|-
|"-gpkg"||Output to GeoPackage format
|-
|"-nc"||Output to NetCDF format. Note: the old -nc command has been deprecated in the 2023-03-AA release. For backward compatibility the following command can be used instead <tt>"-conv -nc"</tt>
|-
|"-co"||Creation option switch. See <b><u>[[#Creation_Options | Creation Options]]</u></b> section below.

===Changes to Old Switches===
* -nc - The <tt>"-nc"</tt> switch previously converted the input file to a NetCDF raster. The -nc switch now specifies that the output format should be NetCDF (for all operations). Use the following command to get the previous behaviour <tt>"-conv -nc"</tt>.
* -conv - The <tt>"-conv"</tt> switch now requires an output format to be specified (e.g. to convert from FLT to ASC use <tt>-conv -asc</tt>). Previously it would convert only between ASC and FLT and the output format was determined by the input format.
Another change in behaviour in the 2023 release is that the output format can also be specified by adding a supported extension when using the <tt>"-out [output_name.ext]"</tt> switch.
