JERS-1 Synthetic Aperture Radar Data held at the Alaska Satellite FacilityEntry ID: ASF00002
Abstract: The data set consists of all JERS-1 SAR data acquired by the Alaska Satellite Facility (ASF) operated by the Geophysical Institute of the University of Alaska in Fairbanks. The data set is global in extent with strengths in images of rain forested regions and the North American Boreal Forest.
Available products include:
... Full-res images are 4-look SAR images with 30 m resolution and 12.5 m
pixel spacing over a 100 km x 100 km area. These are 8192 pixel x
8192 pixel x 8 bit (64MB) images. The data is corrected to the
GEM06 geoid model.
Lo-res images are produced by 8 x 8 averaging the full-res data. The
resulting image is 1024 pixels x 1024 pixels x 8 bits (1 MB).
Complex images, are 1-look data with approximately 10 m resolution covering an area of 30km x 50 km. Data is formatted as 12,888 pixel x 2048 pixel x 32 bit complex integers (16I, 16Q- about 100MB). The data contains backscatter amplitude and phase useful for interferometry studies of topography and feature motion.
Approval by NASA is required to obtain the data. Please contact ASF User Support to become a NASA approved investigator.
