The RADARSAT 1 Antarctic Mapping Project (RAMP) isa collaboration between NASA and the Canadian Space Agency to map Antarcticausing synthetic aperture radar (SAR). RAMP comprises two distinct mappingmissions. The first Antarctic Mapping Mission was successfully completed inOctober 1997. Data from the acquisition phase of the 1997 campaign have beenused to achieve the primary goal of producing the first high-resolution SARimage map of the entire Antarctic continent. The Modified Antarctic MappingMission (MAMM) occurred during the fall of 2000. The acquisition strategyconcentrated on collecting highest-resolution RADARSAT 1 data of Antarctica'sfast glaciers for change detection, feature tracking estimates of surfacevelocity, and interferometric analysis of velocity and coherence over theentire viewable region, which extends north of 80.1¿S latitude. This paperreviews the MAMM project and describes the techniques to be used in processingthe data. An example of data acquired over the Drygalski ice tongue, Antarcticaillustrates how MAMM data will further benefit investigations of the icy continent.
