An R package for anonymisation of spatial point patterns and raster objects.
This package achieves the relatively simple, yet useful, task of spatial anonymisation. Anonymisation is needed in situations where a data owner may not wish to share the actual spatial locations of their data, but is happy to share transformed data in a way that still permits valid spatial analysis.
Anonymisation is achieved via three modes of spatial shifts:
The tangles package can entangle both non-gridded
spatial point patterns and raster objects. It can also entangle data
using a pre-defined entanglement sequence and can disentangle data back
to their original spatial representations. Each entanglement process is
given a unique hash key label to guarantee successful restoration of the
original spatial structure.
Install the development version of tangles from GitHub
using the devtools package:
# Install devtools if you haven't already
install.packages("devtools")
# Install tangles
devtools::install_github("brendo1001/tangles")
