Activities for Developing Global Map Version 3 Data

摘要

Global Mapping Project aims to develop basic geospatial data covering the whole land area of the globe through international cooperation of National Mapping Organizations (NMOs) around the world. The objectives of the project are to contribute to global issues.Global Map Version 1 was released in 2008. Currently, Glo bal Map Version 2 data development is almost completed with the collaboration of the project participating NMOs aiming to be completed in March 2013. From April 2013, development of Global Map Version 3 was started. Global Map can be applied to many fields, such as flood analysis and infrastructure development. However, the existing data at a scale equivalent to 1 to 1 million do not include detailed road and village information. Currently, specifications are under di scussion for the development of Global Map Version 3 data by incorporating user needs to make Global Map data more usable. Geospatial Information Authority of Japan (GSI), the NMO of Japan, in charge of the secretariat of International Steering Committee for Global Mapping (ISCGM) is actively supporting the data development by preparing a data development manual and other useful tools pursuant to the new specifications.
