Campaign for Dark Skies
British Astronomical Association
Astronomers call the wasted light that goes up into the sky "Light Pollution". They would like to see BETTER lights which shine downwards where the light is needed and not upwards where it isn't. The energy implications of Light Pollution are among the topics addressed on this site. Includes satellite map of UK at midnight

Digital Tectonic Activity Map
National Aeronautics and Space Administration (USA)
The Digital Tectonic Activity Map (DTAM) is a new visualization tool for both researcher and educator alike to better understand tectonic activity of our planet for the past 1 million years. DTAM is a Geographical Information System (GIS) that displays a realistic synoptic view of present global tectonism by filling in the cartographic gap between conventional geological maps and plate reconstruction maps. The DTAM was created using current global datasets of seismicity, volcanism, and plate motions that were integrated with topography and bathymetry measurements derived from satellite gravity data. Macroscopic structural features were integrated via field studies from various researchers, space geodesy, and space-borne imagery (e.g. astronaut photography, Landsat). This integrative technique provides a new and unique visualization tool that presents an actual representational view of global tectonics rather than the traditional schematic illustrations (i.e. plate maps) of the past. In English.

Earth Observatory
National Aeronautics and Space Administration (NASA), The U.S.
Earth Observatory provides a freely-accessible publication on the Internet where the public can obtain new satellite imagery and scientific information about our home planet. The focus is on Earth's climate and environmental change. Materials published on the Earth Observatory are freely available for re-publication or re-use, except where copyright is indicated. The site includes images and data on Biosphere, Chlorophyll, Cloud Fraction, 1km (sq.) Fires, 4km (sq.) Fires, Land Cover Classification, Outgoing Heat Radiation, Vegetation, Ozone, Rainfall, Sea Surface Temperature, Incoming Solar Radiation, and Surface Temperature. An 'Experiments' section allows students to operate in a virtual Laboratory, where they can learn how and why the Earth changes through the use of interactive computer models and the art and science of space-based remote sensing. Experiments include oil spill, earthquake, and hurricane activities, and the effects of siting an oil refinery in a coastal harbor.

Earth Observing System, Direct Broadcast
National Aeronautics and Space Administration (USA)
The Direct Access System for the Earth Observing System (EOS) spacecraft provides a means of transmitting some, or all, of the EOS science data directly via X-band to ground. The Direct Access System, or some portions thereof, will fly on the EOS-AM, EOS-PM, and some subsequent Office of Earth Science spacecraft. Included in this Direct Access System is a Direct Broadcast Service which will transmit real-time data from the satellite to anyone within line-of-sight during most of the orbit. The web site includes Overpass Predictor, Real Time Images, Test Images, and Documents. In English.

Earthwatch
United Nations System-Wide Earthwatch
United Nations Environment Programme
The mission of Earthwatch is to coordinate, harmonize and integrate observing, assessment and reporting activities across the UN system in order to provide environmental and appropriate socio-economic information for national and international decision-making on sustainable development and for early warning of emerging problems requiring international action. Includes links to sources of near-real-time information on the state of the planetary environment, including Atmospheric Aerosols, Fires, Oceans, and Coral Reefs. In English.

EROS
The Earth Resources Observation Systems (EROS) Data Center (EDC)
U.S. Department of the Interior / U.S. Geological Survey
A data management, systems development, and research field center for the U.S. Geological Survey's (USGS) National Mapping Division. Since 1991, the EDC has supported the United Nations Environment Programme/Global Resources Information Database, making environmental data available to developing countries. The EDC is designated as a World Data Center for Remotely Sensed Land Data and is a cooperator in many domestic and international programs. The EDC houses a variety of USGS digital cartographic data products collectively referred to as US GeoData. The EDC's archives also hold the world's largest collection of civilian remotely sensed data covering the Earth's land masses, housing millions of satellite images and aerial photographs. As part of its role as a data archive, the EDC operates the National Satellite Land Remote Sensing Data Archive, a legislatively mandated program designed to maintain a high quality data base of space-acquired images of the Earth for use in studying global change and other related issues. Data searching and ordering may be performed through a variety of information management systems and interfaces, including: Some distribution restrictions may apply. Questions regarding data availability are directed to Customer Services.

NASA Regional Planetary Image Facility
National Aeronautics and Space Admistration (USA)
The NASA Regional Planetary Image Facility, an international system of planetary image libraries, was established in 1977. These facilities maintain photographic and digital data as well as mission documentation and cartographic data. Each facility's general holding contains images and maps of planets and their satellites taken by solar system exploration spacecraft. In English.
