block_size

internal

Extends the 'mlr3' ML framework with methods for spatial
objects. Data storage and prediction are supported for packages
'terra', 'raster' and 'stars'.

Raster to be split into chunks.</dd>
<dt>chunksize</dt>
<dd>(<code>integer(1)</code>) 
The chunksize determines in how many subparts the prediction task will be
split into. The value can be roughly thought of as megabyte of a raster file
on disk. For example, if a prediction on a 1 GB file would be carried out
with <code>chunksize = 100L</code>, the prediction would happen in 10 chunks.
The default of <code>chunksize = 1000L</code> might be a good compromise between speed
and memory usage. If you find yourself running out of memory, reduce this
value.</dd></dl>
