True-color image of Singapore. This image was acquired on 10 May 2021 by the Multi-Spectral Instrument (MSI), aboard the European Space Agency's Sentinel-2A and 2B satellites. Singapore is a city-state located in Southeast Asia. The main island is separated from Malaysia to the north by Johor Strait. Singapore is the largest port in Southeast Asia and one of the world's busiest. Multitudes of container ships are evident in the Singapore Strait to the south of the main island.
The imagery available in NASA's Worldview is part of the Harmonized Landsat Sentinel-2 (HLS) project which provides 30 meter resolution true-color surface reflectance imagery from the Operational Land Imager (OLI) instrument aboard the NASA/USGS Landsat 8 satellite, and the Multi-Spectral Instrument (MSI) aboard the European Space Agency Sentinel-2 A and B satellites. The data from the two instruments aboard the three satellites are processed through a set of algorithms to make the imagery consistent and comparable across the instruments. This includes atmospheric correction, cloud and cloud-shadow masking, spatial co-registration and common gridding, illumination and view angle normalization, and spectral bandpass adjustment.
