Split a raster grid into tiles for tile-based processing
Split a raster grid into tiles. The tiles are saved as Rsagacmd temporary files, and are loaded as a list of R objects for further processing. This is a function to make the the SAGA-GIS grid_tools / tiling tool more convenient to use.
tile_geoprocessor(x, grid, nx, ny, overlap = 0, file_path = NULL)
x |
A 'saga' object. |
grid |
A path to a GDAL-supported raster to apply tiling, or a RasterLayer. |
nx |
An integer with the number of x-pixels per tile. |
ny |
An integer with the number of y-pixels per tile. |
overlap |
An integer with the number of overlapping pixels. |
file_path |
An optional file file path to store the raster tiles. |
A list of RasterLayer objects representing tiled data.
