Ortho Product

RapidEye Ortho Products (Level 3A) are individual 25 km by 25 km tiles of RapidEye imagery orthorectified for customers who do not want to do their own image processing. Radiometric, sensor and geometric corrections have been applied to the data. The product accuracy depends on the quality of the ground control and DEMs used.

Geometric Corrections
  • Sensor-related effects are corrected using sensor telemetry and a sensor model, bands are co-registered, and spacecraft-related effects are corrected using attitude telemetry and best available ephemeris data.
  • Ortho-rectified using GCPs and fine DEMs (30m to 90m posting)
Horizontal Datum
WGS84
Map Projection
Universal Transverse Mercator (UTM)
Resampling Kernel
Cubic Convolution (default), MTF, or Nearest Neighbor
Product Framing
Image Tile (Image tiles are based on a worldwide, 24km by 24km fixed grid system. To each 24km by 24km grid square, a 500m overlap is added to produce a 25km by 25km image tile. Image tiles are black-filled 1km beyond the order polygon used during order placement. Tiles only partially covered by an image take will be also be blackfilled in areas containing no valid image data.An ESRI Shapefile of the RapidEye Level 3A tile grid can be downloaded here
