Im totally not understanding the raster calculator and how to build statements. I have a stream network and some lakes that I have build and put some buffers around. I need to covert my raster verisons of my buffers to a 1,0 raster (with a value of 1 for areas outside of the buffer and 0 within it). I need to use the con and isnull function, but I have no idea on how to bulid that statement. can anyone help me?
