LizardTech® Express Server® software is the fastest, most stable, and easiest way to distribute compressed, high-resolution raster imagery via standard protocols. With Express Server, users on any device access imagery faster, even in bandwidth-starved environments. Support for MrSID®, JPEG 2000, NITF and Geospatial PDF formats ensures the highest visual quality regardless of connection speed.

 
 

Overview


|

Introducing Version 8:

With the new graphical user interface (GUI) for Express Server our customers can easily and quickly configure their Express Server software and their image catalogs from anywhere on the Web without having to open a command line or edit XML files. Now you can set Express Server’s basic properties, configure catalogs, create catalog groups – even license your installation – all in the new GUI, just by logging in with a browser, checking a few boxes, filling in a few fields, and clicking a button or two. We call it the Express Server Manager.

Did you know that many organizations are using PDFs for distributing maps? They’re called Geospatial PDFs and they’re georeferenced files, just like your MrSID and JPEG 2000 files. Well, Express Server 8 supports Geospatial PDF as a source image format, which means you can take advantage of PDF data and serve a wider range of users.

Taking Express Server for a 30-day test-drive is also easier than ever before – download and install it once; if and when you purchase that same installation becomes permanently licensed.


Support for MrSID Generation 4 (MG4):

MrSID Generation 4 (MG4™) is the latest version of the LizardTech® MrSID file format.

MG4 meets the demands of new technologies for analyzing the earth by supporting multi- and hyperspectral imagery and alpha band transparency. Support for MG4 in Express Server means better looking mosaics and greater control over the multi- and hyperspectral imagery you serve.

For more information on MG4, please visit our GeoExpress product page.


With Express Server 8 you can:

  • Quickly and easily distribute high resolution raster imagery
  • Retain high visual quality, regardless of connection speed, with support for MrSID, JPEG 2000, NITF and Geospatial PDF formats
  • Distribute up to 255 bands in MrSID format with support for hyperspectral imagery
  • Run Express Server on a 64-bit operating system to take advantage of memory-based performance improvements
  • Try it for free today. A 30-day trial is available here.


Features and Benefits

FAST

  • Wavelet based MrSID and JPEG 2000 image formats ensure high speed delivery so users have access to more imagery faster.

STABLE

  • Express Server can support all your end users without delays caused by simultaneous requests.

 EASY

  • Enjoy hassle-free installation and configuration without command lines. Express Server installs in minutes and is easy to administer.

STANDARDS-BASED

  • Rest easy knowing your imagery and workflow are secure. Express Server supports industry and ISO standard image formats (MrSID, JPEG 2000, NITF, Geospatial PDF) and integrates imagery from any WMS-enabled GIS anywhere.

Get Started Faster, Administer with Ease

Express Server 8’s graphical user interface makes configuring the software and managing your image catalogs easier than ever before. No more editing XML files or learning command lines; Express Server installs in minutes, and with a few clicks you can be viewing your own imagery in the included sample web applications.

Take Advantage of Innovations in Imaging

Multispectral and hyperspectral imagery are becoming increasingly more integral to the workflows of the geospatial professionals you serve. Express Server supports MrSID Generation 4 (MG4), the latest version of LizardTech’s MrSID format, which enables you to serve out specified bands from multi- and hyperspectral imagery. MG4 also uses alpha-band transparency for better looking mosaics.

Satisfy More Image Requests Faster

Express Server operates with existing image servers to leverage the dynamic properties of wavelet-based image compression formats, enabling you to speed up delivery of your geospatial imagery without having to add bandwidth or hardware. Express Server 8 software supports industry and ISO standard image formats such as MrSID, JPEG 2000, NITF and Geospatial PDF, and runs on standard protocols such as WMS and JPIP. Express Server software runs on 64-bit operating systems, so you can take advantage of memory-based performance improvements.

Deliver the Highest Visual Quality

The advanced wavelet algorithms at the heart of MrSID and JPEG 2000 compression naturally result in multiple resolution levels that are stored within the encoded image file. This “wavelet advantage” enables high compression of imagery while retaining ultra-high quality – lossless quality when you need it – and making labor- and storage-intensive image pyramids unnecessary. Wavelets also enable selective decompression – decoding only the pixels for a requested scene – ensuring both high image quality and rapid delivery.

Engage a Wider Range of Users

Express Server delivers imagery to any device over any connection. Express Server image repositories can be integrated with geographically distributed data stores via many different applications, which means more users can view your geospatial data. 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 images over networks in bandwidth-constrained environments. Express Server also speeds up image delivery with ArcGIS Server and ArcGIS Image Server. Users can view image layers published in Express Server simultaneously with data from server applications or connect an ArcMap client directly to Express Server and work with datasets hundreds of gigabytes in size right on their desktops.

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. Using WMS you can publish your images in a variety of coordinate reference systems and let Express Server mosaic and reproject them on the fly, so your users can work with imagery however they need to. Your imagery is accessible to worldwide users while locally you leverage the fastest raster delivery technology available.

Leverage 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 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.

Ensure Scalability and Performance

Express Server software includes built-in tools for synchronizing catalog information between Express Servers, so you can easily add another Express Server to your server farm for load balancing or as a hot spare.

Distribute More Complete Data

Support for geography markup language (GML) in Express Server 8 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.”

Publish Directly from GeoExpress

Using the Express Server management tools included with versions 7 and later of the GeoExpress® application, you can rapidly export images in MrSID and JPEG 2000 formats to Express Server catalogs without having to reencode them.
