Trying to write a python script to batch Aggregate a bunch of different rasters. get a Parsing Error Syntax error for line 11.

# Batch Aggregate raster tool
import arcpy
from arcpy import env  
from arcpy.sa import *

env.workspace = r"C:\rasters"
out_workspace = r"C:\rasters\agg"

rasters = arcpy.ListRasters()

for raster in rasters
    outAggreg = Aggregate(raster, 10, "MEAN")
    outAggreg.save(out_workspace, raster + "_agg")

You are missing a colon after rasters. –  Paul Jul 13 '13 at 20:26

Try the following changes:

# Batch Aggregate raster tool
import arcpy, os
from arcpy import env  
from arcpy.sa import *

env.workspace = r"C:\rasters"
out_workspace = r"C:\rasters\agg"


rasters = arcpy.ListRasters()

for raster in rasters:
    outAggreg = Aggregate(raster, 10, "MEAN")
    outAggreg.save(os.path.join(out_workspace, raster + "_agg.tif"))

It ran, but this time I get an error: RuntimeError: ERROR 010093: Output raster format UNKNOWN is unsupported. The input raster is an ECW and aggregate can't output that - it can output TIFFs though. –  detroit_hc Jul 13 '13 at 20:40

Try adding the .tif extension to the output path. –  Aaron♦ Jul 13 '13 at 20:51

Bingo. out_workspace, raster + "_agg.tif" Thanks for the help! –  detroit_hc Jul 13 '13 at 20:54
