I'm writing this code to write the NDVI value and the date where picture was taken into my attribute table, later i'll export to excel. The code is downloading the images with no problem, but when it pass through the raster layer, it retrieves me an error! I don't understand what is going wrong...

import arcpy
import os
import datetime
from arcpy import env
from arcpy.sa import *
NDVI_tempo = 'Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL_PL'
arcpy.env.workspace = 'Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL\\NAL.gdb'
arcpy.SplitByAttributes_analysis("Area_produtiva3", NDVI_tempo, ['ID_TALHAO'])
#Inicio do download das imagens

down = 'Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL_PL'
image_server = 'Y:\\E - IMAGEM SERVER\\IMAGEM_SERVER.gdb\\F01_PLANETLAB'

arcpy.env.workspace = r'Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL_PL'
fcs = arcpy.ListFeatureClasses()

for fc in fcs: 
    arcpy.DownloadRasters_management (image_server, down, "", fc, "CLIPPING", "CONVERT_AS_REQUIRED", "TIFF", "NONE", "", "NO_MAINTAIN_FOLDER")

    rasters = arcpy.ListRasters()
    for tiff in rasters:
            arcpy.MakeRasterLayer_management(tiff, "Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL\\temp_rast1.tif", "", "", "3")
            arcpy.MakeRasterLayer_management(tiff, "Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL\\temp_rast2.tif", "", "", "4")

            arcpy.CopyRaster_management("Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL\\temp_rast1.tif", "copy_rast1", "","", "", "", "", "", "", "", "", "")
            arcpy.CopyRaster_management("Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL\\temp_rast2.tif", "copy_rast2", "","", "", "", "", "", "", "", "", "")

            Property1Result = arcpy.GetRasterProperties_management ("copy_rast1", "MINIMUM")
            Property2Result = arcpy.GetRasterProperties_management ("copy_rast2", "MINIMUM")

            Property1 = Property1Result.getOutput
            Property2 = Property2Result.getOutput

            Correcao1 = Minus ("copy_rast1", "Property1")
            Correcao2 = Minus ("copy_rast2", "Property2")

            Rastdiv1 = Minus ("Correcao2", "Correcao1")
            Rastdiv2 = Plus  ("Correcao2", "Correcao1")

            NDVI_tiff = Divide (Rastdiv1, Rastdiv2)
            Zonaltif = arcpy.ZonalStatistics (fc, ['ID_TALHAO'], NDVI_tiff, "MEAN", "NODATA")
            Zonalper = Times (Zonaltif, 100)
            Zonalint = Int (Zonalper)
            arcpy.RasterToPolygon_conversion (Zonalint, Zonalpoly, "SIMPLIFY", "VALUE")
            arcpy.Intersect_analysis ([Zonalpoly, fc], "Z:\\04 - Temp\\Charles\\NDVI_tempo\\NAL_PL\\teste\\Intertif", "ALL", "", "")
            arcpy.AddField_management (Intertif, Data, "TEXT", "", "", "", "", "", "", "")
            tiff_name = arcpy.Describe(tiff).name
            field_name = "{}".format(tiff_name[5:13])
            field_value = datetime.datetime.strptime('field_value', '%Y%m%d').date()
            arcpy.CalculateField_management (Intertif, Data, field_value, "", "")
            arcpy.Delete_management (tiff, "")

You are using MakeRasterLayer incorrectly. The first parameter is the full path to the dataset on you computer, the second parameter is and I quote from the Help file "The name of the temporary output raster dataset". You have instead provided a full path to a file.

It should be a simple string like "temp_rast1". Then you have created an in memory LAYER called temp_rast1 which is pointing to your raster DATASET on your hard drive.

Your line should look like this:

arcpy.MakeRasterLayer_management(tiff, "temp_rast1", "", "", "3")
  • It keeps showing the same message... It's like it don't recognize the image like a valid input, but i did it before manually and it works
