I classified an image using Envi, however when importing the classified raster in to Arcmaps, the projection is off. I used the define projection to align it with the other layers, however it seems to have no effect even though the spatial reference and datum is the exact same as the other. Any thoughts as to what may be happening and how to correct it? Many thanks in advance.

What was set in envi? that seems to be the root source of the problem.

Also defining a projection will have no impact if it actually isn't in that coordinate system.  Define Projection should only be used when the coordinate system and projection are known, but just missing.  Project (tool) is what is needed if you want the data in a different coordinate system.

In what format is the classified image in Envi? Try converting it to TIFF using Envi, and then open it in ArcMap. Ensure to copy the supporting files as well, if any (like *.aux, *.ovr, etc.)
