ERROR 000840: The value is not a Raster Layer

Question

I'm getting use FillSinks by ArcHydroTools but some problems are happen.

I use this code:

import arcpy
import ArcHydroTools
from arcpy import env
ws = env.workspace = r"C:\Users\fractal\Desktop\python_teste\projecaoMiriab2.tif"
output = "C:\Users\fractal\Documents\ArcGIS\Layers"
ArcHydroTools.FillSinks(ws, output)

and this error appears:

arcgisscripting.ExecuteError: Failed to execute. Parameters are not valid. ERROR 000840: The value is not a Raster Layer. Failed to execute (FillSinks).

I already tried to change my raster to format .lyr but it doesn't work.

What should I do?

Answer 1

This is a bit wonky:

ws = env.workspace = r"C:\Users\fractal\Desktop\python_teste\projecaoMiriab2.tif"

This code assigns the workspace, and the variable ws, to the folder housing your tif. So this line of code:

ArcHydroTools.FillSinks(ws, output)

tries to run the hydro tool with a folder as an input for a raster.

Your output looks like a folder. If so, add the name of your output raster to the output variable.

output = "C:\Users\fractal\Documents\ArcGIS\Layers\OutRaster"

A raster layer is different from a layer file, which you indicated when mentioning .lyr.

Use Make Raster Layer.

rast = r"C:\Users\fractal\Desktop\python_teste\projecaoMiriab2.tif"
arcpy.MakeRasterLayer_management(rast, "Miri")
ArcHydroTools.FillSinks("Miri", output)
