Setting Mask from Parameter

anTonialcaraz

Hi everyone,

This may seem like an easy one but I cannot quite find the way:

When setting the environments, I want to use one of the parameters ("InputZ") as a mask for the different processes within the script.

It works fine like this:
arcpy.env.mask = r"D:\PROGRAMMES\LFP_Source_Rocks\ArcGIS\00_LFP_GLOBAL_MODEL\INPUT.gdb\Maas_Bathymetry"

but I want this:
arcpy.env.mask = (InputZ)

using ArcView 10.0

here is the beginning of the code:

import arcpy import string from arcpy import env arcpy.env.overwriteOutput=True from arcpy.sa import * arcpy.CheckOutExtension("Spatial")  # Set the output location, extent and Mask  OutLocation = arcpy.GetParameterAsText(0)  arcpy.env.extent = arcpy.Extent(-180.0, -90.0, 180.0, 90.0)  arcpy.env.mask = (InputZ)  # Input strings and variables  StageAge = str(arcpy.GetParameterAsText(1))  BSS = arcpy.Raster(arcpy.GetParameterAsText(2))  InputLatitude = arcpy.Raster(arcpy.GetParameterAsText(3))  InputZ = arcpy.Raster(arcpy.GetParameterAsText(4))  InputCountrylines = arcpy.GetParameterAsText(5)  NPPEquation = str(arcpy.GetParameterAsText(6))

Any help will be greatly appreciated.

Many thanks

Toni,

Did you remove the 'arcpy.Raster' from the arcpy.GetParameterAsText?  Also, what data type are you setting for this parameter in your script tool?  For example, I had the following script:

import arcpy arcpy.CheckOutExtension("Spatial") from arcpy import env env.workspace = r"C:\data\raster\dem"  InputZ = arcpy.GetParameterAsText(0)  env.mask = InputZ  arcpy.Slope_3d("example","Slope","DEGREE","1")

I then added this to a toolbox and set the parameter to a Raster Dataset:

[ATTACH=CONFIG]30030[/ATTACH]

When running the tool, the slope masked the raster I chose.
