In most cases, rasters are supplied in tiles; if there are lot of them, this means that you need to think about how you are going to manage them. Sometimes, the best practical measure to do this is to merge the rasters together into a single file. This can present some complications, normally in terms of the size of the merged raster output.
In a new QGIS project, load in the raster layers SU55SW, SU55SE, SU55NW, and SU55NE from the repository for this chapter, the link of which is in the Preface. Then, follow these steps:
- Go to Raster | Miscellaneous | Merge:
- In the Merge window, choose the files that you want to merge from the Input layers browser button (SU55SW, SU55SE, SU55NW, and SU55NE).
- Check the Grab pseudocolor table from first layer option. This will make sure that the right color bands are applied across all of the merged files. Keep all...
