Modify Polymer scripts for CASI-1500 data
Posted: Fri May 21, 2021 10:10 am
Hello François,
As I wrote to you before, I want to apply the Polymer algorithm to my airborne data, i.e., the CASI-1500 data.
So far, I have calculated the parameters for the initial correction of the CASI-1500 reflectance (or radiance). The parameters include the total transmission of ozone (toz), Rayleigh reflectance (ρmol), direct transmission (T0), sunglint reflectance (ρgli), and the total transmission for atmospheric scattering (t).
By the way, I calculated these parameters only for one pixel inside my data and will apply them to the whole image. This may be different from what you did for the atmospheric correction of satellite images. Actually, I want to calculate these parameters for each pixel and then do per-pixel atmospheric correction. But for now, I want to do simple atmospheric correction of CASI-1500 data with Polymer.
For the next step, I want to apply the Polymer algorithm to my data. May I ask a question about how to modify the Polymer scripts? I am sorry that my question is not specific, because I have a difficulty to understand all the Polymer scripts. Could you tell me where to start and what should I modify?
Thank you in advance.
Kind regards,
Mengmeng.
