这可能看起来微不足道,但我似乎可以跟踪错误,而且我对 Python 非常陌生,尽管对编程不熟悉。通过在互联网上阅读了一下,我认为我的问题是 .dat ENVI 图像文件没有被读取为“描述对象”。但是我怎样才能让它被这样阅读呢?我可能也需要它来读取标题信息,有什么解决方案吗?

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

好的,所以我实际上自己想通了。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')
