  5. Caracteristics of the Mutual Utilization System comforming to the standard I/F Unique I/F Standard I/F Formation of data communication infrastructure & Expansion of applications System A System C Stan- dard I/F System B System D Counterpart System Own System WWW/ LAN Non- Mutual Type Close Combination (Unique Architechture corresponding to the Counterpart System) Estranged Combination （Independent to the structure of the Counterpart System. Easy to mutually connect distributed system.) WWW Mutual Type :Coverage to be known by System developer *Standard I/F: ex.＞in case of WMS (Web Map Server) GetCapabiliteis (meta data distribution) rules GetMap (image data distribution) rules

  6. Access to the Mutual Utilization System Agents（Portal Sites） Geographic Information Standard Service Provider A End Users Service Provider B Service Provider C （Future） Directory Retrieval Retrieval Meta data Registration Meta data distribution Request for Services Provision of Services （Future: End users utilize services without consciousness of distributed servers） ・・・

  7. Benefits of Adoption of Standard I/F Adoption of Standard I/F Various databases can easily connect and collaborate with each other Users can utilize satellite data in combination with other data Users can enjoy active handling such as expansion/reduction, superimposing, thematic map generation with only browser instead of special applications for experts. Satellite data becomes more attractive and more utilized
