definition: The RapidEye constellation consists of five optical Earth Observation satellites with a swath width of 77 km wide at nadir and a ground resolution of 6.5 metres. RapidEye's sensors produce imagery in five spectral bands: Blue (440-510 nm), Green (520-590 nm), Red (630-685 nm), Red Edge (690-730 nm), and Near Infrared (760-850 nm). The system collects up to five million square kilometres of optical imagery every day for its archive and over one billion km2 every year. Over 70% of RapidEye imagery has a view angle of less than 10°, as the view angle is always less than 20°. The system also has the capability for daily revisit to any point on earth. Each of the five satellites are inter-calibrated to one another and to the ground so that images between satellites are indistinguishable from each other and are useful for bio-physical analyses of vegetation. Processing Levels: RapidEye 1B Basic product is radiometric and sensor corrected; and is the least processed of the RapidEye image products. This product is designed for customers who wish to do their own geometric correction and is accompanied by all the needed information for processing the data into a geocorrected form. The RapidEye Ortho product (L3A) is ortho-corrected using ground control and DEMs, then cut to the RapidEye tile grid. Each covers a 25 km by 25 km area with an overlap between adjoining tiles and is optimal for covering smaller project areas that require accurately referenced imagery.
