6. Perspectives in future 
ISCGM adopted at the third meeting the above-mentioned technical 
specifications, but these specifications should be improved 
continuously. Further development of the detailed specifications are 
bound with no contradiction to other geographic data 
standardization, especially to the ISO/TC211. Participation of 
various organizations in this project will be further needed for the 
actual data set preparation. Although diverse tasks are existing in 
undertaking this project, not only in data preparation but also in 
effective data utilization, we will do our best to concentrate much 
wisdom for this project.
