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.

History of MrSID

• Originally developed at Los Alamos National
  Laboratory.
• Years of research development behind the
  technology.
• Same team developed wavelet-based image standard
  used by FBI.
• Three patents issued.
• LizardTech established as exclusive
  commercialization agent through U.S. Technology
  Transfer Act.
• LizardTech developed commercial MrSID
  application.
• First commercial product introduced in March 1997.

7
MrSID Commercialization

• LizardTech responsible for standardization and
  extension of technology.
• Broad-based industry and user support.
• Initial market focus includes Mapping/GIS,
  Document Management, and Medical Imaging.
• Goal Make MrSID a standard like Microsoft Word
  , Adobe PhotoShop ,and ArcView GIS .

MrSID Benefits

• Next-generation, wavelet-based image compression.
• Inherent Multiresolution.
• Seamless, automatic mosaicking during
  compression.
• Image Database innovation which allows selective
  decompression of any part of the image.
• Ideal for massive images (100s of Mb/Gb).
• High compression ratio variable settings.
• One file format, any platform/OS.
• Highest quality in the market.

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).

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.
