Adding SPICE

Setting up ISIS

Installing ISIS: ISIS is distributed via conda and compatible with Mac and Unix
Setting up the ISIS Data Area: Download the entire ISIS data area or mission-specific data
Using Web SPICE in ISIS and ALE: Use web-enabled SPICE data via SpiceQL instead of using local data

Adding SPICE¶

An important capability of ISIS is the ability to geometrically and photometrically characterize pixels in raw planetary instrument images. Information such as latitude, longitude, phase angle, incidence angle, emission angle, local solar time, sun azimuth, and a many other pixel characteristics can be computed.

To compute this information, the SPICE ( S pacecraft and P lanetary ephemeredes, I nstrument C -matrix and E vent kernel) kernels must first be determined for the particular raw instrument image. These kernels maintain the spacecraft position and orientation over time, as well as the target position and instrument specific operating modes.

To add SPICE information to your cube, run spiceinit application on the image so that camera/instrument specific applications (e.g., cam2map , campt , qview ) will have the information they need to work properly. Generally, you can simply run spiceinit with your input filename and no other parameters:

  spiceinit FROM=my.cub

See the following ISIS documentation for information about the applications you will need to use to perform this procedure:
