多图像处理（子数据集）

分层数据格式是多个不同数据集的容器。用于数据存储。HDF包含由数据填充的多维数组。一个HDF文件可以包含多个数组。它们在尺寸、尺寸上可能不同。

第一步是使用 gdalinfo ，然后使用gdal_translate导入所需的图像。这个 gdalinfo 实用程序列出输入HDF文件中的所有多维子数据集。单个图像（子数据集）的名称被分配给 SUBDATASET_n_NAME 元数据项。每个图像的描述在 SUBDATASET_n_DESC 元数据项。对于HDF5图像，子数据集名称的格式如下：

HDF5:file_name:subdataset

在哪里？
file_name 是输入文件的名称，并且
子数据集 要使用的数组的数据集名称（用于GDAL中的内部使用）。

在第二步中，您应该为 gdalinfo 或 gdal_translate 用于实际读取数据。

例如，我们希望从OMI/Aura Ozone（O3）数据集读取数据：

$ gdalinfo OMI-Aura_L2-OMTO3_2005m0326t2307-o03709_v002-2005m0428t201311.he5

请注意，您应该在 GDAL 中准确地提供标记行的内容 SUBDATASET_n_NAME ，包括 HDF5型： 前缀。

此驱动程序仅用于以栅格图像（二维或三维阵列）的形式导入遥感和地理空间数据集。如果您想浏览包含在HDF文件中的所有数据，您应该使用其他工具（您可以使用本页末尾的链接找到有关不同HDF工具的信息）。

地理参考

在HDF文件中存储地理参照没有通用的方法。然而，有些产品类型有保存地理参照的机制，其中一些是由GDAL支持的。当前支持的是( subdataset_type 显示在括号中）：

  • HDF5 OMI/Aura臭氧（O3）总柱1-轨道L2条带13x24km( Level-2 OMTO3 ）

多文件支持

从GDAL 3.1开始，驱动程序支持使用“family”HDF5文件驱动程序打开拆分到多个文件的数据集。为此，必须为GDAL提供第一部分的文件名，其中包含单个“0”（零）字符，或以0.h5或0.hdf5结尾

多维API支持

3.1 新版功能.

HDF5驱动程序支持 多维栅格数据模型 用于读取操作。
