Geographic Information Systems, technologies behind

Geographic Information Systems (GIS) from a technical point of view. Spatial data models, topology, network operations, cartographic generalization, information theory and other elements that are behind a GIS. In a project work the students will be enabled to use some of this technology by development of a map-based application.

Knowledge

The student is supposed to have knowledge about

• Basic concepts for handling geographic information
• How to use Fuzzy Sets in connection with geographic information
• How to organize topological connections between geographic objects
• Technology for the portrayal of geographic information on the Internet
• Data structures for the representation of geographic information in various dimensions
• Important algorithms used in geographic information systems (GIS)
• Information theory and cartographic communication
• Techniques for cartographic animations
• 3D GIS and network analysis
• Quality and uncertainty in geographic information

Skills

The student is supposed to know how to:

• Choose the suitable data structure and use it for geographic objects
• Implement a map application (Web, pad, mobile unit) where elements from the discussed technology are used
• Make a map application that have 2-way interaction with a data base
• Make a map application, within a given theme, which has a carefully considered and good user interface
• Make a map application where the cartographic content is communicated in a good way and in accordance with the theory

General competence

The student is supposed to know how to:

• Handling geographic data in a computer
• Give a well considered presentation of geographic information in an electronic media
