Satellite Images


GRAS is an authorised distibutor of satellite images from Digital Globe (WorldView, Geoeye, Ikonos, QuickBird), Astrium (SPOT, Pleiades, TerraSAR), eGeos (Cosmo-Sky-Med, Radarsat) and RapidEye (RapidEye satellites). Because of the recent improvements in spatial resolution, very high resolution satellites are now a competitive alternative to aerial photography and field visits in many different applications.

Data can be purchased from the archive to match specific events or new acquisitions can be programmed at similar prices. This is a major advantage compared to aerial photography as images can be captured from any location in the world within 1-3 days. Please contact GRAS to order data or to receive a price quote for your area of interest.

Below is a list of the very high resolution data sets that GRAS offers from the WorldView, QuickBird, GeoEye, Ikonos, RapidEye, SPOT and Pleiades satellites. GRAS also offers medium resolution satellite images suitable for regional monitoring of the environment, agriculture, forestry and geology (Landsat, ASTER, IRS, ALOS etc). Furthermore, GRAS maintains Near Real Time delivery of medium and low resolution data for marine applications and environmental monitoring.

WorldView-2 This new and very promising high resolution satellite is presently being the only high-resolution, eight-band, multispectral commercial satellite. WorldView-2 collects multispectral imagery at 1.8 meter resolution and panchromatic imagery at 0.46 meters. And the combination of WorldView-2’s increased agility and high altitude enables it to typically revisit any place on earth in 1.1 days.

Quickbird

QuickBird QuickBird offers 60 cm resolution (panchromatic or pansharpened) and 2.4 m multispectral collected in a wide swath of 16.5 km which means that large areas can be acquired in one image.

GeoEye-1

GeoEye-1 GeoEye-1 was launched on 6 September 2008 and has the highest resolution of any commercial imaging system. It collects images with a ground resolution of 0.41-meters in the panchromatic or colour pansharpened mode. GeoEye-1, a polar-orbiting satellite, can revisit any point on Earth once every three days or sooner.

Ikonos

Ikonos Ikonos was launched by SpaceImaging in 1999 and was the first commercial satellite in the world to offer very high resolution satellite data. Ikonos offers spatial resolutions of 1 m panchromatic or pansharpened and 4 m multispectral. Digital elevation models (DEM) can be produced by tilting the camera in the along-flight direction.

RapidEye

RapidEye RapidEye is a 5 satellite constellation that offers a spatial resolution of 5 meters and 5 spectral bands. With its 5 satellites, the constellation provides the capability of daily revisits and is thus a good option for high resolution monitoring and large area coverage.

Pleiades

Pleiades Pleiades is a 2 satellite constellation that provides 4 band data at a 2 m resolution and panchromatic data at 0.7 m. Innovative technologies offers an exceptional ability to acquire along-track tri-stereo images feeding into the production of digital elevation models and high-performance classifications.

SPOT

SPOT Various SPOT sensors are currently in orbit with spatial resolutions from 20 m down to 1.5 metres. The SPOT archive dates back to 1986 when SPOT-1 was launched and this makes SPOT an ideal solution for time series analysis. Like the sensors listed above, the SPOT satellite can be programmed to acquire new images from any location on Earth.
