Radarsat Antarctic Mapping Project

Project Description
The Radarsat Antarctic Mapping Project (RAMP)is a joint effort of NASA
and the Canadian Space Agency (CSA). The project was conducted
collaboratively by the Byrd Polar Research Center, Vexcel Corporation,
the Alaska SAR Facility, and the Jet Propulsion Laboratory, with
funding from NASA's Pathfinder Program. The project also received
valuable assistance from the National Science Foundation, the
Environmental Research Institute of Michigan, and the National Imagery
and Mapping Agency.

In 1997, the Canadian RADARSAT-1 satellite was rotated in orbit, so
that its synthetic aperture radar (SAR) antenna looked south towards
Antarctica. This permitted the first high-resolution mapping of the
entire continent of Antarctica. In less than three weeks, the
satellite acquired a complete coverage of radar image swaths as part
of the first Antarctic Mapping Mission (AMM-1). Swath images have been
assembled into an image mosaic depicting the entire continent at 25 m
resolution. The mosaic provides a detailed look at ice sheet
morphology, rock outcrops, research infrastructure, the coastline, and
other features of Antarctica, as well as representing calibrated radar
backscatter data which may provide insight into climate processes
affecting the upper few meters of snow cover.
