I am working in ENVI 4.7. I try to convert DN to Surface reflectance, but still I didn't find out the solution. Is there any tool for conversion?
I've searched the web and various files for this conversion and found out that ResearchGate is a website that handles this stuff. They even created a DOC with the instructions on how to perform the conversion from DN to reflectance. You can download the file using the link posted below.

If you don't have a document processor installed, use the following one called OpenOffice: http://openoffice-org.software.informer.com/
