mimap2isis

This program converts PDS formatted Kaguya MI MAP files to ISIS cube format.

The PDS formatted MI MAP file is a 9-band mosaic of derived data products. The Kaguya (SELENE) mission's Lunar Imager/Spectrometer (LISM) Multi-band Imager (MI) instrument acquired 5 bands of visible and 4 bands of near-infrared images. The MI images in the mosaic have been radiometrically calibrated, tone matched, projected to a simple cylindrical projection, and mosaicked.

Input:

The FROM parameter is used to specify a standard PDS file or a detached label file. Both the detached label and the associated image file must exist in the same working directory. The IMAGE parameter does not need to be defined, unless the program cannot find the image file specified in the label file upon the program's execution.

• Standard PDS formatted file (attached label)
• Detached label file
• Image file without labels

Output:

An ISIS formatted multi-band cube with corrected labels is output to the filename specified.

Default Settings: The default settings normally result in successful ingestion of Kaguya MI MAP products. Occasionally, the user must modify default values to obtain an image that meets specific requirements. The program will apply a correction by changing the sign of the SAMPLE_PROJECTION_OFFSET keyword value. The modified label is written to a temporary detached label file and then used to import the Kaguya MI MAP file into ISIS.

Special Pixel Assignment: The incoming special pixel values are assigned equivalent values for special pixels in ISIS. If any incoming pixel value falls within two different special pixel types, the special pixel with the higher priority is assigned. The precedence for special pixels in ISIS from highest to lowest is 1)NULL, 2)HRS, 3)LRS, 4)HIS, and 5)LIS.

The user may also specify a range of input pixel values to be assigned to specific ISIS special pixels. If the range of pixel values defined by the user for the different special pixels overlap, the special pixel with the highest priority is assigned. For example, if NULLMIN=0.0, NULLMAX=3.0, LISMIN=3.0, and LISMAX=5.0, the actual raw value 3.0 could be designated as NULL or LIS; however, the actual assignment is NULL (highest priority).

Processing Notes: If the output MI MAP cubes are to be mosaicked using programs such as automos, then please be aware that you must set the matchbandbin option to false when mosaicking. This is required because the BaseBand keyword in each file will not always match and this will cause your mosaic to fail if you don't set the matchbandbin option to false.
