Question

这看似微不足道，但我似乎可以跟踪错误，我对Python非常新，但不是编程。从在互联网上阅读一下，我认为我的问题是.dat ENVI图像文件没有被读作“描述对象”。但我怎么能这样读呢？我可能还需要它来阅读标题信息，任何解决方案？

这是我的代码：

import arcpy #make sure you run the python associated with ArcGIS
import os

filepath = 'filepath'
filename = 'filename'
band_names = range(1,225)

# Path creation
in_folder = filepath + os.sep + 'ENVI'
out_folder = filepath + os.sep + 'GeoTIFF' # preferably an empty folder

# input multiband raster
in_ENVI = in_folder + filename '.dat'
in_raster = raster(in_ENVI)
index = 0

# get raster information specific to each band
desc = arcpy.Describe(in_raster)

################### THIS IS WHERE I GET THE ERROR ##################
Runtime error 
Traceback (most recent call last):
  File "<string>", line 23, in <module>
NameError: name 'raster' is not defined
################### SCRIPT TERMINATED ##############################

for band in desc.children:
    print band
    bandName = band.name
    band_path = os.path.join(in_raster, bandName)
    dest_path = os.path.join(out_folder, filename '_' + band_names(index) + '.tif')
    arcpy.CopyRaster_management(band_path, dest_path, "", "", "", "NONE", "NONE", "")
    index = index + 1

Answer 1

好的，我实际上是自己想出来的。这是我使用的代码。该错误实际上不在arcpy.Describe（）中，而是在arcpy.CopyRaster_management中，因为我没有将band_name [index]转换为字符串。

dest_path = os.path.join(out_folder, filename + str(band_names[index]) + '.tif')

Python Arcpy.describe阅读ENVI.dat时遇到问题
