R&D
− High performance− Simple concurrency /
distribution− Near real-time response− Elastic− Resilient− Compose models (op chaining)− Play well with others
Objectives
− New raster file (ARG)− Raster functions
−Local−Neighborhood (simple)−Zonal
− Integer and float support− Some vector− Tiling (large rasters)− Fast performance− Benchmarking suite
