= How to convert Gaskell ICQ model to other formats =

== Convert to PLT ==
 * Use AltWg tool ICQ2PLT

== Convert to OBJ ==
 * Use AltWg tool PLT2OBJ

== Convert to GeoTIFF ==
 * Use spheremapsB to convert to a pgm, then GDAL to convert pgm to GeoTIFF. GDAL can also be used to make the GeoTIFF readable by ISIS. Further details can be found in [[Convert MAP]] since it is very similar. spheremapsB will work with user specified maps; these maps can be maplets or bigmaps.

== Convert to DSK ==
 * This is the format used by NAIF. Use the program mkdsk, which is part of the NAIF SPICE TOOLKIT. Here is how to setup the required files.
{{{
mkdsk -setup setup.txt
}}}

Here's an example of setup.txt for Tethys. Will need a the leap second kernel naif00112.tls. Here's a link to the NAIF description of how to use mkdsk. [[https://naif.jpl.nasa.gov/pub/naif/utilities/MacIntel_OSX_32bit/mkdsk.ug|Naif MKDSK link]]. Note that the ICQ must have the first line as the Q size, as laid out in the NAIF link.

== Important Parameters ==
 * DATA_TYPE, as of 05 Apr 2017 version, is always set to 2
 * PLATE_TYPE should be set to 2 for a Gaskell model.
