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.
