Optical Images

Optical sensors allow you to have a realistic image (visible domain) or almost (near infrared), but they are blind at night and under cloudy cover. To characterize an agricultural landscape, optical images will be adapted.

Pleiades 1 (1A, 1B)

Order Pleiades 1 (1A, 1B)

Description

Pleiades 1(1A,1B)

Fully funded, manufactured, owned and operated by Airbus, the Pleiades satellite constellation provides very high resolution optical imaging that offers an extremely high level of detail. With four satellites of the same resolution of 50 cm and ultimate reactivity. The system provides both panchromatic and multispectral products with one of the largest footprints. The agility of the Pleiades allows them to be very responsive to end-user requests and to obtain and provide data in record time. Designed for civilian and military users, the system is particularly suited for emergency response and change detection

SPOT 6,7

Order SPOT 6,7

Description

Spot 6,7

Ville d'Oyem, Gabon

SPOT-6 and SPOT-7, two optical Earth observation satellites with a resolution of 1.5 m / pxl, were designed to continue the SPOT-5 mission to obtain high-resolution broadband images and provide satellite data until 2023. The construction was initiated by Spot Image of Toulouse (France) and EADS Astrium in 2008, and officially announced in mid-2009 by Eric Beranger, CEO of Astrium Services. SPOT 6 was successfully launched on 9 September 2012 by the Indian polar satellite launcher and was followed by SPOT 7 on 30 June 2014. The technology allows users to obtain high-quality ortho-images as well as broadband satellite images that complement the very high-resolution Pleiades data.
