tile_geoprocessor: Split a raster grid into tiles for tile-based processing

In stevenpawley/RSAGA5: Linking R with the Open-Source 'SAGA-GIS' Software

Split a raster grid into tiles for tile-based processing

Description

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.

Usage

tile_geoprocessor(x, grid, nx, ny, overlap = 0, file_path = NULL)

Arguments

x	A 'saga' object.
grid	A path to a GDAL-supported raster to apply tiling, or a SpatRaster.
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.

Value

A list of SpatRaster objects representing tiled data.

Examples

## Not run: 
# Initialize a saga object
saga <- saga_gis()

# Generate a random DEM
dem <- saga$grid_calculus$random_terrain(radius = 15, iterations = 500)

# Return tiled version of DEM
tiles <- tile_geoprocessor(x = saga, grid = dem, nx = 20, ny = 20)

## End(Not run)
