    Hello everybody, I am new in the forum so let present myself. I am a teacher in one university of China. I do research on methods to fill the data gaps in the ETM + imagery. I have try to fill the data gaps in the ETM+ imagery using landsat_gapfill.sav IDL programming. I want to know the details of the triangulation interpolation method in landsat_gapfill.sav. Anyone could give me some literatures of the triangulation interpolation method in landsat_gapfill.sav. Thank you!

    The one image triangulation method used in the Landsat Gapfill tool uses ENVI's DEM_BAD_DATA_DOIT to triangulate across image gaps. This routine uses IDL's TRIANGULATE function: https://www.harrisgeospatial.com/docs...
