  1. HDF Explorer By Pedro Vicente Mind HDF-EOS WORKSHOP II September 22, 23 & 24, 1998 Landover, MD

  2. Topics • Why we adopted the HDF data format • The HDF Explorer ancestor:A graphical interface for an hydrodynamic numerical model • HDF Explorer

  3. Why HDF ? • (We )Marine Environment unit at Technical University of Lisbon (Portugal) MARETEC (1993-1997) • http://hidrox.ist.utl.pt/maretec

  4. 3D baroclinic hydrodinamical and transport model • Since 1984. FORTRAN coded • Initial system: VAX/Open VMS: data is written in binary format • Later: VAX/ Open VMS with different word size: result: convert all the data • Later again: (1993)Digital Alpha/NT result: convert all the data

  5. 3D baroclinic hydrodinamical and transport model • Later again: Intel Pentium/NT result: convert all the data • Enough: Let´s go to HDF: main advantages: portability, graphic tools that read it.

  6. The HDF Explorer ancestor:A graphical interface for the model • Why do it ? 2 reasons: • The model has very specific features (sigma/ double sigma coordinate system) • The lack of a definite Windows based graphical software

  7. Examples: model grids

  8. Examples: density fields (2d maps)

  9. Examples: velocity fields, contours

  10. HDF Explorer • (We )MIND (1997-1998) • Multimedia and Industrial software . Headquarters : Lisbon (Portugal) • http://www.mind.pt/hdf.explorer

  11. The Future • HDF-EOS • 3D (Open GL) • Contours • More: feedback from customers

  12. Cellular automata in 3D Space simulation including cellular automata, hydrodynamics and eulerian dispersion with http://hidrox.ist.utl.pt/maretec/vicente/software/spacewin/spacewin.htm
