如何使用gdal_translate或gdalwarp将HDF5转换为geotiff？

Question

我可以帮您翻译成中文：

我有一个10度乘以10度的未地理参考的HDF5文件，我想将其转换为geotiff格式。 我尝试了两种方法（1）gdalwarp和（2）gdal_translate，但是无法找到如何转换文件的方法。

1）gdalwarp

gdalwarp -t_srs '+proj=longlat +datum=WGS84 +no_defs ' -te 40 30 50 40 -tr 0.0089285714 -0.0089285714 -multi HDF5:"/PathToTheHDF/FileName.HDF5"://SUBDATASET /PathToOutput/FileName_Subdataset.tif

我有以下错误：

ERROR 1: Unable to compute a transformation between pixel/line
and georeferenced coordinates for ...
There is no affine transformation and no GCPs.
256

2) gdal_translate

gdal_translate -of GTiff -a_srs '+proj=longlat +datum=WGS84 +no_defs ' -a_ullr 40 40 50 30 HDF5:"/PathToTheHDF/FileName.HDF5"://SUBDATASET /PathToOutput/FileName_Subdataset.tif

我遇到了以下错误:

您有任何想法，或者应该如何转换这些数据吗？

Answer 1

gdal_translate your_HDF_file -sds output.tif

使用 -sds 选项将把您的多波段HDF5文件拆分为多个单波段tif文件。

Answer 2

使用R和gdal_translate：

library(gdalUtils)

band <- 1

file_path <- "/myfolder/myfile.hdf"

system(paste0('gdal_translate ', get_subdatasets(file_path)[band],' myfile_', band','.tif'))

Answer 3

试试这个：

gdalwarp your_HDF_file_sds C:\Save\your\file\sample.tif
