Fast rasterize in r. fasterize is a high-performance replacement for the rasterize() function in the raster package. Functionality is currently limited to rasterizing polygons in sf -type data frames. From my experience, gdalUtils is actually faster than raster, even when using fasterize. Cochran. For polygons, values are transferred if the polygon covers the center of a raster cell. Fast polygon-to-raster conversion, burn polygon shapes and/or values into pixels. The algorithm is based on the method described in course materials provided by Wayne O. Nov 29, 2019 · Have you considered the R "gdalUtils" library?
