Purpose of SI3CO Project
■ Develop the Japanese domestic test-bed system base on the OGC’s interoperable 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 testbed 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.

Plan of Spatial Data Modeling Group
Plan and Proposal of Spatial Data Model:
■ Inspect international standard specifications
■ Inspect domestic GIS standard specifications
Create Base Model:
● Feature Model
Describe semantics, geometry, and properties of vector typed data
● Coverage Model:
Describe semantics, geometry, and properties of raster typed data
Create Application Model:
● Disaster prevention community model
● City planning community model
● Water supply and swage community model
● Common model
Plan of Distributed-Spatial-Object Technology Developing Group
Verification of interoperable
GIS:
■ Verify the interoperable system
based on the the OGC spec.
■ Develop domestic interoperable
test-bed system
