GeoSpot

GeoSpot_3

GeoSpot is for high-accurate 3D georeferencing of linear array stereo-images via sensor-dependent orientation model. The existing version of Geospot is available for reaching sub-pixel accuracy at ground control points (GCPs) and ~1 pixel at independent check points (ICPs) updating (i.e. compensating or adjusting) the interior and exterior orientation parameters using GCPs for SPOT-5 HRG level 1A images. It has some originalities that

  • Estimation of the cross-correlation between interior and exterior orientation parameters.
  • Statistical validation of exterior orientation parameters,
  • Solving ill-conditioned Jacobian matrix of exterior orientation parameters.
