I have a problem with combining two DEMs.
I have one TIFF DEM where river bed is not accurate and I have point cloud file of river bed with accurate data.
So, I need to upade TIFF DEM with this point cloud file.
Is this possible to do in Erdas Imagine?
Thank you in advance,

Terrain Prep Tool provides an option to merge DTM datasets.
What I would probably suggest is first setting to NoData the area in the (inaccurate) raster DEM corresponding to the extent of the accurate point cloud data. Then feed that edited raster and the point cloud into Terrain Prep Tool.
