I am trying to read a MODIS HDF file with Python. I have used GDAL and pyhdf libraries. However, I am unsure why GDAL is unable to read location coordinates whereas pyhdf can read the same easily.
Following is the simple python code.
```
from pyhdf import SD
from osgeo import gdal
filename = 'MYD04_3K.A2016001.0310.061.2018059005952.hdf'
gdal_ds= gdal.Open(filename)
hdf_ds = SD.SD(filename)
print (hdf_ds.datasets())
for path, desc in file.GetSubDatasets():
print(desc)
```
The output for pyhdf is as follows:
{'Longitude': (('Cell_Along_Swath:mod04', 'Cell_Across_Swath:mod04'), (676, 451), 5, 0), 'Latitude': (('Cell_Along_Swath:mod04', 'Cell_Across_Swath:mod04'), (676, 451), 5, 1), 'Scan_Start_Time': (('Cell_Along_Swath:mod04', 'Cell_Across_Swath:mod04'), (676, 451), 6, 2), 'Solar_Zenith': (('Cell_Along_Swath:mod04', 'Cell_Across_Swath:mod04'),
The output for GDALis as follows:
[676x451] Scan_Start_Time mod04 (64-bit floating-point)
[676x451] Solar_Zenith mod04 (16-bit integer)
[676x451] Solar_Azimuth mod04 (16-bit integer)
I would like to learn why GDAL is unable to read location coordinates here. Is there anything I'm missing? How can I extract the location information by using GDAL library? My main aim eventually is to plot a specific variable from HDF file on map.
