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.
All RapidEye image products come with a reduced resolution browse image, XML metadata file and Unusable Data Mask (UDM) file. The UDM file is a reduced resolution, geo-referenced raster file showing areas covered by clouds, blackfill or missing data. The RapidEye 3A Ortho product is delivered in a single GeoTIFF file.
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.
