RapidEye Basic 5-band imagery with strip-based framing. This data set includes imagery from all RapidEye sensors.
Products Overview¶
The visual and analytic products are in GeoTIFF. The GeoTIFFs are resampled at 3 meters and projected in the UTM projection using the WGS84 datum. An alpha mask is provided as a binary color channel, and can be used to remove or hide low quality pixels near the periphery of a given scene. This mask compensates for effects due to vignetting, low SNR, or hot or cold pixels.
The RapidEye Basic product is the least processed of the available RapidEye imagery products. This product is designed for customers with advanced image processing capabilities and a desire to geometrically correct the product themselves. The products are available in GeoTIFF and NITF formats.
The RapidEye Basic Scene product is radiometrically and sensor corrected, providing imagery as seen from the spacecraft without correction for any geometric distortions inherent in the imaging process, and is not mapped to a cartographic projection. The imagery data is accompanied by all spacecraft telemetry necessary for the processing of the data into a geo-corrected form, or when matched with a stereo pair, for the generation of digital elevation data. Resolution of the images is 6.5 meters GSD at nadir. The images are resampled to a coordinate system defined by an idealized basic camera model for band alignment.
The radiometric corrections applied to this product are:
- Correction of relative differences of the radiometric response between detectors.
- Non-responsive detector filling which fills null values from detectors that are no longer responding.
- Conversion to absolute radiometric values based on calibration coefficients.
The geometric sensor corrections applied to this product correct for:
- Internal detector geometry which combines the two sensor chipsets into a virtual array.
- Optical distortions caused by sensor optics.
- Registration of all bands together to ensure all bands line up with each other correctly.
Product band order:
- Band 1 = Blue
- Band 2 = Green
- Band 3 = Red
- Band 4 = Red edge
- Band 5 = Near-infrared
