RapidEye Orthorectified 5-Band Imagery as 25km x 25km UTM Tiles. This data set includes imagery from all RapidEye sensors.
Products Overview¶
All ortho tile products are provided in GeoTIFF format. The ortho tile product GeoTIFFs are resampled at 3.125 meters and projected in the UTM projection using the WGS84 datum. An alpha mask is provided as a binary color channel. The alpha mask can be used to remove or hide low-image-quality pixels near the periphery of a given scene. The alpha mask compensates for effects due to vignetting, low SNR, or hot or cold pixels.
The RapidEye Ortho Tile products offer RapidEye Satellite imagery orthorectified as individual 25 km by 25 km tiles. This product was designed for a wide variety of applications that require imagery with an accurate geolocation and cartographic projection. It has been processed to remove distortions caused by terrain and can be used for many cartographic purposes.
The RapidEye Ortho Tile products are radiometrically, sensor and geometrically corrected and aligned to a cartographic map projection. The geometric correction uses fine DEMs with a post spacing of between 30 and 90 meters. GCPs are used in the creation of every image and the accuracy of the product will vary from region to region based on available GCPs. RapidEye Ortho Tile products are output as 25 km by 25 km tiles referenced to a fixed, standard RapidEye image tile grid system.
Product band order:
- Band 1 = Blue
- Band 2 = Green
- Band 3 = Red
- Band 4 = Red edge (analytic products only)
- Band 5 = Near-infrared (analytic products only)
