2. Topics
• News (since Workshop II)
Version 1.1 of HDF Explorer
HDF 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 1.1
SDS image options
• Scalar and vector data image
generation
• Scalar data
– Discrete map
– Continuous map
9. Things to do next
some questions
• HDF-EOS
• HDF4 or 5 based ?
10. Next on HDF Explorer
HDF-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)
