MrSID Benefits
|
Alternatives
|
|
High Compression Ratios
|
- Reduce file size as much as 100:1, avg 20-50:1
- Reduced storage requirements
- Faster transmission
- Instantaneous viewing/browsing
- Saves time, saves money
- Saves disk space, saves money
|
- JPEG cannot compress higher than~15:1 without significant image degradation.
- FlashPix cannot compress higher than~15:1
- Other Wavelet Compressors cannot offer quality or user features.
|
|
Superior Image Quality
|
- Maintain superior image quality with high compression ratios.
- Maintains complete geometric and geospatial accuracy.
|
- Poor quality at high compression ratios. JPEG generates unacceptable blocking artifacts.
|
|
Multiresolution
|
- Generates many resolutions in a single file.
- When you zoom, image quality gets better with each click instead of worse.
- Compressed, multiresolution files at least ~30% smaller than those of competition.
- Compressed, multiresolution files are faster than those of competition.
|
- FlashPix only provide 5 resolutions and they are not true but rather interpolated. Also, FlashPix resolutions are pre-rendered as separate images stored together with original in a pyramid. Results in larger and slower compressed image.
|
|
Selective Decompression
|
- Instantaneous viewing of massive images locally and over networks
- Only decompress the portion of the image user requests.
|
- No competition. MrSID Selective Decompression is a patented process.
|
|
Seamless Compress/Browsing
|
- Automatically mosaic 100’s of separate images into single image without seams. Pan and zoom around a single high resolution image instead of shuffling many small images. Size is no longer a constraint.
|
- No competition. MrSID Seamless Wavelet Compression is a patented process.
- Other wavelet compressors are not seamless.
|
|
Compress an Image of Virtually Any Size.
|
- The only limitation to the size of image you can compress is the limitations of your operating system. The largest single image compressed with MrSID to date is 37 Gigabytes. This image is viewed in seconds over the internet.
|
- No competition. JPEG is confined to a practical image size of ~50Mb. FlashPix maximum limit is ~150 Mb.
|
|
Extensibility
|
- MrSID Compressors and Viewers run on most platforms and operating systems including Windows 95/NT, Solaris, AIX, IRIX & Mac OS. See our website for current status.
- Runs on consumer level systems
- Fully integrated inside ESRI ArcView GIS 3.1
- Plug-ins available for Photoshop, Netscape, Microsoft Explorer.
- Future integration with Intergraph, ERDAS Imagine, MapInfo Pro/Business Map, Autodesk AutoCAD Map, Bentley Microstation

The increasing use of graphic-intense files in today's business world has created
critical access, storage, and Internet transmission problems at the desktop.
Traditional compression tools are losing ground in the battle to keep files
small, while maintaining maximum image quality and allowing quick downloads.
MrSID from LizardTech breaks through the barriers to fast, high-quality digital
graphics compression, viewing, and manipulation - giving companies the first
truly high-powered compression tool for geospatial raster imagery.
