Package: quadtree 0.1.14
Derek Friend
quadtree: Region Quadtrees for Spatial Data
Provides functionality for working with raster-like quadtrees (also called “region quadtrees”), which allow for variable-sized cells. The package allows for flexibility in the quadtree creation process. Several functions defining how to split and aggregate cells are provided, and custom functions can be written for both of these processes. In addition, quadtrees can be created using other quadtrees as “templates”, so that the new quadtree's structure is identical to the template quadtree. The package also includes functionality for modifying quadtrees, querying values, saving quadtrees to a file, and calculating least-cost paths using the quadtree as a resistance surface.
