Geographic Databases and Geospatial Web Services


This course focuses on: (a) the Object-relational database technology in handling geographic data, and (b) the geospatial web services in sharing and visualizing the database content over the Web. This curricular unit builds on the Geospatial Databases course, where the recent dynamics in spatial databases were introduced. 

Through the course project, students will learn how to create and populate a geographic database in Postgres/PostGIS database management system. Special attention will be given in querying the database content based on spatial and non-spatial predicates. Furthermore, students will get acquainted with and develop basic OGC services for mapping to share and visualize the geographic database content over the web.
