What tools in ENVI should I use to perform post-classification sorting of Landsat 8 image? My goal is to incorporate ancillary data (i.e. DEM) in the post-classification process to enhance the accuracy of the supervised classification. My study area has 7 classes, 6 of these are vegetation types. I found that in some studies, the use of ancillary data could be helpful in improving land use discrimination and classification accuracy.
Can someone please suggest the steps and/or recommend studies that used ENVI for this purpose?
Thank you!

This is a very simple process. Take any suitable DEM such as SRTM and make a layers stack image with landsat bands and this DEM. use supervised classification. Some of the studies like singh et al. in Mauling national park may also be reffered.Article Vegetation cover type mapping in Mouling National Park in Ar...
Dharmendra Singh thanks for sharing this. The process you mention seems to refer the use of ancillary data during classification, not after.
Yes you are right Dannica.. sorry I missed that. than you can convert the null values basically into 0 or below 0 in to some logical number well ahead of your total number of classes.
