storing geo-referencing info in HDF5 format

Please let me know whether geo-referenced image data can be written in
HDF5 format retaining the info

Sita,

You may need to elaborate more for your question.
In short, It is possible to store geo-referencing info in HDF5 since HDF5 is a general data format that allows you to store metadata in object attributes. You can store the info. like lat/lon in HDF5 datasets. However, to make the applications understand the geo-referencing info, you may need to follow the HDF-EOS or netCDF-4 data model to create your HDF5 files.

You can create an image by following the HDF5 image specification. However, the image is not geo-referenced.

Sita,

I would suggest to use netCDF-4 HDF5, see http://www.unidata.ucar.edu/software/netcdf/docs/user_guide.html
If you have to stick to HDF5, you can use the dimension scale API, see https://www.hdfgroup.org/HDF5/doc/HL/RM_H5DS.html

Furthermore, I would suggest to use the CF conventions and metadata to implement geo-referencing in HDF5/netCDF-4 files, see http://cfconventions.org/

Good luck, Richard
