How to resolve : "IndexError: band index 1 out of range (not in ())". Raster. Rasterio

Question

我正在尝试绘制 MODIS 数据产品 MOD09GQ。以下是我的代码和控制台输出：

import rasterio
from rasterio.plot import show
import numpy as np
import matplotlib.pyplot as plt

filepath1 = '/Users/sayantanmandal/Projects/MODIS/MOD09GQ.A2010200.h26v06.061.2021166023144.hdf'
with rasterio.open(filepath1) as modis:
    print(modis.profile)
    print(modis.crs)
    show(modis)

控制台输出：

{'driver': 'HDF4', 'dtype': 'float_', 'nodata': None, 'width': 512, 'height': 512, 'count': 0, 'crs': None, 'transform': Affine(1.0, 0.0, 0.0,
       0.0, 1.0, 0.0), 'tiled': False}
None

During handling of the above exception, another exception occurred:

rasterio/_io.pyx in rasterio._io.DatasetReaderBase.read()

IndexError: band index 1 out of range (not in ())

一开始我以为可能是图像对所选区域没有任何值。但是当我在 QGIS 中打开这个文件时，我确实得到了一张多波段图像。我可能在假设一些事情上是错误的，并且可能会抛出错误的行话，因为这个主题对我来说非常新。知道可能导致此错误的原因是什么吗？谢谢

Answer 1

我不知道你说的数据。

你的数据有多少波段？如果您查看配置文件结果，结果为 0。
（如果只有一个波段，它应该产生 1。）

您可能唯一的问题是您的数据是否组织成 rasterio 理解的数组。

Rasterio 理解（波段、高度、宽度）。

检查这是什么print(modis.read().shape)

如果出来的不一样，用numpy改一下，让rasterio能看懂。

Answer 2

已解决此问题。

import rioxarray as rxr

modis = rxr.open_rasterio('/Users/sayantanmandal/Projects/MODIS/MOD09GQ. 
        A2010200.h26v06.061.2021166023144.hdf', masked = True)

type(modis)

控制台输出：

xarray.core.dataset.Dataset
