    • Topics:

      extracting information from (big) data for decision support
      concepts of adding value from data to information to knowledge
      selection and aggregation
      pattern and structural analysis: PPA, landscape metrics, ...
      distance based analyses, incl allocation
      spatial interpolation
      multithematic analysis and decision support, GeoPlanner

    • Learning objectives (module level):

      • understand the objective of spatial analytics to create information for decision support from data, by exploring patterns, relations and context
      • apply exploratory data analysis techniques to detect any underlying spatial organisation 
      • create analytical workflows from individual methods and techniques aiming at answering specific questions and solving problems
      • select adequate spatial analysis approaches based on generic concepts and data characteristics
      • automate analytical workflows for pattern detection and knowledge extraction 
Distance based analysis
Surface / terrain analyses

    • Learning objectives: 

      • understand spatial autocorrelation as a fundamental characteristic in spatial organisation of phenomena, including the tenet of Tobler's first law of Geography
      • apply suitable methods to distinguish between random and clustered distributions of locations and observations
      • select adequate interpolation techniques depending on scale level, sample distribution and spatial variation
      • make informed choices for IDW parametrization and assess quality of interpolation results
