Resampling algorithm
|
Level 1G System Corrected images are resampled to a regular output grid. The resampling algorithm specifies how the input pixels are sampled: how many and how they are weighted. The available algorithms are:
Nearest Neighbour
The radiometric value of the output pixel is set equal to the value of the nearest input pixel in the original geometry. This algorithm preserves to the maximum the original radiance values.
Cubic Convolution
The radiometric value of the output pixel is interpolated using the values of its 16 nearest neighbours in the original geometry. This algorithm produces a better looking image, but changes the original satellite
