• Array stores for cubes and models Chunked arrays for gridded products, model output and imagery.
• Spatial databases SQL with spatial types, indexes and functions for vector and asset data.
• Tiered storage and retention Hot, warm and cold tiers with retention schedules by product and contract.
• Long-term preservation Archives that keep data, metadata and representation information usable for decades.
