Tiling of a Geospatial raster in R
It often happens that we want to process some raster data faster or simply split it up. For this we need a tool for tiling rasters. Of course we can write such a tool ourselves, but why should we do that, because in the rich repository of R there is surely already such a tool 🙂 With the help of this task, we will have the meteo library and the tiling function at our disposal. This function allows us to create tiles of a certain size and with a buffer. Additionally, the created tiles can be saved directly to a specified folder. You will see how to do this in the new video:
