Very High Resolution Optical Imagery

The launch of the IKONOS satellite (1999) made history with the world’s first 1 meter commercial remote sensing satellite. IKONOS produces black-and-white (panchromatic) images with 82-centimeter resolution and multispectral imagery with 4-meter resolution. Imagery from both sensors can be merged to create 1-meter colour imagery (pan-sharpened). The more than 300 million km² of imagery that IKONOS has collected over every continent is being used for national security, military mapping, and by regional and local governments.


The GeoEye-1 satellite launched in 2008 is the world's highest resolution commercial earth-imaging satellite. The GeoEye-1 satellite collects images at nadir with 0,41-meter panchromatic (black & white) and 1,65-meter multispectral (blue, green, red and near infra-red) resolution. The detail and geospatial accuracy of GeoEye-1 imagery further expands applications for satellite imagery in every commercial and government market sector. The positional accuracy is the best of all commercially available satellites, namely 3 meters.

DigitalGlobe’s QuickBird satellite provides very high resolution panchromatic and multispectral imagery. QuickBird provides images at 61 cm (panchromatic) and 2,44 m (multispectral) resolution. Its large swath width, combined with ample on‐board storage and geolocational accuracy, allows it to efficiently and accurately image large areas of the globe. The QuickBird spacecraft is capable of acquiring over 75 million square kilometers of imagery data annually.


The WorldView-1 satellite, launched by DigitalGlobe, is the first satellite equipped with state-of-the-art control moment gyros, which provide stunning agility, rapid retargeting and efficient in-track stereo collection. The WorldView-1 spacecraft is capable of collecting up to 750 000 square kilometers of 50 cm resolution panchromatic imagery per day. The images are only available in black and white since there is no multispectral sensor on board the satellite.

WorldView-2 is the first commercially available 8-band multispectral satellite. The WorldView-2 spacecraft is capable of collecting up to 975 000 km² of 50 cm panchromatic and 2 m 8 band multispectral imagery per day. Beside the four standard bands (blue, green, red & near infrared), the imagery also contains 4 additional colours (red edge, coastal, yellow and near infrared 2).

Also SPOT5, Formosat-2 and Kompsat-2 are Very High Resolution sensors. For more information about these sensors please take a look at “Spot Distributorship”
