I am trying whether it is possible to view hot steam sources like power plant cooling towers and resulting cloud using satellite images. I was advised to try Landsat (needed free data for initial research)
I downloaded two Landsat 7 images from various regions with two big power plants (about 4 cooling towers each) and tried to use common band combinations (3-2-1, 4-3-2, 4-5-3, 7-4-2, 5-3-1) in SAGA GIS to create composite images. I though it could show the vapor cloud at least near the power plant but I am not able to identify it. It is possible to somehow filter the images and remove most of the background to highlight what I need?
thanks
PS: the goal is to get an approximate result whether it has sense to start more detailed research in this area or not. I have QGIS and SAGA on all of my computers.
