How do I detect grid rasters with python?

PaulHuffman

I've been working on a script that searches down through a tree, finds GIS data, clips it by an Area of Interest poly, then writes it out in a new location duplicating the input tree structure. https://community.esri.com/thread/95511?sr=stream 

I only have this working for shapefiles and tifs.  I need to also get the grids,  but how to I detect a grid, a File System Raster, with python and arcpy?

I've been playing around with ListRasters, but I can't seem to make it do the os.walk.  ListRasters seems to ignore InputFolder, line 12, and only works on the env.workspace, set in line 8 (just as the documentation says).  Hmm,  do you think I need to reset the env.workspace right after the os.walk statement from each root,dirs combination?

# Import arcpy module
import arcpy
import os
#arcpy.CheckOutExtension("spatial")

# Set Geoprocessing environments
arcpy.env.scratchWorkspace = "c:\\avdata\\PythonTest\\ClipLidar\\Scratch"
#arcpy.env.workspace = "c:\\avdata\\PythonTest\\ClipLidar\TestData"
arcpy.env.workspace = "c:\\avdata\\PythonTest\\ClipLidar\\TestData\\Input\\Highest_Hit"
arcpy.env.overwriteOutput = True
clipshape = "c:\\avdata\\PythonTest\\ClipLidar\\AOIPoly_SP.shp"
InputFolder = "c:\\avdata\\PythonTest\\ClipLidar\\TestData\\Input"
#InputFolder = "c:\\avdata\\PythonTest\\ClipLidar\\TestData\\Input\\Highest_Hit"
#OutputFolder = "c:\\avdata\\PythonTest\\ClipLidar\\TestData\\Output"

#Find AOI extent
AOI = arcpy.mapping.Layer(clipshape)
AOIextent=AOI.getExtent()

#Find the input feature classes
for root, dirs, files in os.walk(InputFolder):
    rasterList = arcpy.ListRasters("*", "GRID")
for raster in rasterList:
        print raster
##    for name in files:
##        #Handle tifs
