In addition to the summary operations described above, exact_extract can accept an R function to summarize the cells covered by the polygon. Because exact_extract takes into account the fraction of the cell that is covered by the polygon, the summary function must take two arguments: the value of the raster in each cell touched by the polygon, and the …
Читать далееexactextractr. exactextractr is an R package that quickly and accurately summarizes raster values over polygonal areas, commonly referred to as zonal statistics.Unlike most zonal statistics implementations, it handles grid cells that are partially covered by a polygon. Despite this, it performs faster other packages for many real-world applications.
