The European Space Agency (ESA) has dedicated a substantial part of its programmes to observing the Earth since the launch of its first meteorological mission Meteosat in 1977. Following this mission, the subsequent series of Meteosat satellites, the ERS-1 and ERS-2 missions and, more recently, Envisat, the largest Earth observation (EO) satellite ever built, have provided a wealth of data about the Earth, its climate and changing environment.
If you’re a scientist or engineer cobbling together a geospatial project, say you’re trying to figure out how many people would be threatened by a tsunami in the Indian Ocean, a truism holds that you spend 80 percent of the time hunting down usable data. The data, when they exist at all, often are archived in incompatible formats, have varying degrees of accuracy and precision, and sometimes require a good deal of political savvy to find.
Another study concludes that the rate at which the Greenland ice mass is sliding into the ocean is increasing.
The United Kingdom’s Met Office is one of the world’s leading providers of environmental and weather-related services.

The noted British astronomer Fred Hoyle predicted shortly after the launch of Sputnik in October, 1957 that when we humans could obtain a picture of Earth from deep space, life here would never be the same. This was a time in history when the average Westerner’s concept of the universe was hardly more sophisticated than “God in the heavens, man in the middle and everything else below.” That is to say that only a very few scientists had foresight as to the extent and complexity of the cosmos that would be revealed following the arrival of the space age and its modern technologies.
NASA satellites continue to capture remarkable new images of the wildfires raging in Southern California. At least 14 massive fires are reported to have scorched about 425 square miles from north of Los Angeles to southeast of San Diego.
This brief article describes the how satellite imagery can deliver the not-so-good news.
Cindy Lee Van Dover is a pioneer: a submarine pilot and the first woman to direct the Duke University Marine Laboratory. This interview gives insite into the life, career and discoveries of an impressive woman.
The Google Librarian Central site has up a piece by Mark Aubin, a Software Engineer who works on Google Earth. Aubin explains some of the process behind capturing satellite imagery for use with the product. ‘Most people are surprised to learn that we have more than one source for our imagery. We collect it via airplane and satellite, but also … Read More
The BBC is reporting that a Californian company has created software that can layer relevant recorded sounds over locations in Google Earth. The firm, Wild Sanctuary, has thousands of hours of recordings from all over the world. Company director Dr. Krause has spent over 40 years collecting sounds from natural and man-made habitats. ‘… his recordings include more than 15,000 … Read More
