Replacing data in raster using condition?
I have a raster dataset in ArcGIS displaying altitude.
I want to replace all values < 8 with value 8.
Other values have to stay the same. How can I do this?
I tried raster calculator, but I don't seem to get the expression right.

With the raster calculator, you can use the Con() statement(condiotion, value if true, value if false)
Con("raster" < 8 , 8, "raster")
