I have several flood depth rasters (floating point) from different flood studies and a dem (floating point).
The idea is to generate a flood planning layer (flood depth raster + 0.5m) using the flood depth rasters and a dem (floating point).
In raster calculator I did "Con("flood_depth_raster","dem")" which gave me the extent of the flood depth raster with the dem values.
Does anyone know a way to add 0.5m to this and fit to the dem?
Then i will create a flood planning level polygon from the raster to use in the gis in further analysis.
