The border between Belize and Guatemala illustrates striking differences in land use practices. In a study of deforestation published in 2016, Chicas and co-authors found that in their study area between 1991 and 2014, on the Guatemalan side of the border forested land declined 32%; in Belize, forested area declined 11%. In part of their study area shown in this image, the difference is more dramatic: near-pristine forest in Belize on the right, and agricultural fields in Guatemala on the left. The image was acquired May 10, 2016, covers an area of 27 by 41 km, and is located at 16.7 degrees north, 89.2 degrees west.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
