The Indian Space Research Organisation(ISRO) plans to build, Cartosat-3, capable of taking images of the earth with a resolution of 0.25 metres. Currently, GeoEye-1 provides the highest resolution satellites imagery taken by a commercial satellite. Currently owned by DigitalGlobe after recent merger with GeoEye, this American satellite provides images at 0.41m resolution. WorldView-2, another satellite… Continue reading ISRO to Launch Cartosat 3 with 25 cm resolution
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
This half-meter resolution satellite image shows the Atlantis Paradise Island resort and waterpark on Paradise Island in the Bahamas, located southeast of the United States in the Atlantic Ocean.

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
Dead Sea is a actually a lake sandwiched between Israel, West bank and Jordan. It is known worldwide for one of the most saline(33.7% salinity) and lowest land elevation(-423 MSL) on its shores. It is a popular tourist destination due to religious, scientific, and recreational factors. The Dead Sea has attracted visitors from around the… 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 !
Landsat Data Continuity Mission or Landsat 8 has been long awaited since the failure of the Scan Line Corrector onboard the Landsat ETM+ satellite sensor, just 4 years after its launch in 1999. There was 22% data loss in each scene which severely affected efforts on Climate change and various other Environmental studies. NASA was… 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
