ich was searching for my problem but was not able to find a solution.
I got a .dem package of Alaska and add them as a layer in ArcMap.
What I see is this:
Is there a way to fix this and get a clean image?
Thanks alot! santos
edit: I found out how to do it (mosaic to new raster) - but stuck on a new problem. 🙂 The result of the new raster is much brighter and the white is "burned out". the peaks of mountains become flat... I added an example. Anybody can help with that?

When you mosaic your rasters to a new file. you change the lowest low value and the highest high value, so the stretched display of data needs to cover a larger range. You could set the range explicitly by setting the stretch type to Minimum-Maximum, and setting the statistics to "from custom settings". Regards, Jim
The default is to use the coarsest cellsize for the output, so perhaps you have a file at a different resolution that is causing some downsampling. You can set the output cellsize in the environment tab.
