This document summarizes a presentation on best practices for creating Earth observation data products that follow the Hierarchical Data Format for Earth Observing System (HDF-EOS) standard. It provides guidance on including geo-location variables, using named dimensions, following Climate and Forecast Metadata conventions, testing products with various tools, and using the HDF Product Designer tool to help design and validate compliant products. The work aims to improve the usability of data products and reduce questions received through help desks.
