I have calculated atmospherically corrected reflectance values for Landsat 8.

From that, I am getting correct values of NDVI in QGIS, but for EVI I am not getting the correct values. For some images it goes beyond 1 and for others it shows black output in QGIS.

I am using the EVI formula derived for MODIS.

    Could you please include the EVI implementation you used in QGIS? – Aaron Aug 6 '14 at 19:27
EVI = 2.5 * (NIR-Red)/(NIR+6*Red-7.5*Blue+1) 

I have used this formula in the raster calculator of QGIS.
