rodloc Posted July 14, 2011 Report Share Posted July 14, 2011 i have this equation to use in ENVI 4.8. I do not have access to IDL so i cannot do it by using that. what i am wondering is if it possible to run the equation through Band Math Quote Link to comment Share on other sites More sharing options...
Administrators EmperoR Posted July 14, 2011 Administrators Report Share Posted July 14, 2011 hem, are you using ENVI 4.8 from here or using legal license ? ENVI 4.8 by LOMEX if Im not mistaken have access to IDL too regards, ADMIN Quote Link to comment Share on other sites More sharing options...
rodloc Posted July 14, 2011 Author Report Share Posted July 14, 2011 i have a legal license but whenever i use there support they are very limited answers. so i thought i would see if the gis community has done anything like this with ENVI.

Administrators EmperoR Posted July 14, 2011 Administrators Report Share Posted July 14, 2011 any error that occured? I have ENVI installed on my home PC, I will try this night to see what really happen, but it use LOMEX solution normally, by accessing Basic tools>Band Math you can access this function see here : [hide] http://geol.hu/data/online_help/Band_Math_Basics.html [/hide] or [hide] http://www.dsr.inpe.br/tutorial/tut18.htm [/hide] Quote Link to comment Share on other sites More sharing options...

rodloc Posted July 14, 2011 Author Report Share Posted July 14, 2011 the real problem occurs when i do equation number 4. i can do equation 3 alright and probably 2 if i had the result of 4. but i am not sure how i do the integral symbol with band maths Quote Link to comment Share on other sites More sharing options...
