Ortho Take Product (level 3B)

The RapidEye Ortho Take Product (Level 3B) extends the usability of orthorectifed RapidEye products by leveraging full image takes and adjusting multiple images together to cover larger areas more accurately with fewer files. Each 3B product is a full swath-width orthorectified image that has been adjusted and trimmed to ensure the accurate placement and complete coverage.

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.
  • Orthorectified 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

Area based framing – a geographic region is defined by order polygon. The product width can be up to the full image swath as observed by all bands (~77 km at nadir) and up to a maximum length of 150 km. Images are cut to a minimum bounding rectangle and are black-filled 1 km beyond the order polygon used during order placement.
