Dear All,
I am trying to calculate Enhance Vegetation Index (EVI) using LANDSAT 8 images in ERDAS model builder and Arc GIS. But after processing i getting the totally black image. I not able to understand where goes wrong.
For Enhance Vegetation Index (EVI) calculation i am using input as a direct extract image from the rar file.
I have tried to FLOAT (Single, Double) data type as output file but problem still same
So request to all please provide your valuable guidance to complete my task.
Below i have attached model and output screen shot.
I am using ERDAS 2013 and ARC 10.1.
Thank you
Shouvik Jha
There is a previous discussion about EVI here.

Thank you Eric Ariel L. Salas. I followed this process before posting here but problem still same in ARC GIS and ERDAS.
Check the following thread, although it was asked for ENVI, but you can find some information related to your stuff:

You can use Raster Calculator in ArcGIS to verify the formula you were using.
Shouvik, which formula did you use for EVI in ERDAS Imagine Model Maker and ArcMap Raster Calculator? May be some of us can rectify the error if you type the formula that you used for EVI. Which reference article are you using for EVI?
