I´m trying to open Landsat images at Geotiff with metadata in ENVI.

I have a dataset of 101 Landsat 8 images and I want to open all the images and then save them to do some band math either on ArcGIS for Desktop or ENVI.

Any idea in how can I do this task for the all batch at once?

I´m doing this to calculate the Normal Difference Snow Index (NDSI).

  • So what's the error, what about this isn't working? Are you trying to mosaic them or just convert the format? Jun 16 '15 at 3:10

    In ArcGIS you need to use the Model Builder with Iterate Rasters and various bits of Map Algebra. ENVI is not really suited for this kind of work without diving into IDL-scripting. Jun 16 '15 at 7:46
  • @MichaelMiles-Stimson I'm trying to apply all at once to all images.

  • @MikkelLydholmRasmussen Any idea of where can I find a IDL scripting tutorial or do you know how to do it?

  • What's the function(s)? Is it something that can be done in ArcGis with Spatial Analyst? Esri would be better for iteration than ENVI... so let's see if we can make a model for this. I've done NDVI in Esri, but being in Queensland (Australia) we have absolutely no call for snow index, therefore I'm not aware of the method to calculate this snow index. Jun 16 '15 at 21:24

This is the solution for you by using ENVI and timeseries analysis


  • I tried but I can't export each image or do band's math with this option. I have to process the images and then create shapefiles for each image with the snow cover. Do you know a way to do this with the time series? I have tried write a script with IDL but I don't manage the language, it is very tricky and different from Python.
