The Amazon is the largest tropical rainforest in the world, nearly as big as the continental United States. But every year, less of that forest is still standing. Today's deforestation across the Amazon frontier is tractors and bulldozers clearing large swaths to make room for industrial-scale cattle ranching and crops. Landsat satellite data is used to map land cover in Brazil with a historical perspective, going back to 1984.Music: Organic Circuit by Richard Birkin [PRS]; Into the Atmosphere by Sam Joseph Delves [PRS]; Ethereal Journey by Noé Bailleux [SACEM]; Wildfires by Magnum Opus [ASCAP]; Letter For Tomorrow by Anthony d’Amario [SACEM].Complete transcript available.Watch this video on the NASA Goddard YouTube channel. || Amazon_clearing_poster.jpg (3840x2160) [2.4 MB] || Amazon_clearing_DSC_1491.jpg (6000x4000) [5.3 MB] || Amazon_clearing_poster_searchweb.png (320x180) [88.6 KB] || Amazon_clearing_poster_thm.png (80x40) [5.8 KB] || 13694_Amazon_deforestation_yt.mp4 (1920x1080) [417.9 MB] || 13694_Amazon_deforestation_tw.mp4 (1280x720) [89.4 MB] || 13694_Amazon_deforestation_yt.webm (1920x1080) [45.5 MB] || 13694_Amazon_deforestation-captions.en_US.srt [7.1 KB] || 13694_Amazon_deforestation-captions.en_US.vtt [6.9 KB] ||

Hurricane Maria transformed the lush rainforests of Puerto Rico leaving lots of openings in the forest canopy. NASA scientists studied the island's forests before and after the storm. Goddard's Lidar, Hyperspectral, and Thermal Imager (G-LiHT) is a portable instrument that maps forest health and structure from a small airplane resulting in detailed 3-D views of the forest. G-LiHT sends out 600,000 laser pulses every second mapping leaves and branches, rocks and streams. Almost 60% of the canopy trees lost branches, snapped in half, or were uprooted. Trees with wide, spreading crowns were reduced to a slender main trunk. Forests in Puerto Rico are now one-third shorter on average, after Hurricane Maria. The disturbances affected the whole ecosystem, from soils and streams to birds and frogs. G-LiHT data will help scientists understand how forests and wildlife respond to future changes. || SIGGRAPH_lidar_over_Puerto_Rico.01000_print.jpg (1024x576) [90.3 KB] || SIGGRAPH_lidar_over_Puerto_Rico.01000_searchweb.png (320x180) [89.6 KB] || SIGGRAPH_lidar_over_Puerto_Rico.01000_thm.png (80x40) [7.1 KB] || SIGGRAPH_PuertoRicoLidar.webm (1920x1080) [19.9 MB] || SIGGRAPH_lidar_over_Puerto_Rico.webm (1920x1080) [21.4 MB] || SIGGRAPH_PuertoRicoLidar.mp4 (1920x1080) [253.0 MB] ||

The Landsat Data Continuity Mission will continue the legacy of the 40-year Landsat program. This video examines two uses of Landsat data to monitor agriculture. Both wineries and timber companies rely on Landsat data to check whether their crops are getting enough (or too much) water and fertilizer.For complete transcript, click here. || G2012-071_Landsat_Users_Ag_MASTER_ipod_lg.01727_print.jpg (1024x576) [21.4 KB] || G2012-071_Landsat_Users_Ag_MASTER_ipod_lg_web.png (320x180) [19.5 KB] || G2012-071_Landsat_Users_Ag_MASTER_ipod_lg_thm.png (80x40) [2.4 KB] || G2012-071_Landsat_Users_Ag_MASTER_720x480.webmhd.webm (960x540) [53.6 MB] || G2012-071_Landsat_Users_Ag_MASTER_ipod_lg.m4v (640x360) [42.5 MB] || G2012-071_Landsat_Users_Ag_MASTER_ipod_sm.mp4 (320x240) [22.8 MB] || GSFC_20120927_Landsat_m11097_Users_Ag.en_US.srt [4.5 KB] || GSFC_20120927_Landsat_m11097_Users_Ag.en_US.vtt [4.3 KB] || G2012-071_Landsat_Users_Ag_MASTER_youtube_hq.mov (1280x720) [133.3 MB] || G2012-071_Landsat_Users_Ag_MASTER_appletv.m4v (960x540) [104.9 MB] || G2012-071_Landsat_Users_Ag_MASTER_1280x720.wmv (1280x720) [120.8 MB] || G2012-071_Landsat_Users_Ag_MASTER_prores.mov (1280x720) [3.5 GB] || G2012-071_Landsat_Users_Ag_MASTER.mov (640x360) [101.6 MB] || G2012-071_Landsat_Users_Ag_MASTER_720x480.wmv (720x480) [112.3 MB] || G2012-071_Landsat_Users_Ag_MASTER_youtube_hq.hwshow [65 bytes] ||

In a constantly changing world, the protection of our planet’s endangered species and ecosystems is a priority for ecologists. Recently, a group of researchers at the University of Idaho have worked to combine their extensive on-the-ground research of the endangered Yuma Ridgway’s rail with Landsat’s vast archive, to create a habitat suitability model that can be used by land managers. By using this model, it gives land managers the tools and data to make decisions of how to best carry out conservation for the Yuma Ridgway’s rail on a year to year basis. With the success of this initial model, it’s hypothesized that this tool will be able to help additional species in the area and others down the road.To view the map, click https://sites.google.com/view/habitatsuitability-yrr/homeThe Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey (USGS). Landsat satellites have been consistently gathering data about our planet since 1972. They continue to improve and expand this unparalleled record of Earth's changing landscapes for the benefit of all. ||

For helping communities across the United States stay up-to-date on their flood risk, the NASA/USGS Landsat satellites can take a bow. The Federal Emergency Management Agency uses Landsat images, which can illustrate urban changes, as a key indicator of sites where the agency should further investigate the flooding potential. With its archive of images capturing sprawling cities and new developments, Landsat can help FEMA track how building and construction is impacting an area’s landscapeEarth-observing Landsat satellites have been capturing images of the planet’s surface since 1972. Landsat 8 is the newest satellite in the program, a joint effort between NASA and the U.S. Geological Survey. It launched Feb. 11, 2013, and collects more than 400 images per day. New and archived Landsat data are available free to the public over the internet – and researchers have put the data to a multitude of uses. One is called the National Urban Change Indicator, or NUCI, created by MacDonald, Dettwiler, and Associates, LTD. It’s the results from a process that mines Landsat images over a 27-year period to identify areas of “permanent change,” where soil has been paved over for parking lots or other concrete structures.NUCI results act as a red flag for FEMA, helping the agency focus its mapping efforts and budget. But if maps identify a high risk of floods for a certain community, residents can take action, including elevating houses, building flood barricades, and more. ||

To get a detailed look at vegetation and land cover, NASA uses an airborne instrument called Goddard’s Lidar, Hyperspectral and Thermal Airborne Imager, or G-LiHT. From the belly of a small aircraft flying one thousand feet above the trees, G-LiHT collects multiple measurements of forests, including high-resolution photographs, surface temperatures and the heights and structure of the vegetation.

Landsat satellites have been gathering data for 48 years, equipping scientists and farmers to answer big questions about how to improve agriculture around the world. From tracking crop production, assessing crop health, and monitoring water use, Landsat data provides tangible benefits to the USA and the world. Landsat satellites are built and lauched by NASA, and operated by USGS.

Agriculture in Pakistan is dependent on irrigation from the Indus River, but over the years, these freshwater resources have become scarce. Today, it is one of the world’s most depleted basins. To tackle this, farmers are attempting to predict and track freshwater resources with the help of NASA satellites and cell phones. ||
