This correction is optional. It can be used when considered that there is some influence of haze on the imagery. The example has been prepared using pre-loaded routines in ERDAS Imagine 2011.
- Go to RASTER → RADIOMETRIC → HazeReduction
- Load the desired image in “Input File”:l519971016_stack_cut_corr
- In “Output file” create a folder with the name, e.g., CORRECCION HZ
- Save the image as: l519971016_stack_cut_corr_h
- Go to ” Method” and choose “Point Spread“
- On “Point Spread Type” select “Low” and then OK.
