HTTP -raster,vector- (ro): HTTP Fetching Wrapper使用命令行工具进行栅格格式转换
GDAL库不但提供了C/C++编程语言的API接口，还提供了很多实用的命令行工具，帮助我们完成一些日常的数据处理工作。
我们以将GeoTIFF格式转为IMAGE格式为例，说明如何使用命令行工具进行栅格格式转换：
gdal_translate -of HFA example.tif example.img
其中，of选项指示了输出数据格式，HFA代表的是Erdas Imagine Images ，example.tif是输入数据路径，example.img是输出数据路径
详细参数参考：gdal_translate
使用Python代码进行栅格格式转换
下面介绍两种进行转换的方式：
GDAL 2.1版本之后提供了，从代码中调用命令行的API接口，所以我们可以在Python代码中直接调用
Translate()函数进行转换from osgeo import gdal ds = gdal.Open('example.tif') ds = gdal.Translate('example.img', ds, format='HFA') ds = NoneTranslate()函数的第一个参数是输出数据路径，第二参数是输入数据路径或者输入数据的Dataset对象，后面都是可选参数，具体Translate()函数的参数可以参见：GDAL/OGR Python API使用
CreateCopy()方法进行数据的复制及格式转换from osgeo import gdal # 打开数据文件 src_ds = gdal.Open('example.tif') # 获得数据驱动对象 driver = gdal.GetDriverByName('HFA') # 进行数据格式转换 dst_ds = driver.CreateCopy('example.img', src_ds) # 关闭数据集对象 dst_ds = None src_ds = None
