This question already has an answer here:
I am looking for a Landsat gap fill method for quantitative data analysis. The best I have found is a reference to a method called "single file gap fill triangulation" using in ENVI, but am unsure how this method was carried out and I couldn't find a tool in ENVI.
I don't normally use ENVI, is there method or documentation for preforming this gap fill in ENVI v5.0? Or another method out there?
