Abstract of si 3 co project and architecture of test bed

Purpose of SI3CO Project

■ Develop the Japanese domestic test-bed system base on the OGC’s 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.

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
