This true-color corrected reflectance image of Angkor Wat, Angkor Thom, West Baray, and the surrounding area in Cambodia was captured on April 12, 2025, by the Multispectral Imager (MSI) aboard the ESA (European Space Agency) Sentinel-2C satellite.
Angkor is a UNESCO World Heritage Site and is one of the most important archaeological sites in Southeast Asia. The area contains different capitals of the Khmer Empire dating from the 9th to the 15th century. It covers over 400 square kilometers and includes many temples as well as hydrological engineering systems like reservoirs, dykes, and canals. Visible in the satellite image are the square-shaped outlines of Angkor Thom, also known as Nokor Thom, in the center of the image, and Angkor Wat just below it. Both walled temple cities are surrounded by moats. To the west of Angkor Thom is the West Baray, the large rectangular reservoir oriented east-west, approximately 7.8 by 2.1 kilometers.
The image is from the Harmonized Landsat and Sentinel-2 (HLS) project. HLS provides 30-meter resolution, true-color surface reflectance imagery from the OLI and OLI-2 instruments aboard Landsat 8 and 9 and from MSI aboard the ESA Sentinel-2 satellites. Data from the four instruments are processed through a set of algorithms to make the imagery consistent and comparable. This processing includes atmospheric correction, cloud and cloud-shadow masking, spatial co-registration and common gridding, illumination and view angle normalization, and spectral bandpass adjustment.
