. In Japan, as a results of joint research with private
sectors, GSI made JSGI as standards in Japan based on ISO about basic standard 13 items such as application
schema, spatial reference, encoding, data quality and meta data (specifications of data), to be necessary for
smooth exchange of data. Each items of JSGI become Japanese Industrial Standards (JIS), as soon as an
international standard is settled in ISO. Geographic information complying with JSGI includes the following,
among others: Digital Map 25000, Digital Map 2500, Spatial Digital Information, and Residential block level
Location Reference Information. In addition, to promote use of standards, GSI developed the Japan Profile for
Geographic Information Standards (JPGIS) in March 2005, as a practical profile of JSGI.
