Space Imaging's (subsequently GeoEye) IKONOS satellite was the world's first commercial 1-meter remote sensing satellite. The potential applications of this high-resolution data were appropriate for a wide variety of customer segments. Data could be purchased by the square km for the customer's particular area of interest (with minimum order requirements). The 1-meter resolution of the panchromatic data enabled users to distinguish ground features as small as one meter. The accuracy and interpretability of the imagery made it ideal for mapping and analysis. IKONOS in addition collected 4-meter multispectral data, excellent for a variety of analysis applications. Space Imaging (GeoEye) also performed a technique called "Pan-Sharpening" which combined the spatial content of the 1-meter panchromatic data with the spectral content of the 4-meter multispectral data.
IKONOS was derived from the Greek word "EIKONA" which means "image." The IKONOS satellite system was built by Lockheed Martin Commercial Space Systems (Sunnyvale, California). The communications, image processing and customer service elements were built by Raytheon Company (Garland, Texas). The camera was built by Eastman Kodak (Rochester, New York).
In one-meter resolution images, objects that are one-meter in size on the ground can be distinguished, provided those objects are well removed from other objects and have separate and distinct visual characteristics. For example, objects such as swimming pools, cars and trucks, boats and tennis courts, which are all recognizable because of their context within their surroundings, can easily be detected. White stripes in parking lots and crosswalks are also visible because of the sharp contrast against the black asphalt. One-meter imagery cannot "see" individual people. A large number of people grouped together, on the other hand, could be seen, such as in a football stadium, but there, one would only know these are people because of the context.
TerraServer.com is an online source for overhead imagery. It has one of the largest online atlas of high-resolution satellite imagery and aerial photography. TerraServer.com gives everyone with Internet access the ability to search, browse and buy overhead images of the world around them. TerraServer started as a joint research project between Aerial Images, Inc., Microsoft, the USGS, and Compaq. The TerraServer concept grew out of the convergence of two needs. Aerial Images, Inc. wanted to sell imagery online and Microsoft Research needed a large database to demonstrate the capabilities of its new database software. Under the agreement Microsoft built the TerraServer application and agreed to host the SPIN-2 data and run the site for eighteen months following the formal site initiation (24 June 1998). Beginning in November of 1999, TerraServer.com began operating from Research Triangle Park, North Carolina, hosting, displaying, and selling SPIN-2 imagery and adding more imagery from new providers (including ORBIMAGE and UK Perspectives).
SPIN-2 imagery products are derived from the camera systems on Russian Cosmos spacecraft. These spacecraft were placed in orbit by Russian booster rockets. The orbiting satellites carry two cameras, allowing for the production of both 2 meter and 10 meter imagery. The two meter imagery is produced by the KVR 1000 camera system. This camera provide large area coverage in a single frame or scene. The individual scenes cover a usable area of 40 KM by 160 KM. The film was scanned to produce a digital image. The pixel size was 1.56 meters. The ground spacial resolution was 2 meters.
