World’s Fastest Image Serving Technology
- 1. World’s Fastest Image Serving Technology ERDAS APOLLO ESSENTIALS Siya Ngcobo, Application Engineer 21, July, 2015
- 2. Confidential2 Current Market Trends • Managing geospatial imagery remains problematic. Despite cheaper storage and increasing processing power, imagery is continually captured • At higher resolution and bit depth • Over larger coverage areas • More frequently • With more spectral bands • IT Departments have not maintained the velocity of Geospatial Imagery in increasing storage allocations • Storage is still a constraint • End users now demand like never before • Fast end-to-end delivery of imagery. Time is critical • Direct access to historical imagery • Web service delivery • Everything has to be fast.
- 3. Confidential3 WHAT WE DO BEST Help organizations Reduce file sizes of data to cut storage overheads, accelerate data delivery, and boost display performance
- 4. Confidential4 Big Data made Small The World’s Largest Geospatial Image? A single aerial image covering Germany @ 20cm GSD 3,210,000 px by 4,340,000px iBig Data Made Small g Data Made Small 38 TB Uncompressed 370,000 source files 50 TB with image pyramids 875gb ECW Compressed 1 ECW file VISUALLY LOSSLESS
- 5. Confidential5 Compression to ECW ECW image compression: • Instant storage savings • Faster performance • Full visual quality 1000 Gb 400 Gb 50Gb 1300 Gb Uncompressed Original Numerically Lossless Compression ECW Visually Lossless Compression Uncompressed Original & Pyramids

- 7. Confidential7 Storage Costs - Tile-cache & Pyramid vs. ECW Amazon S3 Cloud storage Costs comparison example mazonS3 Cloud storage Costs comparison example • 98% lower costs using ECW • >$4.6k monthly saving • Up to $73k annual saving $ cost per month $ 4,700 ECW $ 82 $ 6,200 Data generated using the Amazon S3 Cloud Calculator $ 4,600
- 8. Confidential8 Single ECW Image Mosaic – South Africa (50cm) • Input Data -------------- • Structure: • 4Band, RGB • 45,816 image files • 29 TB uncompressed • Output Data -------------- • File Type: ECW • Structure: • 3 Band, RGB • Single Image File • 440 GB compressed .
- 9. Confidential9 Hexagon Point Cloud (HPC) format for streaming point clouds Unlock your LiDAR data. Extend the reach of large repositories of LiDAR data stored in the enterprise.
- 10. Confidential10 Worked Example : Streaming • ECW enables • 635mb to 38mb • No visual loss in image quality • Compress in 26 seconds • Decompress faster than original Original 15:1 ECW
- 11. Confidential11 What is ECWP? • Streaming protocol for Lidar and Imagery • Distributed decompression • Client decodes • Client transforms, reprojects • Client caches • US Patents • #US6633688 • APOLLO Server dependency • Efficient Network usage • ECW , HPC and JP2 format compatible • Reduces latency, improves draw performance • Higher performance, less data required than ISO JPIP
