Get netCDF sample data here - Example netCDF files 

  • Voxel Layer only works for Local Scenes
  • To add a new Voxel Layer Map tab-> Add Data -> Add Multidimensional Voxel Layer
  • Files that work for voxel layer – netCDF will dimensions 3 dimensions and time or netCDF with 2 dimensions and time
  • Auxilliary variables do not work for voxel layer (variables where the dimensions of the voxel is defined using a proxy dimension such as trajectory instead of directly referencing realworld dimensions)
  • To change variables, there are two ways:
    • Go to Appearance tab which only appears when you select Voxel Layer -> go to Variable group
    • Right Click on Layer -> Select Symbology -> Use the Variable dropdown
  • To create isosurfaces and sections, select Section radio button :
    • For isosurfaces -> Right click on Isosurfaces -> Create Isosurface (upto 4).
    • To Edit Isosurface, right click on isosurface -> Edit -> Voxel Exploration pane should open that you can use to edit the value and color of the isosurface
    • For Sections -> Right Click on Sections -> Create Section -> Use the toolbar to create horizontal section with one click and vertical sections with 2 clicks
    • To Edit Section, right click on section -> Edit -> Voxel Exploration pane and the toolbar should open that you can use to edit the position of the section.
    • To lock the section, right click on section -> Lock section. You cannot move or change the variable of a locked section
  • If your variable is time enabled, a time slider will show. Use the time slider to animate over different timestamps
  • Use the popup for more information on specific voxels
