Dear all,
I am now working with GEFED dataset, which is a global wild file dataset.You
can download one from FTP: fuoco.geog.umd.edu; Login name: fire; Password:
burnt; The file is stored into gfed4/monthly/. Any one file will be example.
My task is to translate the hdf file into tif, which can be done by gdalUtils
package. But there is no georeferecing information in the file. Instead, the
only information I could find is from the data manual (can be found in gfed4
folder in that FTP): "Each product file contains seven data layers, each stored
as a separate HDF4 Scientific Data Set (SDS). Units apply to each layer after
multiplying by the specified scale factor. Each data layer has 720 rows and
1440 columns which correspond to the global 0.25◦ GFED grid. The center of the
upper left grid cell is located at longitude 179.875◦W, 89.875◦N.". I think the
original src can be written from this statement. And I can pass it to a_src and
a_ullr variable in gdal_translate command. But I have no idea what is the
string for a_src.
Any recommendation will be appreciated.
