I am looking at a region in the Alaskan tundra, there are plenty of small water bodies in my scene.
I need to mask these bodies, so that I can perform a surface temperature/emissivity normalization scene on only these water bodies. The ultimate product is to look at the original scene, and overlay the temperature masks unto the bodies of water.
How can I do this?
Edit: I am relatively new to ENVI, but I have tried doing a NDWI with band math.. It created a scene in which it identified possible water bodies in white and the rest in black. I could not figure out how to create a shapefile out of the white bodies it identified..
I have also considered classifying the water bodies but I am not sure how to go about this and ultimately create a mask.
I am working with Landsat 8 Data.
