By default, ISIS limits the size of the output files it will create to 12 GB. When projecting high-resolution data such as LROC, into polar stereographic, the resulting cubes have a lot of NoData pixels that inflate the size of the file. It is very common for full-resolution LROC images in polar stereographic projection to have sizes > 12GB.
You have several options for dealing with this:
- Do what the error message suggests and edit
~/.Isis/IsisPreferences to increase the MaximumSize threshold to a larger value
- Stretch your input images and convert them to 1-Byte per pixel rather than 4 Bytes per pixel (will shrink file size by factor of 4). Based on your screenshots, this would be enough for some, but not all of your images. See Example 2 in the cubeatt documentation for a simple example of how to do this.
- Specify a larger value for PixelResolution in your map template. (If you really need 0.5 meters/pixel, this won’t be an option)
If you edit your IsisPreferences file, look for a section beginning with “Group = CubeCustomization.” A few lines below that you will see “MaximumSize = 12”. Just change the 12 to a larger value (for LROC, perhaps try 125; that’s the value I use and it works much of the time).
There are also ways to split the output into several smaller images, but that’s a little more complicated to set up.
