There are three main utilities provided by terrainr. First, users are able to download data from the National Map via the get tiles function, downloading data tiles for the area represented by an sf or Raster object: Once downloaded, these images are in standard GeoTIFF or PNG formats and can be used as expected with other utilities: Finally, terrainr helps you visualize this data, both natively in R via the new geom spatial rgb geom: As well as with the Unity 3D rendering engine, allowing you to fly or walk through your downloaded data sets in 3D and VR: We can then import these tiles to Unity (following the Import Vignette) to create: The more time intensive processing steps can all be monitored via the progressr package, so you’ll be more confident that your computer is still churning along and not just stalled out. For more information, check out the introductory vignette and the guide to importing your data into Unity!
