<li> Runs a difference operation on GPKG outputs. The layer name needed is assumed to be the same as the database name.<br>

<li> Runs a difference operation on GeoPackage outputs where the layer name is different than the database name.<br>

<li> Converts an ASC grid to a GeoTIFF with an LZW compression and horizontal predictor.<br>

<li> Runs a maximum operation on all FLT grids in a given location and outputs to a GeoPackage raster.<br>

<li> Converts GeoTIFF to a Cloud Optimised GeoTIFF. Requires <tt>-out</tt> flag since the extension for COG is also '.tif' and therefore the default output file would be the same as the input file.<br>
