Lurker Posted January 16, 2017 Report Share Posted January 16, 2017 what level for your data? do you mean you try to run atmospheric correction and failed? please describe what you refer as "fail" what did you do? Quote Link to comment Share on other sites More sharing options...
mamadouba Posted January 17, 2017 Report Share Posted January 17, 2017 If you are referring to the simple "dehaze" options in Erdas, then you shouldn't expect perfection. Depending on the source and particulate, some haze cannot be removed. If you are referring to atmospheric correction of Level 2A, then you should be using Sen2Cor. http://step.esa.int/main/third-party-plugins-2/sen2cor/ Quote Link to comment Share on other sites More sharing options...
