Problem in saving output raster in a specific output folder with correct name

ShouvikJha — Sat, 11 Dec 2021 23:08:05 GMT

I am trying to save output raster in out_ws folder path with name r001_EVI, r002_EVI so on... but output raster goes to the main folder (MODIS_SURFACE_RF2012) with such output name rEVI_001_EVI.

How to link it with desire location with output name e.g r001_EVI, r002_EVI so on.

env.workspace = 'D:\MODIS_SURFACE_RF2012\EVI'
out_ws = 'D:\MODIS_SURFACE_RF2012\EVI1'
rasters = arcpy.ListRasters()
rastersCount = len(rasters)
counter = 0
dek = 1

# compute dekad rasters
while counter < rastersCount:
    dekad = []
    for i in range(counter,(counter+4)):
        print i
        dekad.append(rasters[i])
        outCellStatistics = CellStatistics(dekad, "MEAN", "NODATA")
        outRasterName = out_ws + 'r{:03d}_EVI.tif'.format (dek)
        #outRasterName = "00" + str(dek) + ".tif"
        outCellStatistics.save(outRasterName)
    counter += 4
    dek += 1‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

>>> out_ws = "c:/rasters/"
>>> dek = 1
>>> outRasterName = out_ws + 'r{:03d}_EVI.tif'.format(dek)
>>> outRasterName
'c:/rasters/r001_EVI.tif'

just use forward slashes ... it is the easiest option and totally acceptable

Dan Patterson‌. Thank you very much. I have solved the issue as per your suggestion. i replaced it by forward slashes.

But why the actual copied path is not working? is there any reason

raw formatting or double backslashes or forward slashes...

r'D:\MODIS_SURFACE_RF2012\EVI1'

I am not worried about your actual path. The suggest is to formulate paths that are simple and reproduceable and document externally what is where and what the path is called.
