The Integrated Software for Imagers and Spectrometers Technical Committee (TC) is the technical governing body of the ISIS Software Package. Its role is to set policy for the ISIS project as described in the TC Charter.
ISIS is defined as the contents of the repository located at https://github.com/USGS-Astrogeology/ISIS3. This is the location of the ISIS low-level API and applications.
At any one time the ASC Software projects have a number of strategic initiatives underway. The goal of the TC is to have a champion for each of these initiatives and to support the initiatives in order to enable their success.
