Purpose of SI3CO Project
Develop the Japanese domestic test-bed system
base on the OGCs inter- operable interface
specifications ? Confirm the possibility of
the practical construction of sensitive system by
utilizing Japanese high resolution
maps ? Propose the high level
specifications such as a semantic compensation
when user want to utilize the high
resolution maps Grasp a concrete needs though
the practical test and evaluation of the test-
bed system in the typical place of Japan
? Extract concrete needs by evaluating as the
fundamental part of GIS which is utilized
as the common GIS in a municipal government.
