Implementation tests and utilization manuals based on Japanese Standards for Geographic Information (JSGI)

In Japan, the Geospatial Information Authority of Japan and private companies have jointly created and updated the Japanese Standards for Geographic Information (JSGI) in accordance with several ISO 19100 series standards in the draft stage to arrange implementation tests and utilization manuals.
This joint research mainly covers the following standards related to creation and exchange of spatial data:

- ISO 19107 Spatial schema
- ISO 19108 Temporal schema
- ISO 19109 Rules for application schema
- ISO 19110 Methodology for feature cataloguing
- ISO 19111 Spatial referencing by coordinates
- ISO 19112 Spatial referencing by geographic identifiers
- ISO 19113 Quality principles
- ISO 19114 Quality evaluation procedures
- ISO 19115 Metadata
- ISO 19117 Portrayal
- ISO 19118 Encoding

Several results have been yielded, and have widely been released to the public in Japan. This time, we decided to create and release the English version of reports that also provide other countries with useful information.

Note The following reports, some of unimportant terms may remain in Japanese or have no supplementary explanation. It should be disregarded although an font error and character transformation when a PDF file is opened.

1) Spatial Data Exchange Tests Based on Japanese Standards for Geographic Information (JSGI)

In spatial data exchange tests, an application schema for spatial data was actually designed, XML format data based on ISO 19118 was created, and multiple GISs were used to exchange data and portrayal information based on the specifications in the Japanese Standards for Geographic Information (JSGI). Through this exchange tests, the practicability of the specifications themselves in the standards was confirmed, the method for defining an application schema and actual examples of encoding the application schema were provided, and the notes to consider for actual operation were extracted.

In line with these spatial data exchange tests, the Geospatial Information Authority of Japan has designed application schemas for major features within a 1:25,000 topographic map and has formally published the XML-encoded dataset since October 2001.

2) User's Manual for Spatial Data Product Specification Description

User's Manual for Spatial Data Product Specification Description is created to spread the standards based on ISO/TC211 in Japan. This manual assumes that national organizations, local public organizations, and private companies use the ISO 19100 series standards, and has the purpose that is different from that of ISO19131 Data Product Specifications. However, in order to help consider creating the standard for data product specifications or use the ISO 19100 series standards in countries, this English version is created.

3) Japanese Core Metadata Schema

Japanese Metadata Profile 1.1a (JMP1.1a) was developed based on 1st CD of ISO19115 under this joint research project and used for clearinghouse activities. Then revising the JMP1.1a was frozen during CD stage in ISO/TC211. After entering DIS stage, ISO19115/DIS was carefully checked in the project. We found that there were many errors in ISO19115/DIS caused by mainly harmonization problems between ISO19115 and other standards in ISO19100 series. Especially core metadata was not well defined. We amended the document and created following UML class diagrams of core metadata.

ISO/TC211 resolved to correct minor technical improvements for FDIS. Even though the schema may not reflect on ISO19115/FDIS, it will useful for users who will try to use core metadata.

Update information: JMP2.0 was developed based on ISO 19115 in 2003. Metadata was converted from JMP1.1a to JMP2.0. (JMP2.0 UML)
