spplot,AQuadtree-method

spplot

Provides an automatic aggregation tool to manage point data privacy,
intended to be helpful for the production of official spatial data and for researchers.
The package pursues the data accuracy at the smallest possible areas preventing
individual information disclosure. The methodology, based on hierarchical geographic
data structures performs aggregation and local suppression of point data to ensure privacy
as described in Lagonigro, R., Oller, R., Martori J.C. (2017) <doi:10.2436/20.8080.02.55>.
The data structures are created following the guidelines for grid datasets from the
European Forum for Geography and Statistics.
