Visualization of weather data on the Weather Information Exchange Model (WXXM) in geospatial systems using the visualization and colouring standard Styled Layer Descriptor (SLD)/Symbology Encoding (SE) is a rather unexplored area. In this thesis, a system named the Weather Client has been developed as a proof-of-concept prototype to evaluate said standards. Issues found during the implementation served as a ground for the evaluation and they were analysed in depth using a modified root cause analysis method. Each issue was evaluated with regard to functionality, usability, maintainability and efficiency. The result is a number of improvement proposals for the SLD/SE standard, an evaluation of the root cause analysis method as well as recommendations to Carmenta AB. The result of the evaluation indicated that the SLD/SE standard show great potential for describing weather data in geospatial systems. However, there are a number of issues that need to be resolved and further investigation is recommended.

Nyckelord: Styled Layer Descriptor, Symbology Encoding, Weather Information Exchange Model, METAR, weather visualization, map rendering, geospatial systems, root cause analysis, 5 Whys analysis method.
