The user provides the map calculation expression. The output map name is automatically extracted from that expression by extracting the string before the '='. If the expression is more complex, the user can also provide the the output map name with the parameter output
Tiles can be defined with the width, height and overlap parameters. If processes is higher than one, these tiles will be processed in parallel.
The mapset_prefix parameter ensures that the temporary mapsets created during the tiled processing have unique names. This is useful if the user runs r.mapcalc.tiled several times in parallel (e.g. in an HPC environment).
g.region raster=ortho_2001_t792_1m r.mapcalc.tiled expression="bright_pixels = if(ortho_2001_t792_1m > 200, 1, 0)" \ width=1000 height=1000 processes=4
