Mapfile Reference Document
Mapfiles are the basic configuration mechanism for map generation in Designer, using a file that installs to the Runtime data directory:
The different base layer maps offered through Alteryx Spatial packages all have their own authored mapfiles. These can be located in the C:\Program Files (x86)\Alteryx\DataProducts\AlteryxMap directory under the respective base layer map name folder. The mapfile is named for the layer set with a *.map file extension (i.e., UsgsNorthAmerica.map)
The Mapserver documentation describes in detail the various parameters that make up the Mapfile and how to edit this file so your map output can best fit your needs.
