Detailed Description

Mosaic of two rasters linked by a tie-points set. strategy.

Author:

Emiliano F. Castejon <castejon@dpi.inpe.br>

Note:

The required parameters are:

Parameters:

input_raster1	( TePDITypes::TePDIRasterPtrType ) - Input raster 1 (this will be the reference raster).
input_raster2	( TePDITypes::TePDIRasterPtrType ) - Input raster 2.
channels1	( std::vector< unsigned int > ) - The channels to process from input_raster1.
channels2	( std::vector< unsigned int > ) - The channels to process from input_raster2.
output_raster	( TePDITypes::TePDIRasterPtrType ) - Output raster.
trans_params	( TeGTParams ) - Geometric transformation parameters.

Note:

The optional parameters are:

Parameters:

blend_method	( TePDIBlender::BlendMethod ) - Blending method (default: TePDIBlender::NoBlendMethod).
interp_method	( TePDIInterpolator::InterpMethod ) - Interpolation method (default TePDIInterpolator::NNMethod) .
dummy_value	(double) - A dummy pixel value for use in pixels where no data is available.
auto_equalize	( int ) - If present ( any value ) auto-equalizing will be made ( using overlap area reference ).

Note:

The output_raster parameters will take the reference raster parameters.

The output raster data type will be automatically to fit the range of both input rasters.

Transformation tie-points: TeCoordPair::pt1 are raster 1 indexed (line, column) coordinates and TeCoordPair::pt2 are raster 2 indexed (line, column) coordinates.

Examples:

TePDIMosaic_test.cpp.
