  5. Background :Why Component Software? • Software crisis in the age of information • Lack of Interoperability • Lack of Reusability Software Crisis Information Software Technology Component Software is a Solution

  6. COMPONENT Open GIS Component GIS STANDARDS GIS TECHNOLOGY Open GIS Component

  7. OGC • The OGC is an open forum for the GIS community to contribute to the interoperability in geodata and operations(Buehler et al, 1996) • Since 1994 • More than 20 SIGs /WGs • 16 Abstract Specifications • Central themes • Sharing Geospatial Information • Providing Geospatial Services • 7 Implementation Specifications • Legal liaison with ISO/TC211

  8. ISO/TC211 and OGC • Cooperative agreements • ISO 19125 Geographic information – Simple feature access is based on the OGC OpenGIS Simple Features Specification • 19125-1 Part 1: Common architecture • 19125-2 Part 2: SQL option • 19125-3 Part 3: COM/OLE option • ISO 19128 Geographic information – Web Map server interface • OGC Web Map Server Specification • ISO 19132,19133,19134 Location Based Service • OGC OpenLS Architecture

  9. Simple Features Specification for OLE COM • OLE/COM based proposal • 3 Main Themes • Data Access Architecture • OLE DB based Data Providers and Data Consumers(ADO) • Geometry Object Model • Geodata modeling • Geodata Operations • Spatial Reference System Object Model • Datum Definition • Transformations • Projections • Component Specifications
