- This exercise is part of the QGIS Tutorial 2013/14.
In this exercise you will learn how to create images of several bands of satellite data, and how to georeference a raster image.
Multiband layers
To create a multiband image:
- Load the different satellite band layers into QGIS. For exercise purposes, you can use the landsat-bands from the directory geodata/raster/landsat/ in the course data; the layer names start with sub, the band number is indicated by B and a one- or two-digit number, e.g. B1 or B10 for the first band and B1 or B20 for the second.
- If the processing toolbox is not visible in you QGIS window yet, select Processing --> Toolbox.
- In the processing toolbar, type merge into the search field to find the merge tool and open it.
