从HDF转换为GeoTiff

11

从HDF转换为GeoTiff时遇到一些问题。

我正在按照此网页中描述的步骤进行操作。问题是我无法找到NDVI子数据集名称（XXXX）来运行gdaltranslate命令。

gdal_translate -of GTiff HDF4_EOS:EOS_GRID:"MOD13C2.A2001001.005.2007078152825.hdf"
 :MOD_Grid_monthly_CMG_VI:XXXX modis_ndvi01.tif

这是文件（MOD13C2.A2001001.005.2007078152825.hdf）之一的gdalinfo输出：

如果您尝试输入全名“ HDF4_EOS：EOS_GRID：“ MOD13C2.A2001001.005.2007078152825.hdf”：MOD_Grid_monthly_CMG_VI：CMG 0.05 Deg Monthly NDVI，该怎么办？

不用担心，赛勒斯，我仍然不确定它是否有效。我喜欢您的答案，也对此表示赞同。因此，请不要删除它。:)

谢谢你们！并非完全按照您的建议工作，但是已经接近了： gdal_translate -of GTiff HDF4_EOS：EOS_GRID：“ MOD13C2.A2001001.005.2007078152825.hdf”：MOD_Grid_monthly_CMG_VI：“ CMG 0.05 Deg Monthly NDVI” ndvi.tiff

@AR我再次查看了您在问题中发布的链接，并注意到其中提到了FWTools。我测试了Chethan和我在Ubuntu上建议的方法，它可以正常工作，但是我没有在Windows上使用FWTools测试它。也许使用FWTools解析输入名称有些不同？无论如何，我很高兴您找到了解决方案。有时我会在工作中使用FWTools，所以我相信迟早会再参考您的回答。谢谢。

我想你差不多了。确保在整个输入名称周围加上单引号，在hdf文件名称周围加上双引号。

gdal_translate -of GTiff 'HDF4_EOS:EOS_GRID:"MOD13C2.A2001001.005.2007078152825.hdf":MOD_Grid_monthly_CMG_VI:CMG 0.05 Deg Monthly NDVI'

希望能有所帮助
