Objectives

  • Tests on different ways to compare maps
  • Compare maps from same original data on which different SDC methods have been applied
    • methods in mind: multilevel grids / CKM / Swapping

Distances/Metrics

  • One based on comparison of Moran's I
  • Kullback-Leibler (based on Entropy)
  • The most relevant one seems to be the Kantorovitch-Wasserstein Distance implemented in the Spatial_KWD package.

TODO

  • build a microdataset
  • prepare microdata for ckm (key to individuals)
  • compute grid data on 1km squares grid:
    • original data
    • perturbed data with CKM
    • perturbed data with multilevel grid method
  • compare the utility of the different solutions with the KW distance.
