I have the following script:
#Import ArcPy site package import arcpy from arcpy import env from arcpy import Raster from arcpy.sa import ZonalStatistics from arcpy.sa import CreateConstantRaster # Set Environment Workspace ws = env.workspace = "MY_WORKSPACE_PATH\\FGD.gdb" # Set Environment Raster Cell Size env.cellSize = 10 # Check out ArcGIS Spatial Analyst extension license arcpy.CheckOutExtension("Spatial") # Get Parameters as Text rasters = arcpy.GetParameterAsText(0) inputRasters = rasters.split(";") inZoneData = arcpy.GetParameterAsText(1) zoneField = arcpy.GetParameterAsText(2) # The constant raster = 0 addedRaster = CreateConstantRaster(0) # Process each raster string for raster in inputRasters: addedRaster = addedRaster + Raster(ws + "\\" + raster) # Execute Zonal Statistics zoneStats = ZonalStatistics(inZoneData, zoneField, addedRaster, "MAXIMUM", "DATA") # Save the output zoneStats.save(ws + "\\" + NewTest_12102011")
I have imported the script as a script tool in ArcMap, my parameters are in the correct order and have the correct attributes (this script works when I have, for example, just two raster inputs as parameters). The input rasters are referenced as a String (this tool will eventually be used as a Geoprocessing Task, so I cannot use rasters a input directly). The problem I have is that when I open the tool, there is no way for me to input anything into the first parameter.
To provide some clarity: each value that could be entered into the parameter would be the name of a raster inside the geodatabase. For instance, say the user enters "rasterOne" and "rasterTwo". This would refer to MY_WORKSPACE_PATH\FGD.gdc\rasterOne and MY_WORKSPACE_PATH\FGD.gdc\rasterTwo, which are then cast to a Raster object with
Any suggestions would be great. Thanks.
