Member Data Documentation

int GDALPansharpenOptions::bHasNoData

Whether the panchromatic and spectral bands have a noData value.

double GDALPansharpenOptions::dfNoData

NoData value of the panchromatic and spectral bands (only taken into account if bHasNoData = TRUE).

This will also be use has the output nodata value.

GDALPansharpenAlg GDALPansharpenOptions::ePansharpenAlg

Pan sharpening algorithm/method. Only weighed Brovey for now.

GDALRIOResampleAlg GDALPansharpenOptions::eResampleAlg

Resampling algorithm to upsample spectral bands to pan band resolution.

GDALRasterBandH GDALPansharpenOptions::hPanchroBand

Panchromatic band.

int GDALPansharpenOptions::nBitDepth

Bit depth of the spectral bands. Can be let to 0 for default behaviour.

int GDALPansharpenOptions::nInputSpectralBands

Number of input spectral bands.

int GDALPansharpenOptions::nOutPansharpenedBands

Number of output pansharpened spectral bands.

int GDALPansharpenOptions::nThreads

Number of threads or -1 to mean ALL_CPUS.

By default (0), single threaded mode is enabled unless the GDAL_NUM_THREADS configuration option is set to an integer or ALL_CPUS.

int GDALPansharpenOptions::nWeightCount

Number of weight coefficients in padfWeights.

double* GDALPansharpenOptions::padfWeights

Array of nWeightCount weights used by weighted Brovey.

GDALRasterBandH* GDALPansharpenOptions::pahInputSpectralBands

Array of nInputSpectralBands input spectral bands.

The spectral band have generally a coarser resolution than the panchromatic band, but they are assumed to have the same spatial extent (and projection) at that point. Necessary spatial adjustments must be done beforehand, for example by wrapping inside a VRT dataset.

int* GDALPansharpenOptions::panOutPansharpenedBands

Array of nOutPansharpendBands values such as panOutPansharpenedBands[k] is a value in the range [0,nInputSpectralBands-1] .
