- 5. Grid View • An Excel like grid with each cell an element datum 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 5
- 6. Discrete Map View • Data is visualized as a map of colors. The colors are associated with a discrete range of values. 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 6
- 7. Map options • In the Draw options dialog box the user can choose to draw the color of each cell and to draw a grid surrounding each cell. 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 7
- 8. Map options • Now the grid is drawn 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 8
- 9. Fill options • Ignore or not a fill value in the making of the map, that is, the fill value is not translated to a color. The user also has an option to draw the fill value border in the grid. 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 9
- 10. Fill options • A map with the fill values not translated to a color 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 10
- 11. Dimension options • Choose to visualize or not the dataset dimensions (values in legend) in the map 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 11
- 12. Axis options • Options to draw space dimensions information (north, south, east, west, distance between ticks) 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 12
- 13. Size options • Change the size of the image 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 13
- 14. Legend options • Change the values of the legend discrete intervals 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 14
- 15. HDF5 Dimension scales (H5DS) • Allows choosing of one of several Dimension Scales datasets to be shown either in grid or map view 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 15
- 16. HDF5 Dimension scales • Click over each one of the dimension scales to select it. All available dimension scales are shown for each dimension 02/18/14 HDF and HDF-EOS Workshop XI, Landover, MD 16
