Inserting a script in Model-Builder ArcGIS

Recommended Posts

Hello all,

I am looking for some tips about inserting a script in the model-builder...

I am actually building a model in the Arc-GIS model-builder. At one point I would like to insert a script that crosses information from two layers at one point of the model with a output layer, that will be used further along.

In Arcmap, I added the script with a right-click in my toolbox > add script...

After loading my script, I applied the following parameters:

-Two inputs, referring my layers that I use in the script (raster layer type) - One output, for the result (raster layer type)

I then go to my model and drag my script into it. I connect my two layers as inputs with the arrow and specify the output file name. All seems ok as the boxes appear with the correct colors.

I have to specify that I am working with a variable folder %folder% so I added that in my script.

When I validate my model it goes all blank, because it cannot find the input layers, as they are created in the model.

Can anybody help me please?

PS: Here is my script:

# ---------------------------------------------------------------------------
# calculator.py
# Created on: 2012-11-15 16:59:11.00000
# (generated by ArcGIS/ModelBuilder)
# Description:
# ---------------------------------------------------------------------------[/background][/font][/color]
# Import arcpy module
import arcpy
# Check out any necessary licenses
arcpy.CheckOutExtension("spatial")

# Local variables:
raster = "%Dossier%\Erosion.gdb\raster"
# Process: Calculatrice raster
arcpy.gp.RasterCalculator_sa("Con((\"%Surf_Drainee%\" > 12) & (\"%Surf_Drainee%\" <= 80) & (\"%Pente_Rclass%\" <= 24), \"%Pente_Rclass%\" + 1, Con((\"%Surf_Drainee%\" > 80) & (\"%Pente_Rclass%\" < 24), \"%Pente_Rclass%\" + 2, Con((\"%Surf_Drainee%\" > 80) & (\"%Pente_Rclass%\" == 24), \"%Pente_Rclass%\" + 1, \"%Pente_Rclass%\")))", raster)

Try these,

-place the raster outside gdb and call the full name with extension (ie- raster.tiff)

-try the script on different raster layer without variable folder declaration and check if it works

-check if everything is ok with the raters (ie - projection).

@ Maxsigma

If you still have the problem, can help in this regards.

In my first look, I guess you have problem in defining path. Use "\\" or "/" instead of "\" like: "c:\\Temp\\Demo.gdb\\raster" or "c:/Temp/Demo.gdb/raster" etc.
