In jcheng5/rasterfaster: Fast operations for Raster objects

rasterfaster

This package is intended to provide faster but potentially less general/flexible raster operations than are available in the raster package itself. One of the primary goals is to enable near-realtime exploration of large raster data files with Leaflet.

Features

1. Resampling (nearest neighbor and bilinear)
2. WGS84 to Web Mercator projection, and map tile extraction

Currently only .grd files (as created by raster::writeRaster) with numeric data are supported.

Don't even think about using this package for any real analysis yet.

Usage

r <- raster("yourfile.grd")
plot(resampleBy(r, 2.3))  # 2.3X larger
plot(resampleTo(r, 90, 180))  # 90 rows by 180 columns
createMapTile(r, 256, 256, xtile = 2624, ytile = 5719, zoom = 14,
  projection = "epsg:3857", method = "auto")

Installation
