Geographic Information Systems (GIS) allow for the storage, analysis, and visualization of spatial information about the real world. Due to the enormous amount of data that geographic software must be able to manage, it is essential to have algorithmic techniques and efficient data structures specially designed for this type of information. In this course, a selection of fundamental topics for the development of algorithms for geographic information systems will be presented. The selected contents will be introduced in the context of real applications, followed by the presentation of advanced computer techniques that provide efficient solutions to these geographic problems.

Teaching methodology

The course will consist of presentations of the main theoretical topics, followed by a discussion of the more practical aspects associated with them, and the presentation of practical tools to address them.

Evaluation methodology

Evaluation will be based on a final project that will consist of theory and bibliography research tasks about a concrete GIS problem, and in class participation.
