HDF and HDF-EOS Workshop II (1998)

2. A Unique Opportunity for EOSDIS
The explosion of advanced technology coupled with a more sophisticated, insatiable
demand for information has created a need for accessing big images, real fast.

3. What is MrSID?
• MrSID stands for Multiresolution Seamless
Image Database
• MrSID is a powerful wavelet-based
compressor, viewer and file format for
massive raster images that enables
instantaneous viewing and manipulation
of massive images locally, and over
networks while maintaining maximum
image quality.

4. MrSID Product Description
• MrSID technology includes a full line of
compressors and viewers tailored for different
users.
• MrSID Compress typically compresses 10Mb to 50
Gb images and displays them in seconds.
• Primary benefits include instantaneous browsing
of massive images and increased storage
capacity.

15. MrSID and HDF-EOS
• Use free MrSID Software Development
Toolkit (SDK) to enable existing
applications to read MrSID format.
• LizardTech to accomodate HDF-EOS Grid
format in addition to formats already
supported (GeoTIFF, ERDAS, BSQ, BIP, BIL,
Sun Raster, USGS DOQ, and flat raster).

16. Compression Technology Comparison
Input File: An 8 by 10 inch 24-bit color image scanned at a physical resolution of
300 dots per inch. The image requires 20.6Mb to store uncompressed.

17. Compression Technology Comparison
• MrSID versus Fractal
MrSID has faster decompression
MrSID has superior quality
MrSID has pixel level/geometric accuracy
• MrSID versus FlashPix/JPEG Pyramids
MrSID has much smaller file size
MrSID has better quality & higher compression ratios
MrSID builds views based on existing data (not separate files)

18. MrSID vs JPEG Pyramids

19. Wavelet-Based Competitors
• Other wavelet-based image compression products all
share the same limitations MrSID solves:
• Lack of mission critical image quality.
• Limited size of image that can be compressed.
• Lack of integrated selective decompression.
• Lack of single, cross-platform file format.
• Lack of legacy system support.
• Lack of imaging and mapping industry support.
The ability to compress images of virtually any size without
edge artifacts or seams and Selective Decompression are
the basis for the patented intellectual property in MrSID.
