HDF Explorer: Data Visualization and Management Software

HDF Explorer is a powerful software that allows users to read, manage, and visualize HDF and HDF-EOS data. With a user-friendly interface and various image generation options, it provides efficient data browsing and analysis capabilities for large datasets. This workshop will cover the latest version of HDF Explorer as well as its integration with HDF-EOS data, including geolocation, point, swath, and grid data types. Join us to learn more about this essential tool for space research data analysis.

  1. HDF Explorer ByPedro VicenteSpace Research,Inc HDF-EOS WORKSHOP IV September 19, 20 & 21 2000 Landover, MD www.space-research.pt

  2. Topics • News (since Workshop II) Version 1.1 of HDF ExplorerHDF Inspector version 1.0 • Things to do next

  3. HDF Explorer • What is HDF Explorer ? • HDF data reader and visualization • Data in a tree browsable window • Data loading of each item on user request • Several options on image generation (SDS) • Platform: Microsoft Windows

  4. HDF Explorer 1.1 • Reads HDF5 • Better data management for large datasets • What is HDF Inspector ? • Free downloadable program, shows SDS (datasets) as numeric data (grid)

  5. HDF Explorer 1.1SDS image options • Scalar and vector data image generation • Scalar data • Discrete map • Continuous map

  6. SDS discrete map • Different grid cell size supported

  7. SDS vector map (velocity field) • Combine 2 datasets (vector components)

  8. HDF Explorer 1.1 • Demo

  9. Things to do nextsome questions • HDF-EOS • HDF4 or 5 based ?

  10. Next on HDF ExplorerHDF-EOS • Visualizing HDF-EOS data: not as direct as “normal” HDF data • HDF data: numeric arrays , images, text.

  11. HDF-EOS visualization items Point data; we have geolocation, how do we get the underlying map information ? Possible solutions: provide user input to choose this kind of data, combine with other data (grid)

  12. HDF-EOS visualization items • Swath data • Combine all the different types of information (geolocation fields, dimensions, dimension maps and data fields ).How to show this information ?

  13. HDF-EOS visualization items • Grid data • Generate the projection(s)
