HDF Explorer

  1. 1. HDF Explorer HDF-EOS WORKSHOP II By Pedro Vicente September 22, 23 & 24, 1998 Landover, MD Mind
  2. 2. Topics • Why we adopted the HDF data format • The HDF Explorer ancestor:A graphical interface for an hydrodynamic numerical model • HDF Explorer
  3. 3. Why HDF ? • (We )Marine Environment unit at Technical University of Lisbon (Portugal) MARETEC (1993-1997) • http://hidrox.ist.utl.pt/maretec
  4. 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. 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. 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. 7. Examples: model grids 10 20 30 40 50 60 70 80 10 20 30 40 50 60 70 80 60 55 50 45 40 35 30 25 20 15 10 5 Mohid Data Explorer Bathyme try
  8. 8. Examples: density fields (2d maps) 10 20 30 40 50 60 70 80 90 60 60 55 55 50 50 45 45 40 40 35 35 30 30 25 25 20 20 15 15 10 10 5 5 10 Mohid Data Explore r 20 30 40 50 60 Temperature (s igma) 70 80 90
  9. 9. Examples: velocity fields, contours 10 20 30 40 35 35 30 30 25 25 20 20 15 15 10 10 5 5 1 0 cm / s 10 Mohid Data Explorer 20 30 Horiz ontal v elocity (s igma) 40
  10. 10. HDF Explorer • (We )MIND (1997-1998) • Multimedia and Industrial software . Headquarters : Lisbon (Portugal) • http://www.mind.pt/hdf.explorer
  11. 11. The Future • HDF-EOS • 3D (Open GL) • Contours • More: feedback from customers
  12. 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
