Me262 Posted November 16, 2014 Report Share Posted November 16, 2014 I am looking to "combine" several hyperspectral images I have into 1 image. Reason being is that I want to create ROI's in order to do supervised classification. However, these training areas must be from several images. I need to basically create 1 ROI classified as "good", another ROI as "bad" and the 3rd I'l have everything else. Not sure how to do this unless I somehow combine all images into 1. ENVI 5+ is nice and you can open all the images into 1 window, and they kind of look combined, but when you do the ROI's, they are still separated into each image.

Administrators EmperoR Posted November 17, 2014 Administrators Report Share Posted November 17, 2014 combining in ENVI as you said basically only stacking, which is put many images into one data with so many layers, you can do this with many remote sensing software, standard tools, but they still in separate images Quote Link to comment Share on other sites More sharing options...
Me262 Posted November 17, 2014 Author Report Share Posted November 17, 2014 (edited) Thanks for the reply. Forgot to mention that the images are basically "tiles" that together create a map of a municipality. They don't actually "stack" on top of each other. Basically like a puzzle, got several pieces and I'd like to create only 1 piece, so then I can run all my analysis onto that 1 image file. Otherwise I cannot do classification with ROI's from different images (at least the tool only allows me to select 1 image from what I noticed). I only have ENVI to work with, and cannot find a way to either "glue them together" or run analysis using each separate images into each analysis I want to run (in my case, supervised classification) Edited November 17, 2014 by Me262 Quote Link to comment Share on other sites More sharing options...
3dbu Posted November 17, 2014 Report Share Posted November 17, 2014 if are title should make a mosaic, but is necessary to have more information about date of each title , but could make a histogram match. for make the mosaic and then make all you classification analyst. regards Quote Link to comment Share on other sites More sharing options...
