I am trying to convert MODIS Leaf Area Index (LAI) data from .hdf to GeoTiff from 2001.

I can successfully convert it using R for the more recent datasets using the following code:

sds <- get_subdatasets("GLASS01B01.V03.A2014001.2016025.hdf")
gdal_translate(sds[1], dst_dataset = "GLASS01B01.V03.A2014001.2016025.tif")

Datasets from 2014 are available here: ftp://ftp.glcf.umd.edu/glcf/GLASS/LAI/MODIS/0.05D/2014/. I am then displaying the output GeoTIFF files in ArcGIS.

However, the result is incorrect for the data from 2001, available here: ftp://ftp.glcf.umd.edu/glcf/GLASS/LAI/MODIS/0.05D/2001/

The spatial extent information seems to be incorrect. The spatial extent is specified within the files as Top: 0.025, Left: -0.05, Right: 0.05, Bottom: -0.025

For datasets from 2014, projected correctly the spatial extent is specified as Top: 90, Left: -180, Right: 180, Bottom: -90.

I have also tried the HEGTool.

Can I correct for this, either in R or in ArcGIS? Maybe some addition to the code will allow me to specify the extent?

In ArcGIS Desktop use the Raster To Other Format for converting from .hdf to .tif.

Here is one example using first file from 2001: ftp://ftp.glcf.umd.edu/glcf/GLASS/LAI/MODIS/0.05D/2001/
