Quick Tutorial

This is quick walkthrough tutorial on utilizing the graphical user interface. In this case, we will use it to generate a true-color composite and an NDVI (Normalized Difference Vegetation Index).

1. Firstly, to initiate the graphical user interface, we enter the following command in a console:

rforge

2. With the GUI initialized, we can now proceed.

3. We begin by opening the Layer Import Window.

4. Now, we’ll select a file by clicking the file selector button and choose an appropriate scale. Afterward, we’ll designate the bands to import along with their identifying names. Finally, we initiate the import process by clicking on the import button.

5. All the imported bands are now usable in the Layers panel

6. We can now proceed with the process generation. Firstly, we’ll select the Composite button in the Processes panel. Then, from the dropdown selector, we’ll choose the preset for a true-color composite. Next, we’ll populate the options with the required Layers and click Build. The resulting composite should appear in the viewer on the right-hand side. This result can be freely saved as a Layer for further use or exported as GeoTIFF or PNG.

7. Now, let’s navigate Back from the Composite panel to the main Processes panel. Here, we’ll opt for the Multispectral Index button instead. From the dropdown menu, we have a wide selection of indices to choose from, and for this demonstration, we’ll select the NDVI. Once again, we’ll fill in the options with the necessary Layers and click Build. The resulting output should now display in the viewer on the right-hand side.
