Good afternoon. After hitting DRA on composite map it dissappears, becoming "mosaic type". Could you please tell why it's happening?

[@MarianaLuzCarlosPalomino]

Hi I have a question. Are you using the TIF format or the JPG of the terrain?

[@GEO2004]

I think the format doesn't matter

Sir if we get magenta,cyan and yellow colour what would it indicate,and if I am looking for hydrocarbon(methane) microseepages alterations how am I going to point out the alterations.

[@GEO2004]

you should learn about spectral curve interpretation if you want to know what those color indicates,

[@surmanibaxla8789]

Thank u sir

[@azranhazemijusoh6770]

what if I want to do the same thing for tropical areas with thick vegetation such as in Malaysia? can this work?

[@GEO2004]

No.

[@azranhazemijusoh6770]

Could this work in tropical regions with thick vegetation?

[@GEO2004]

No. Radiation signals from the sun won't be able to penetrate the vegetation in SWIR bands
