Hello, I am currently working with Landsat 7 ETM+ data for a school project and I have to fill the gaps in the images before further processing. I read somewhere that it is possible to download an ENVI gap fill extension and use this .sav file to fill the gaps in the software, but I somehow don't find the link to download this extension. I tried to look 8it up on google and on the Harris website as well. If anyone knows where to find this download or the .sav file, I would really appreciate your help! Thanks, Jonas

El producto de la corrección del gapfill puede ser utilizado para análisis espectral? o para realizar un preprocesamiento?

When filling gaps, you are using parts of another image or you are generating data to fill in the gaps using triangulation or other method. I would use this result in spatial and visual analysis but it is likely not suitable for spectral analysis.
