Topographic Normalization in ERDAS Image
When I using atmospheric correction with ATCOR tool in ERDAS
image, it was not always answer and give me nice result of corrected imaginary
(I used to Landsat satellite imaginary and ASTER GDEM 30m), especially for
mountainous area.
Back then, my lecture ever told me, that to predicting potential burn
area using Landsat satellite imaginary, we have to correcting the image first
with atmospheric or radiometric correction. Minnaert Topographic Normalization is the one of many method and tools to
execute this correction.
This simple one does not spend many time
to processing ( I need less than 1 minute J) , and more
over we only need 3 files / data as below: 1.Satellite
imaginary 2.Metadata
of satellite imaginary ( value of Solar / Sun Azimuth and Elevation) 3.Elevation
imaginary
