DigitalGlobe successfully launched their WorldView-1 high resolution earth observation satellite. From the press release: "DigitalGlobe, provider of the world’s highest-resolution commercial satellite imagery and geospatial information products, today announced the successful launch and deployment of WorldView-1, the most agile commercial satellite ever flown. [...] WorldView-1, built by Ball Aerospace and Technologies Corporation with the imaging sensor provided by ITT Corporation, is a high-capacity, panchromatic imaging system featuring half-meter resolution imagery. With an average revisit time of 1.7 days, WorldView-1 is capable of collecting up to 750,000 square kilometers (290,000 square miles) per day of half-meter imagery." Directions Mag have some screenshots, while the Spatial Law blog underlines: "Some questions arose in connection with the launch regarding what restrictions the US government puts on the operations of commercial imaging satellites and under what authority."

DigitalGlobe Announces Two New High-Rez Satellites
[+]
Geoplace tell us that DigitalGlobe is sending two new high-resolution satellites in space. From the article (for the first satellite): WorldView I, scheduled to launch no later than 2006, will be the most agile satellite ever flown commercially. The high-capacity, panchromatic imaging system features half-meter resolution imagery. With an average revisit time of 1.7 days and a swath width of 16 kilometers, WorldView I will be capable of collecting up to 500,000 square kilometers (200,000 sq. mi.) per day of half-meter imagery. WorldView I will also be capable of directly downlinking imagery to customer locations. The satellite will be equipped with state-of-the-art geo-location accuracy capability and will exhibit stunning agility with rapid targeting and efficient in-track stereo collection.
Sony Developing Gigapixel Sensor for Imaging
[+]
There is an ongoing discussion on Slashdot about this. Here is their summary: "Sony and the University of Alabama [in Hunstville] are working on a gigapixel resolution camera for improved satellite surveillance. It can see 10-km-square from an altitude of 7.5 kilometres with a resolution better than 50 centimetres per pixel. As well as removing annoying artefacts created by tiling images in Google Earth and similar, it should allow CCTV surveillance of entire cities with one camera. 'The trick is to build an array of light sensitive chips that each record small parts of a larger image and place them at the focal plane of a large multiple-lens system. The camera would have gigapixel resolution, and able to record images at a rate of 4 frames per second. The team suggests that such a camera mounted on an aircraft could provide images of a large city by itself. This would even allow individual vehicles to be monitored without any danger of losing them as they move from one ground level CCTV system to another.'" Update: 09/28 12:43 GMT by S :The Slashdot comments on the "7.5 km altitude orbit" claim underlines pertinent questions. In fact, we're talking about a UAV here, not really a satellite: "Mounted on the underside of an unmanned aerial vehicle, the gigapixel camera could provide almost real-time surveillance images of large areas for troops on the ground."
Oracle to Grant Direct Access to DigitalGlobe Imagery
[+]
This press release informs us Oracle 11g will soon give direct access to DigitalGlobe's imagery: "Via Oracle Spatial, DigitalGlobe will provide real-time access to its extensive image library for applications such as logistics, supply chain, mobile field services, business intelligence and asset management. With the release of Oracle Database 11g, DigitalGlobe allows advanced access to sample imagery data via OTN enabling Oracle customers to test-drive imagery in their business applications before making a purchase decision."

Any Geo reports that Digital Globe has made available the Worldview-1 imagery. From their summary : "WorldView-1, with its superior increase in capability and capacity, and QuickBird, DigitalGlobe’s other high-resolution satellite, together operate as the world’s highest-resolution commercial satellite constellation. The two satellites are collecting up to 900,000 square kilometers of new imagery per day, an unprecedented level that will enable faster turn-around on collection and rapid updating of DigitalGlobe’s ImageLibrary."
