tilework: Extensible Tile Planning and Windowed Parallel Processing
An extensible framework for tile-based processing of large, spatially indexed data. Tile plans are first-class objects describing a set of bounds, which may be regular grids in pixel or coordinate space, tiles centered on supplied points, or adaptive decompositions such as quadtrees. Bounds may carry padding, supplying the overlapping context that neighborhood operations and objects spanning several tiles require. Extraction dispatches on the class of the input, so one plan can window two data sources of differing type together; methods are provided for 'terra' rasters and vector proxies, and other packages can register methods for their own formats. Tiles are processed in parallel through 'future', or optionally 'BiocParallel', and a per-worker initialization step amortizes expensive setup such as loading a model.
