◆ optimizeModel()

bool ossimplugins::ossimGeometricSarSensorModel::optimizeModel	(	const std::list< ossimGpt > &	groundCoordinates,
		const std::list< ossimDpt > &	imageCoordinates
	)

virtual

This function optimizes the model according to a list of Ground Control Points.

The input list of GCPs is appended to the one present in memory. An inverse localization of each ground GCP is performed. The error between localized GCPs and actual image coordinates is then computed and modeled by a linear model on each dimension. The time and range estimations are updated accordingly.

Parameters

groundCoordinates	: input GCP ground coordinates
imageCoordinates	: actual image coordinates corresponding to input groundCoordinates
