Objectives and Contextualisation
This optional module, increases the knowledge acquired in the spatial analysis module of the same master, focusing on the exploitation of geographic databases from the SQL language, as well as in specific practical cases. In addition, it adds concepts associated with the publication of cartography on the Internet taking into account international standards for data and metadata that allow interoperability including semantic, technologic, information, etc.
At the end of the course, the student will be able to:
1. Use different cartography publication tools on the Internet.
2. Know the advantages and limitations of the use of standards in the GIS world.
3. Apply international standards to the edition and publication of data and metadata on the Internet.
4. Master queries in databases using SQL language.
5. Design appropriately information systems for the use of data in a scientific, professional or informative context.
