RasterFrames brings together Earth-observation (EO) data access, cloud computing, and DataFrame-based data science. It provides a DataFrame-centric view over arbitrary raster data in a horizontally scalable compute environment, enabling spatiotemporal queries, map algebra raster operations, and compatibility with the ecosystem of Spark ML algorithms. By using the DataFrame as a unified cognitive and compute model, RasterFrames makes the rapidly growing EO data footprint accessible to general analysts and EO specialists in a form that scales from the laptop to the supercomputer.
