#DEFINE RASTER SERIES#

Since the raster is regular (i.e., its rows and columns are parallel to the axes, and step size in the x and y direction is fixed), there is no need to actually store all coordinate values: just four numbers are sufficient to calculate them. The purpose of the first three is to convey the coordinates of all raster pixels. Let us now clarify the spatial property terms listed above: extent, origin, resolution, and CRS. 12.2 Inverse Distance Weighted interpolation.11.3 Aggregation of spatio-temporal rasters.

10.7.5 Extracting to polygons: multi-band.

10.7.4 Extracting to polygons: single-band.

10.7.3 Extracting to points: multi-band.

10.7.2 Extracting to points: single-band.

8 Geometric operations with vector layers.

You can do this by providing the new projection as a single argument in which case the function sets the extent and resolution of the new object.

6.6 Generalizing raster algebra with st_apply Project the values of a Raster object to a new Raster object with another projection (coordinate reference system, (CRS)).

6.4.3 True color and false color images.

6.4.1 Arithmetic and logical operations on layers.

6.2.1 Selecting rows, column and layers.

5.3.7 Visualization with plot, mapview and cubeview.

4.4.3 Example: the rainfall.csv dataset.

3.3.2 Function definition vs. function call.
