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
1 2 3 4 5
| from osgeo import gdal
ds = gdal.Open('example.tif') ds = gdal.Translate('example.img', ds, format='HFA') ds = None
|
Translate()
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14
| from osgeo import gdal
src_ds = gdal.Open('example.tif')
driver = gdal.GetDriverByName('HFA')
dst_ds = driver.CreateCopy('example.img', src_ds)
dst_ds = None src_ds = None
