    Surface velocity mosaic of the east Antarctic Ice Streams. The speed is encoded as hue and SAR is encoded as intensity in the HSV color model. The upstream velocity of the Recovery Glacier is about 100 meters/year (light blue areas). Near the grounding line, there is a local peak velocity of about 900 meters/year (yellow and red areas). ©Zhiyuan ZhaoA cutaway image of Antarctica showing the continent under its ice. ©National Geographic 2002

    Mission One Plans

    The SPA file is modified to allow for right looking acquisitions.

    AMM_final are export files detailing the prenominal and nominal missions. These can be imported into ARC.

    Interferometric SAR (InSAR) and nom_c1 include export files and html files. The latter can be read into the SPA. The number 8 suffix indicates the time automatically added by CSA to the start and end of an acquisition request.

    Ice velocity vectors obtained over the Lambert Glacier using RADARSAT SAR imagery. The areas of no motion (yellow) are either exposed land or stationary ice. The smaller confluent glaciers have generally low velocities (green, 100-300 meters per year).

    Mission 2 plans

    • Final Report: Modified Antarctic Mapping Mission (MAMM) Acquisition Plan: a detailed description of the development of the acquisition sequence for the RADARSAT spacecraft used to conduct the MAMM mission.
    • The RadarSAT-MAMM Automated Mission Planner: documentation of the results of the automated mission planner effort that were presented at a conference on artificial intelligence in Seattle, Washington.
    • Final MAMM Plans: A directory containing the user request files i.e., the RADARSAT-1 program name for the files containing the requested data acquisitions for all three MAMM cycles.
    • MAMM SPA: A directory containing an automated mission planning tool developed at JPL and used to help analyze candidate acquisition plans for compliance with various mission constraints.​
    • MAMM SPA export: Two export files; one for ascending coverage and the other for descending coverage.
