Description

This package provides an S4 class for creating, manipulating and exporting spatial quadtree varying size grids, and for methods including print/show, plot, spplot, subset, [, [[, \$, names, dim, summary, writeOGR.

Introduction

The quadtree functions and class provide the tools to build a varying size quadtree grid performing a bottom-up aggregation considering a minimum threshold for each the cell. The main goal of the package is the anonymization of a set of spatial point data by an aggregation process as in a k-anonymity model. The grid created follows the INSPIRE Specification on Geographical Grid Systems.
