Product Description

WorldView-1

WorldView-1 is a commercial earth observation satellite owned by DigitalGlobe and was launched in September 2007.The WorldView-1 satellite offers a high-capacity, panchromatic imaging system which features 0.46 m resolution imagery.

Operating at an altitude of 496 kilometres, WorldView-1 satellite has an average revisit time of 1.7 days and is capable of collecting up to 750,000 square kilometres (290,000 square miles) per day of half-metre imagery. The satellite is also equipped with state-of-the-art geo-location capabilities and exhibits stunning agility with rapid targeting and efficient in-track stereo collection.

The WorldView-1 sensor boasts one of the largest archives of high-resolution imagery, and was the first 0.5 m resolution sensor on the commercial market. While only capturing panchromatic imagery, this sensor is a great option for historical views of areas, and has collected an extensive amount of stereo pair imagery that can be used for elevation model creation.
