This GeoEye-1 satellite image of Kennedy Space Center image was taken before the launch of Space Shuttle Discovery which is one of the retired satellite orbiters of the Space Shuttle program of NASA, the space agency of the United States,and was operational from its maiden flight, STS-41-D on August 30, 1984, until its final landing… Continue reading Image of the Day : Kennedy Space Center
A new term doing rounds of Remote Sensing circles is Enhanced Line Rate imagery. What actually is Enhanced Line Rate? Pushbroom sensors such as IKONOS acquire data using a line of sensors arranged perpendicular to the flight direction of the spacecraft. It is a large focal plane detector array, capable of generating thousands of line… Continue reading Enhanced Line Rate imagery
SPOT-6 was launched on September 9, 2012. The technical commissioning of the satellite was successfully completed on December 14, 2012. Since then SPOT 6 has been continuously acquiring remote sensing data. The processed imagery output from this sensor is 1.5m with 4 spectral bands. Due to its wide swath width of 60km it has been… Continue reading 2013 Additions to Satellite Archives – 1 : India
DigitalGlobe’s(previously GeoEye’s) satellites GeoEye-1 and Ikonos are two stalwarts of International Remote Sensing arena. Ikonos satellite was the first one to acquire imagery at sub-meter resolution. This made satellite imagery more attractive general public. People were really able to identify cultural features or even their houses in the satellite image. This was not possible until… Continue reading 2013 Additions to Satellite Archives – 2 : India
As we discussed in another post, recent meteorite impact on the Russian town of Chebarkul where a fragment of the meteorite that fell to Earth on 15 February left a hole in the middle of the frozen lake to the west of the town. The meteor was darting at speed close to 18km per second.… Continue reading Russian Meteorite Impact Site : Pléiades Satellite imagery
The Dead Sea, despite its name, is not actually a sea but a lake located between Israel, the West Bank, and Jordan. It is world-famous for its extreme salinity (33.7%) and for being the lowest land elevation on Earth at -423 meters below mean sea level (MSL). For centuries, the Dead Sea has attracted visitors… Continue reading Image of the Day : Lowest Place on Earth
Designed by the French engineer Michel Virlogeux and British architect Norman Foster, Millau Viaduct is the tallest bridge in the world with one mast’s summit at 343.0 metre above the ground. It is the 12th highest bridge deck in the world, being 270 metres between the road deck and the ground below. It is basically… Continue reading Image of the Day : Millau Viaduct
Landsat Data Continuity Mission(LDCM) or soon to be rechristened Landsat 8 is operating normally as per the latest update from NASA. The two Systems onbaord Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) have been ramping up their collection rate steadily and have now reached 4000 scene/day. Optimal design rate for the both sensors… Continue reading Landsat 8 Going Full Steam, Collecting 400 scenes a Day !
The Landsat Data Continuity Mission (LDCM), also known as Landsat 8, was one of the most anticipated satellite launches in recent history. Its arrival was particularly crucial following the failure of the Scan Line Corrector (SLC) onboard the Landsat 7 ETM+ sensor in 2003—just four years after its launch. The malfunction caused nearly 22% data… Continue reading Landsat 8 and Landsat 7 comparison, First Look
On the first day of February we did a post on merger of DigitalGlobe and GeoEye. You can see it here. Market capitalization of the merged entity is $2.1 billion. The new entity, still named DigitalGlobe, is in the course of merging processes, products and pricing. In order to systematically tackle the complexity of merger… Continue reading Post Merger DigitalGlobe announces ‘Bridge’ Pricing
