Sensing the Fraser River by SAR

This image of the upper Fraser River was acquired by NASA’s SIR-C Synthetic Aperture Radar (SAR) aboard the Space Shuttle Endeavour. The ASF DAAC is currently processing the data collected during this mission to a digital format. Data will be available to download beginning in mid-2019.

Explore SAR Data at NASA's ASF DAAC.

The Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC) is home for SAR data acquired from 1978 to present from missions conducted by NASA and other countries. Most datasets are unrestricted and available to download after registering with the NASA EOSDIS Earthdata Login system.


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.
