Satisfy More Image Requests Faster
Designed to operate with existing image servers and to leverage the dynamic properties of wavelet-based MrSID® and JPEG 2000 formats, Express Server 6.1 enables you to increase the speed of delivery and range of distribution for your geospatial image data and metadata - without any additional investment in hardware or bandwidth.

Ensure Scalability and Performance Through Mirroring
Mirroring is a feature of Express Server that allows you to keep the catalog and spatial index configuration of multiple Express Servers on a network in sync. Since Express Server includes built-in tools for synchronizing catalog information between Express Servers, you can easily add another Express Server to your server farm for load balancing or as a hot spare.

Make the World Your Data Library
Web Map Service (WMS) support in Express Server means WMS-enabled clients can integrate your Express Server image repositories with WMS-compliant geospatial data stores anywhere in the world. Your imagery plays globally while locally you leverage the fastest raster delivery technology available.

Engage a Wider Range of Users
More users can view your geospatial data because imagery distributed using Express Server is interoperable not only with applications supporting open standards such as OGC's WMS, but also with web browsers, custom web applications and third-party applications such as Google Earth. You can also use the JPIP protocol to stream massive JPEG 2000 images over networks in bandwidth-constrained environments. Express Server delivers imagery to any device over any connection.

Speed up Your Raster Delivery in ESRI Applications
Express Server speeds up image delivery with ESRI ArcIMS, ArcGIS Server and ArcGIS Image Server. For example, by adding the raster image power of Express Server to ArcIMS' exceptional vector and client handling capabilities, you can view your maps up to 25 times faster than with ArcIMS alone. You can also publish Express Server catalogs as layers in ArcGIS Server and ArcGIS Image Server, or connect an ArcMap client directly to Express Server, allowing you to work with datasets hundreds of gigabytes in size right on your desktop.

Maximize the Return on Your Database Investment
Natively serve MrSID and JPEG 2000 imagery stored in a database and save up to 95 percent in storage space. Express Server's support for Oracle Spatial enables you to enlist Oracle databases running LizardTech Spatial Express as Express Server image catalogs.

Leverage Updated Sample Applications
Express Server's sample web applications have been updated and are included with the installation, so you can view or show off your imagery using a number of viewing methods - including JavaScript, Flash, and Ajax - right out of the box. LizardTech's ExpressView Browser Plug-in is a freely downloaded viewer that opens all imagery delivered by Express Server. Customizing the sample applications is an easy way to get started running Express Server.

Deliver the Highest Visual Quality
The wavelet-based MrSID and JPEG 2000 image formats enable high compression of images while retaining high resolution and making labor- and storage-intensive image pyramids unnecessary. The acronym MrSID stands for Multi-resolution Seamless Image Database, a way of storing multiple resolutions of a single image within the image itself. The ISO standard JPEG 2000 format uses a similar technology.

Distribute More Complete Data
Support for geography markup language (GML) in Express Server 6.1 means you can add geospatial metadata to your JPEG 2000 imagery and Express Server will deliver it intact to GIS applications and other viewing and programming applications. More than just geocoordinates, geospatial metadata enables you to create JPEG 2000 imagery that is "spatially aware."

Deliver a Better User Experience
In panning and zooming, scenes resolve instantly with MrSID, JPEG 2000 and NITF images served by Express Server. That's because only the pixels the user needs are extracted and delivered as users navigate an image.
