LandSat : First of Three Million images - Image of the Day

LandSat : First of Three Million images - Image of the Day | Remote Sensing News | Scoop.it

Forty years ago, after more than a decade working to leave our planet, NASA launched an unprecedented mission to look back at home. Four decades later, the Landsat program is still going strong, with more than three million images of Earth in its archives and a new mission slated for launch in 2013.
On July 23, 1972, the Earth Resources Technology Satellite (later renamed Landsat 1) lifted off on a Thor-Delta (Delta 900) rocket from Vandenberg Air Force Base in California. The first images from the satellite’s Multispectral Scanner System (MSS) were received a day later by scientists gathered at NASA’s Goddard Space Flight Center in Maryland. The very first image in the Landsat archive is the MSS image above, showing the greater Dallas area of Texas on July 25, 1972. The resolution is 60 meters per pixel in this false-color image, where shades of red indicate vegetated land and grays and whites are urban or rocky surfaces.
Scientists involved in the mission weren't sure what to expect of the MSS, which used new fiber-optic technology, took pictures in four different bands of the spectrum, and scanned the Earth in strips. (More conventional television-style cameras—known as return beam vidicons (RBV)—had been expected to be the main workhorse of the satellite.) A group of scientists and technicians gathered at NASA Goddard with great anticipation, as the first MSS transmission was translated onto film by an electron beam recorder and then put into a viewing device.
As the imagery scrolled into view, there were clouds...and then more clouds...and then land. But something looked strange. A technician in the room lamented: “lt’s terrible. It has moiré patterns.” But after figuring out the location of the image—the Ouachita Mountain region in southeastern Oklahoma—scientists realized that the imagery was showing circular outcrops of the ancient fold mountains.
Any lingering anxiety in the room quickly turned to excitement, and skeptics were promptly converted into supporters. The well-known U.S. Geological Survey cartographer Alden Colvocoresses, who had been cynical about any cartographically accurate data being collected with “a little mirror in space,” turned to his colleagues after seeing the MSS imagery and said:“gentlemen, that’s a map.”....

Forest Cover Database Updates Using Multi-Seasonal RapidEye Data—Storm Event Assessment in the Bavarian Forest National Park

Forest Cover Database Updates Using Multi-Seasonal  RapidEye Data—Storm Event Assessment in the Bavarian Forest National Park | Remote Sensing News | Scoop.it
This study is a part of a research program that investigates the potential of RapidEye (RE) satellite data for timely updates of forest cover databases to reflect both regular management activities and sudden changes due to bark beetle and storms. Applied here in the Bavarian Forest National Park (BFNP) in southeastern Germany, this approach detected even small changes between two data takes, thus, facilitating documentation of regular management activities. In the case of a sudden event, forest cover databases also serve as a baseline for damage assessment. A storm event, which occurred on 13 July, 2011, provided the opportunity to assess the effectiveness of multi-seasonal RE data for rapid damage assessment. Images of sufficient quality (<20% cloud cover) acquired one day before the storm event were used as a baseline. Persistent cloud cover meant that the first “after event” image of sufficient quality was acquired six weeks later, on 22 August, 2011. Aerial images (AI) for the official damage assessment done by the BFNP administration were acquired on that same day. The RE analysis for damage assessment was completed two weeks after the post-event data take with an overall accuracy of 96% and a kappa coefficient of 0.86. In contrast, the official aerial image survey from the BFNP was first released in late November, eleven weeks later. Comparison of the results from the two analyses showed a difference in the detected amount of forest cover loss of only 3%. The estimated cost of the RE approach was four times less than that of the standard digital AI procedure employed by the BFNP.
