5.3 Development of Raster map 
revision system and utilization to 
mapping processes 
Map revision system based on raster image of a 
map was developed on an engineering 
workstation. After the test and examination on 
adapting it to actual map revision work, it 
became to be used for all the map revision work 
of 1:25,000 topographic maps conducted in- 
house in GSI in 1994. This system is also 
modified for 1:50,000 topographic maps which 
have slightly different map symbols and now 
used for revision work. 
5.4 Establishment of the International 
Steering Committee for Global Mapping 
Geographic information on global scale is still 
insufficient for increasing needs of such 
information required for coping with global 
environment problems. Based on an appeal of 
the Geographical Survey Institute and the 
resolution of the 1st International Workshop on 
Global Mapping held in Izumo, 1994, the 
International Steering Committee for Global 
Mapping was established and the 1st meeting 
was held on February 14, 1996. The outcome of 
the meeting is summarized as a resolution and it 
emphasizes to make existing data sets publicly 
available, national mapping organizations to 
assist in the development of missing global data 
set, and to get international recognition for the 
Global Mapping efforts as one of the positive 
activities toward addressing global concerns. 
5.5 Participation in the ISO/TC211 
activities 
Japan is participating ISO/TC211 activities as P- 
member (Participating member) and as project 
leader of two working groups for 
standardization of Geographic Information/ 
Geomatics.
