This synthetic aperture radar (SAR) backscatter image from the European Space Agency's Sentinel-1C platform shows Singapore as observed on February 17, 2026. Singapore is one of the world's busiest seaports, and multitudes of container ships are scattered all along the Singapore Strait (in black) in this image. The container terminals are located in the south western section of Singapore.
The radiometric terrain corrected SAR backscatter from the Sentinel-1 (RTC-S1) product, produced by NASA's Observational Products for End-Users from Remote Sensing Analysis (OPERA) project, provides terrain-corrected radar images with a 30-meter pixel spacing. SAR delivers all-weather, day-and-night images of Earth's surface.
In this false-color scale, vegetated areas appear green; urban and/or sparsely vegetated areas appear white/pink; calm water surfaces, dry sand, and frozen ground appear black; and rough water appears purple or magenta. There are other land covers not listed that may have similar appearance, and it is recommended that users consult auxiliary datasets to help determine the land cover of interest.
The OPERA RTC-S1 product contains modified Copernicus Sentinel data corresponding to the same time period. The OPERA project, managed by NASA's Jet Propulsion Laboratory and funded by the Satellite Needs Working Group (SNWG), creates remote sensing products to address Earth observation needs across U.S. civilian federal agencies.
