- 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
- 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.
- 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.
