Hi,I am trying to build pyramid for NED DEM 30 meter raster files (and eventually mosaic them). I have a main directory and many subfolders. Please see the file attached. The problem is that I can't set it up so the program can read the raster files in the subfolders. I think I am missing a command line or something here. Any help would be very appreciated. Here is the code that I wrote so far. Note that I used lots of 'print' coz I wanted to know if the program reads the files.# Import system modules import sys, arcpy, os, time, os.path from time import time, ctime from arcpy import env from arcpy.sa import * print "The START time is:",ctime(time()) # Check out the ArcGIS Spatial Analyst extension license arcpy.CheckOutExtension("Spatial") # Main Directory arcpy.env.workspace = "Y:/Work/NED30M" inputDirectory = os.listdir(arcpy.env.workspace) # Loop through directory & files #Local variables: for inputFolder in inputDirectory: print "<<<----------------------------------------->>>" print "Input Directory is: " + str(inputDirectory) print "Input Fodler 01 is: " + str(inputFolder) inputFolderFiles = arcpy.ListFiles(inputFolder) RasterFiles = arcpy.ListRasters() for inputFiles in inputFolderFiles: print "Input FolderFiles are: " + str(inputFolderFiles) print "Input files are: " + str(inputFiles) print str(RasterFiles) + " ... Why Can't Read? ... " for filename in RasterFiles: arcpy.env.workspace = os.path.join (inputFolder, filename) print "Filename is: " + str(filename) print("\n Processing: " + filename) print "Input Raster is: " + str(filename) ## # Process: Build pyramid ## arcpy.BuildPyramids_management(filename) print "***" print "DONE!!" print "The FINISH time is:",ctime(time()) and here is the output:IDLE 2.6.5 >>> ================================ RESTART ================================ >>> The START time is: Fri Feb 15 16:22:08 2013 <<<----------------------------------------->>> Input Directory is: [u'n35w090', u'n35w091', u'n35w092'] Input Fodler 01 is: n35w090 Input FolderFiles are: [u'n35w090'] Input files are: n35w090 [] ...

Thank you very much,Risa
