3-D Data Cube is a graphical tool you can use to view a three-dimensional display of multilayer data, including hyperspectral. By using a 3-D data cube, you can get a sense of the structure of the data you are working with; that is, you can easily assess the number and nature of spectra endmembers present in a scene.
When using hyperspectral data with 3-D Data Cube, you can see the spectral bands where there is high atmospheric absorption and, therefore, very little signal reaching the sensor: black layers. Because hyperspectral data files are typically quite large, you must create a subset if the data is not v-cube compressed. Doing so facilitates faster rendering, rotation, and excavation of the data cube.
While you can use data of any bit depth, 3-D Data Cube is optimized for use with 16-bit data. Compressed and decompressed data, and raw hyperspectral files are supported.
Files must contain a minimum of one image channel that has wavelength information.
You can display, rotate, and excavate 3-D data. The cube is displayed in an arbitrary orientation, with a rectangular cutout, and using parallel projection.
You can work in the view pane while the 3-D display is active.
