GeoDI Progress Meeting 3

difficulties
Difficulties
  • Data Modelling
    • Data complexity (relationships)
    • Data heterogeneity

 Need to design a model that supports all the types of information available in the existing datasets

    • “Many” options for modelling

 Selected option that “makes the most sense”

    • Domain knowledge

 Support from CMRC experts (Max Kozachenko & Gerry Sutton)
