Image Cube
The Image Cube tool visualizes a raster image in an interactive 3D view:
Select the raster image.
Specify the:
- Top Plane renderer. It can be any raster renderer known from QIGS, e.g. a Multiband
color renderer that shows the true color bands
Cube & Slice renderer. This must be a render that uses a single band only, e.g. a Singleband grey or Pseudocolor renderer. It will colorize the band-related pixel values of the 3D image cube and planes relating to the X, Y or Z slice.
Press Load Data to (re)load and render the raster image values.
The 3D scene contains the following elements:
Top Plane - a raster layer for spatial orientation
Image Cube - a volumetric representation of the raster image, showing the raster bands on the z axis
X Slice - a slice along the raster’s X / column / sample dimension
Y Slice - a slice along the raster’s Y / row / line dimension
Z Slice - a slice along the raster’s Z / band dimension
Box (Image) - a 3D bounding box along the maximum image extent
Box (Subset) - a 3D bounding box to show the extent of the spatial subset that migh be used to focus on specific image areas

Reclassify
The Reclassify tool is a convenient graphical user interface for reclassifying classification rasters.
Specify the file you want to reclassify under Input File. Either use the dropdown menu to select one of the layers which are already loaded or use the button to open the file selection dialog.
Under Output Classification you can specify the classification scheme of the output classification which will be created.
You can import schemes from existing rasters or text files by clicking the button.
To remove entries select the respective rows and click the button.
So save a classification scheme select the desired classes (or use Crtl + A to select all) and click on the button.
Likewise, you can copy and paste classes by selecting them and clicking the Copy Classes Paste Classes buttons.
The table is sorted by the Label field in ascending order. The value in Label will become the pixel value of this class and can not be altered.
Double-click into the Name field in order to edit the class name.
Double-click into the Color field to pick a color.
Under Class Mapping you can reassign the old classes (From) to values of the new classification scheme (To)
Specify the output path for the reclassified image under Output File
Click OK to run the tool.
Scatter Plot
The Scatter Plot allows to plot two raster bands, or a raster band and a vector field against each other. The visualization of both, denstity and scatter is supported.
Plotting Raster Band vs. Raster Band
When plotting raster data against each other, we usually want to display the bin counts as colorized density.
- Usage
Start the tool from the Tools > Scatter Plot menu or from the layer context menu inside the Data Views panel.
Select two raster layer bands used for x and y values.
Select Density option for Coloring and choose a color ramp.
