Raster Tiling

Raster Tiling is a generic preprocessing block that clips rasters into rectangle-shaped tiles and makes them ready for consumption by analytics algorithms. Tiling is especially important for large raster datasets that should be broken up into more manageable pieces to improve performance. Output tiles are GeoTIFFs with the same bands and resolution as the input data. Simple data augmentation is also supported.

General Information	Description
Block Type	Processing (data preparation)
Supported Input Types	AOI Clipped, any georeferenced GeoTIFF
Resolution	identical to the input
Performance	Some ML algorithms can incur errors with tiles if they only support RGB.
