I am doing a study where I am viewing the Gulf of Mexico before and after the Deepwater Horizon oil spill. I am looking to show the obvious oil slicks in the Gulf. I have done a bunch of research online on how to best view the oil slicks and many mention using thermal bands to view them since oil heats and cools differently than water. I am using Landsat 5 imagery, since the spill was in 2010.
Does anyone have any idea how I would go about this to get a result like this: https://imgur.com/Xs5bI2c
I am using ENVI, but am much more comfortable on ArcMap. Remote sensing is not my forte, so any help or techniques you would recommend to help would be amazing. Thank you!
