MrSID is becoming the most widely accepted raster geospatial compressor/viewer on the market today providing a complete solution for electronic distribution and manipulation of massive imagery, including compression, fast viewing, and high image quality. With a MrSID Compressor, individual images or image sets of practically any size can be compressed with complete geometric and geospatial integrity. Viewing MrSID compress imagery is now a fully integrated feature inside Esri ArcView GIS 3.1.

Gone are the days of shuffling through disks of image tiles or painstakingly panning through huge mosaicked images. MrSID’s patented, seamless image compression feature can automatically mosaic multiple image tiles seamlessly into a single, high-resolution MrSID image that can be panned can zoomed in seconds locally or over the Internet.

Introducing MrSID

MrSID is a revolutionary, wavelet-based image compressor, viewer and file format specifically designed for massive raster images enabling instantaneous viewing and manipulation locally and over networks. Unlike other compression technologies, MrSID produces unprecedented compression ratios while, at the same time, preserving maximum image quality. With a MrSID Compressor, individual images or image sets of practically any size can be compressed with complete geometric and geospatial integrity. MrSID’s patented, seamless image compression feature automatically mosaics multiple image tiles seamlessly into a single, high-resolution MrSID image that can be panned and zoomed in seconds.

The MrSID technology was originally designed at Los Alamos National Laboratory for efficiently storing and retrieving high-quality digital orthophotography. LizardTech acquired the technology and expanded MrSID’s features for commercial applications.

Now, viewing MrSID compressed imagery is a fully integrated feature inside Esri’s ArcView GIS 3.1. LizardTech has developed a fully integrated extension inside ArcView GIS 3.1 for viewing massive, georeferenced images. The MrSID Image Reader extension within ArcView GIS now lets you quickly browse hundreds of megabytes - even gigabytes - of imagery that, until now, have been difficult to handle in traditional GIS software.

MrSID Image Support Extension

In the example below, the original image was comprised of 16 gigabytes of individual TIFF Orthophotos of the county of San Diego. Using MrSID Compress Publisher™, the entire image set was automatically seamed together and compressed into a single 850 Mb .sid file. When opened in ArcView GIS, MrSID’s Selective Multiresolution Browsing™ feature, lets you zoom and pan anywhere in the image almost instantaneously, all the way down to the base image data–in this case 1 foot per pixel.

MrSID files (.sid) work just like other image file formats within ArcView, only faster and with more functionality. To access MrSID imagery within ArcView, simply load the MrSID Image Support extension and open a .sid file using the "add image theme" command. It’s that easy.

MrSID Benefits

• Unsurpassed Compression Ratios

• Uncompromised Image Quality

• Selective Multireolution Browsing

• Selective Decompression

• Seamless Wavelet Compression

• Automatic Seamless Mosaicking

• Compress an Image of Practically Any Size

• Georeference Support

(Caption for .tif:) When you zoom into a MrSID image, the image quality gets better with every click instead of worse, like diving into the actual scene. Because MrSID selctively decompresses only the area of the image you need, massive images can be browsed in seconds. MrSID also maintains geometric accuracy, so it fits easily into your GIS workflow!
