EARTH AS ART - IMAGENS ARTÍSTICAS DA TERRA

I did this post in March 07, 2006 but I think it's worth to have a second look on Ecological Day. This time I will post here the name and the links of the participants on Ecological Day in order to provide the visitation between all them. So please, I ask you to warn me of your participation in the comments or by e-mail.

Fiz este post em 7 de Março de 2006 e achei que valia a pena publicá-lo novamente no Ecological Day. Desta vez vou postar aqui o nome e o link dos participantes do Ecological Day, para poder propiciar a visitação entre eles. Assim, peço o favor de me avisarem de sua participação nos comentários ou por email.

Earth As Art, A Landsat Perspective

A series of Landsat satellites have imaged the Earth's surface for nearly thirty years, providing data for applications in business, science, education, government, and national security. The Landsat satellite currently in orbit is Landsat 7. These images are actual pictures of the Earth, created by printing visible and infrared data in colors visible to the human eye. Band combinations and colors were chosen to optimize their dramatic appearance. Many of the satellite images we see have very different colors than the ones we are used to seeing with our own eyes. To understand why do satellite images look so different, read this interesting article: Landsat 7 Compositor.

Uma série de satélites Landsat têm produzido imagens da superfície da Terra há quase trinta anos, fornecendo dados para utilização em negócios, ciência, educação, governo e segurança nacional. O satélite Landsat actualmente em órbita é o satélite Landsat 7. Essas imagens são imagens reais da Terra, criadas por impressão em dados visíveis e infravermelho, cores visíveis ao olho humano. As bandas e as combinações de cores foram escolhidas para otimizar o seu aspecto dramático. Para entender o que são imagens de satélite e como elas se diferenciam de fotografias, você pode ler este interessante artigo, Landsat 7 Compositor.



Lena Delta Asia, in Russia: The Lena River, some 2,800 miles (4,500 km) long, is one of the largest rivers in the world. The Lena Delta Reserve is the most extensive protected wilderness area in Russia.


Parana River Delta, in northwest of Buenos Aires: The Parana River Delta is a huge forested marshland about 20 miles (32 km) northwest of Buenos Aires, Argentina. The area is a very popular tour destination.

Araca River, in Brazil: Brazil's Araca River is a tributary of the Negro River, which feeds into the Amazon.

Guinea-Bissau, West Africa: The Guinea-Bissau is a small country in West Africa.

Namib Desert, Namíbia, Africa: Namib-Naukluft National Park is an ecological preserve in Namibia's vast Namib Desert. Coastal winds create the tallest sand dunes in the world here, with some dunes reaching 980 feet (300 meters) in height.

Malaspina Glacier, Alaska: The tongue of the Malaspina Glacier, the largest glacier in Alaska, fills most of this image. The Malaspina lies west of Yakutat Bay and covers 1,500 sq mi (3,880 sq km).

Ganges River Delta, Bay of Bengal: The Ganges River forms an extensive delta where it empties into the Bay of Bengal. The delta is largely covered with a swamp forest known as the Sunderbans, which is home to the Royal Bengal Tiger.

Volga River Delta, Eurasia: Where the Volga River flows into the Caspian Sea, it creates an extensive delta. The Volga Delta is comprised of more than 500 channels and sustains the most productive fishing grounds in Eurasia.

West Fjords, Iceland: The West Fjords are a series of peninsulas in northwestern Iceland. They represent less than one-eighth the country's land area, but their jagged perimeter accounts for more than half of Iceland's total coastline.

Participants on Ecological Day: Animal Artificial, Leituras & Imagens, Saia Justa, Paz's New York Minute, Varal de Idéias, Flor de Lis, Pietro Brosio Gallery, Côté cour, Côté jardin, A Casa do Mago, Luz de Luma, yes party!, Entremeios,
