Mastering raster efficiency: how to stack, crop, and mask your GIS maps
In short: This video from the MIT Fall 2023 course on R and Geographical Information Systems teaches essential techniques for managing raster data. You will learn how to organize files more efficiently and refine your visual output by isolating specific areas of interest.
The tutorial focuses on four core operations for handling raster data: stacking, bricking, cropping, and masking. These methods allow users to streamline their workflow when processing complex geographical datasets.
By using stacks and bricks, you can manage multiple raster layers more effectively. The session also covers how to crop maps into smaller, more manageable segments and apply masks to exclude data that is irrelevant to your specific research or presentation goals.
