gdal.Translate和gdal.Wrap支持的creationOptions（命令行中的-co参数）
在使用gdal_translate和gdalwarp时，使用-co参数时有时候不知道支持哪些可选项，接下来研究一下：
$ gdal_translate.exe --format GTiff
Format Details:
Short Name: GTiff
Long Name: GeoTIFF
Supports: Raster
Extensions: tif tiff
Mime Type: image/tiff
Help Topic: frmt_gtiff.html
Supports: Subdatasets
Supports: Open() - Open existing dataset.
Supports: Create() - Create writable dataset.
Supports: CreateCopy() - Create dataset by copying another.
Supports: Virtual IO - eg. /vsimem/
Creation Datatypes: Byte UInt16 Int16 UInt32 Int32 Float32 Float64 CInt16 CInt32 CFloat32 CFloat64

其中TranslateOptions和WarpOptions中的creationOptions参数，用法如下：
gdal.Warp(out_tif,
mem_ds,
options=gdal.WarpOptions(
creationOptions=["TILED=YES", "COMPRESS=LZW"],
srcSRS='EPSG:3857',
dstSRS='EPSG:4326'
)
当然，也可用python脚本查询支持的creationOptions参数：
In [1]: from osgeo import gdal
In [2]: driver = gdal.GetDriverByName("GTiff")
In [3]: driver.GetMetadata()
