This lecture aims at introducing the technical foundation for evolving service-oriented (geographic) information architectures driven by SDIs. The students will learn organizing spatial data in object-oriented databases, manipulate and query the data as well as making this information available in geospatially enabled distributed service architectures. The key components of SDI and Web GIS will be reviewed: - organizing and sharing GI resources - understand the principles and techniques of spatial data organization and apply these principles and techniques to design and build spatial databases (e.g. Oracle Spatial, Postgres PostGIS, ArcSDE etc.); - understand the concept of spatial data infrastructures; give examples of organizing spatial information in geoportals at organizational, enterprise, national, regional and global levels (e.g. ArcGIS Online) - publishing GI content and tools over the web: map services, data services, and analytical services; (e.g. ArcGIS Server, Geoserver Open Source) - discuss and define the interoperability needs beyond technical issues like direct access and industry standards on a legal, semantical and organizational level
