 TRFIC
Products & Services:
New and easier
way to download derived products:The Legal
Amazon 3x6 degree grids and the Legal
Amazon WRS tiles can now be downloaded much faster using ARC/INFO
format. The TRFIC archive tops 6,000 scenes: The TRFIC archive is now the largest Landsat archive outside the federal government, with user access at low costs. Deforestation and Regrowth grid data in the Legal Amazon: You can now download 16km x 16km and/or 1km x 1km gridded data of deforestation for the years 1975, 1978, 1986, and 1992. Follow this link to download data. TRFIC
Technology:
Web-GIS services are now on-line: A new prototype data search and display engine is now available. This tool, the TRFIC Core System, is the result of close R & D collaboration between TRFIC and ESRI, the industry leader in GIS technology. Follow this link to try it. The TRFIC GeoZoom™ browser is now also available in our HTML interface: This image browser allows users to view scenes at multiple resolutions on-the-fly, including full resolution, to zoom into to their specific site. It also provides custom selection of band combinations. Follow this link to try it. TRFIC
Science & Applications:
New Science results using Landsat data to compute Amazon carbon fluxes: A recent paper in the January issue Nature, uses a model and Landsat derived deforestation to estimate lower net fluxes of carbon than pervious calculations. View or download the paper in PDF format here. TRFIC selected to support the International Global Observations of Forest Cover program: The GOFC program is a collaboration of space agencies around the world to build an operational forest monitoring system. For more information follow this link. The TRFIC Technology
adapted for use by the Upper Great Lakes RESAC (Regional Earth Science
Applications Center): The
same technology developed for tropical forest data access and analysis
has been redeployed for local and regional applications in Michigan and
the Great Lakes Region. Follow this

General Information Rain
Forest Information:
Rain Forest Report Card: Rain forests occur throughout the world where there are heavy rains and growing forests. By definition, a rain forest needs to receive more than 2500 mm (8 feet) of rain annually. The Rain Forest Report Card is focused on tropical rain forests occurring between the Tropics of Cancer and Capricorn, 23.5 degrees North and 23.5 degrees South respectively. Landsat
Information:
Introduction to Landsat: The LANDSAT Program is the longest running exercise in the collection of multispectral, digital data of the earth's surface from space. The program has operated continuously since LANDSAT 1 (then the Earth Resources Technology Satellite (ERTS) 1) was launched on July 23, 1972. Landsat 7 Handbook: There are 12 chapters ranging from the description of the Landsat 7 program, the Landsat 7 Spacecraft, to the Data Products... Landsat Thematic Mapper (TM) Data Documentation: Landsat Thematic Mapper (TM) data provide land surface information from the early 1980's to the present... Landsat Multispectral Scanner (MSS) Documentation: An MSS scene has an Instantaneous Field Of View (IFOV) of 68 meters in the cross-track direction by 83 meters in the along-track direction (223.0 by 272.3 feet respectively)... Landsat Ground Stations Document: A list of the Landsat Ground Station Operations Working Group.
