There are some small rasters that might be suitable for testing here. These are simulated but georeferenced - we could pick one (say 1127.tiff) and if it's small enough we can provide it in the package. We might also be able to make a suitable dataset using the raster function, just like the raster package does. We could also make a small one from remap, such as the Gulf of Carpentaria mangroves.
