I have a series of linear data sets; roads and rivers.

  I have buffered these to make them integratable with a raster file and then converted from a polyline to a raster.

But i cant get it to add to the raster image, which is a land cover classification. I've tried to mosaic it with the original raster but it doesn't work.

How should I do this?
