Using Raster to Point conversion tool in ArcMap is the first thing that comes to mind, it should give you a point in for every raster cell you have (placed in the middle of the cell) and then you can edit the points as you want.
You could also take a look at this for alternative methods.
There is also a Raster to Vector tool in ENVI that you can try, though I'm not sure how well it deals with point conversions.
