How can I automate the workflow to manipulate a DEM with the ModelBuilder?

Hi

 

I like to use the ModelBuilder to automate the workflow of manipulating a DEM on special locations. The input is a polygon shape marking bridges and street dams.

 

Normally the workflow is

  1. CLIP (polygon and DEM) à Output: DEM_CLIP
  2. Change DEM_CLIP with RASTER TO POINT à Output: DEM_C_POINT
  3. Changing manually z values in the Attribute Table à Output: DEM_C_P_M
  4. Change DEM_C_P_M with POINT TO RASTER à Output: DEM_C_P_M_R
  5. Create a new Raster with MOSAIC TO NEW RASTER

 

I know, I must use Iterators. But I don’t know which one!

A problem will be the different z values. I can add an additional field at the polygon shape with the new z values or the program use the smallest z value at the Attribute Table.

 

Can someone help?

Can you clarify and provide more details on the exact changes you need? Is it the z value in the attribute table and those letters that you need appended to the file names?

Sorry for the late answer. The problem is solved. I downlodad die Arc Hydrolic Tool (yellow.esri.com - /archydro/archydro/setup/10.6/10.6.0.3/ArcHydroTools10.6x64/ ).
