In this chapter, we will continue with the material presented in Chapter 4, Working with Rasters, moving on to more advanced operations. These involve either the modification of the geometric properties of a raster or direction- and distance-related calculations on rasters; mostly using additional functions in the raster package. Examples related to the analysis of spatio-temporal remote sensing data will be presented in the last section of this chapter, to demonstrate how more complex, custom-made procedures of raster processing can be constructed.
In this chapter, we will use objects that we previously created in Chapter 3, Working with Tables, and Chapter 4, Working with Rasters.
In this chapter, we'll cover the following topics:
Modifying the geometry of raster layers
Applying focal filters
Clumping patches of connected cells
Resampling and reprojection of rasters
Performing topography-related calculations on elevation data
Aggregating...
