Raster images and raw LiDAR files contain an unimaginable amount of geospatial data – requring costly server storage space.
LizardTech’s GeoExpress software compresses massive geospatial images and LiDAR data into high-quality MrSID files that can be opened and viewed immediately. Your 100MB image file becomes a 5MB file with the same high resolution quality. And, the MrSID file type is supported in all geospatial platforms, so there’s no need to spend money on additional formatting software or constant updates.
"The MrSID format provided us an opportunity to speed up the client's use of the imagery and consequently its QC. Equally important, the MrSID format proved more capable of managing its coordinate system information than other formats."
GeoExpress and Compression:
- Raster images are 20 times smaller and visually lossless.
- LiDAR files are at least four times smaller and lossless.
Features and Benefits
Reduce Storage Costs - Compress images to less than five percent of their original size using either the industry-standard MrSID image compression format, or the ISO standard JPEG 2000 format, all while retaining the visual quality of the originals. Alternatively, maintain pixel-for-pixel image fidelity while still reducing image sizes to 50 percent of their original sizes. Not only are compressed images easier to store, they are also perfect for mobile devices and low-bandwidth environments.
Make Images Better - Make existing imagery more visually appealing and more useful with the powerful suite of editing and manipulation tools in GeoExpress. Take advantage of cropping, color balancing, reprojection, and more. Combine multiple images into mosaics, create custom image tiles easily, and export just the sections of imagery that you want at exactly the resolution that you want.
Compress LiDAR Point Clouds - GeoExpress 9.5 now supports LiDAR point clouds stored as ASCII files, LAS files, LAZ files, and MrSID Generation 4 (MG4) files. Reduce the size of your LiDAR files by 75 percent or more while retaining all of your points and all the accuracy of your point data. You can even explore your point clouds in 3-D mode directly from GeoExpress.
Color Balance All Your Imagery - The color balancing tools in GeoExpress aren’t just for mosaics. You can manually or automatically adjust brightness, contrast, gamma and more for one image or for many images. When working with a large numbers of images, you can adjust and preview one image quickly, then apply the same adjustments to all your other images in one fell swoop.
Reproject Imagery - GeoExpress maintains an extensive list of coordinate reference systems so that you can change the projection of your images with just a couple of clicks. Alternatively, you can specify custom coordinate reference systems with Well Known Text (WKT), and you can save time by accessing a list of the coordinate reference systems that you have used recently.
Enjoy Powerful Crop and Export Features - Create images that are exactly the right size and resolution for you. Whether you want to create image tiles with specific dimensions or just extract a particular scene from an image, GeoExpress has all the tools you’ll need. You can select from convenient preset options for web and print, or enter custom dimensions and tiling options. For even more control, you can crop images that match a single polygon or multiple polygon shapefile that you select.
Customize Multispectral Imagery - Compressing multispectral and hyperspectral imagery is a breeze with GeoExpress. You can copy your image bands exactly knowing that MrSID Generation 4 (MG4) images support up to 255 image bands, or you can select any subset of output bands. What’s more, you can change the order of your image bands easily and even set different compression ratios for each band.
Create Seamless Mosaics - Traditionally, enormous images have been slow to open and slow to display, necessitating complex tiling schemes to facilitate interacting with the images. No more. With the MrSID and JPEG 2000 image formats, you can create mosaics of all your images while keeping image sizes low. Moreover, because the formats provide advanced selective decompression functionality, even very large image mosaics remain snappy and responsive.
GeoExpress does more than make mosaics convenient though—it makes mosaics better. Use simple color balancing tools to remove seam lines between images, correct color distortions, and more.
Integrate with Express Server - Export images to the web directly from the GeoExpress interface. GeoExpress integrates with LizardTech’s Express Server software so that you can get your MrSID and JPEG 2000 images to the people who need them as quickly as possible. Out of the box, Express Server includes a full-featured web tool that makes it easier than ever for your users to browse, view, and export imagery straight from their web browsers.
Ensure Interoperability with Geospatial Applications - In the 20 years that the MrSID image format has existed, it has become an industry-standard. You can rest assured knowing that your MrSID imagery is widely supported across the widest range of geospatial applications, including ArcGIS, Autodesk, Intergraph, MapInfo, and Bentley, just to name a few.
Take Advantage of Flexible Licensing - Share image compression and editing tools across your organization. Any version of GeoExpress that you install can be used with floating licenses so that you can maximize value from your organization’s application budget and still increase productivity both in the office and out in the field. Switching between versions of GeoExpress is just as painless. For example, all you have to do to move from the trial version to the standard version is enter another license code and serial number.
Floating Licenses - LizardTech’s optional Floating License System allows you to deploy GeoExpress on workstations throughout your organization with a flexible, token-based licensing system. The “commuter license” now enables you to work offline.

Frequently Asked Questions
What is GeoExpress?
With powerful tools for reprojecting, color balancing, mosaicking, cropping and more, LizardTech® GeoExpress® software is your first choice for manipulating and encoding your geospatial imagery to the industry standard MrSID and ISO standard JPEG 2000 compression formats. GeoExpress supports alpha bands for true transparency control and multi- and hyperspectral imagery for more flexible band utilization. The interoperability within LizardTech’s Express Suite®software means that you can configure Express Server® software directly from GeoExpress, making it the ideal command center for your storage and distribution workflows.
I've heard reference to "MG4," "MG3" and "MG2". What are they?
Those are MrSID format files with the file extension of “.sid.” MG2 stands for MrSID Generation 2, MG3 stands for MrSID Generation 3 and MG4 stands for MrSID Generation 4. GeoExpress can create all three files with MG4 supporting the latest cutting edge technology from LizardTech, such as hyperspectral data, alpha channels and improved mosaicking.
Is GeoExpress backwards compatible with previous versions of MrSID?
Yes. GeoExpress can read all previous versions of MrSID and encode to MG2and MG3 formats. The ExpressView Browser Plug-in utility can view all previous versions of the MrSID file format. ExpressView Browser Plug-in ships on the GeoExpress DVD and is available as a free download at www.lizardtech.com in the downloads section.
I want GeoExpress, but I'm currently using an older version. Can I upgrade or do I have to purchase the entire software?
If you currently are using an older version of GeoExpress, you can still upgrade to the new release. Please contact your LizardTech representative for details and/or any applicable promotional time periods.
What are data cartridges?
Data cartridges are binary encrypted files that enable you to encode images with GeoExpress. Cartridges are not a physical dongle or hardware lock. They are generated by LizardTech based upon your system ID and then emailed to you as an attached file.
Can multiple users in my organization run GeoExpress?
Yes. GeoExpress includes a network version of the cartridge manager on the product software media. Contact your LizardTech sales representative for purchasing additional encoders that can read from the network cartridge manager. If your workflow requires many people in your organization to share encoding tasks, consider GeoExpress Remote Edition, a licensing option that provides unlimited MrSID and JPEG 2000 encoding and manipulation in a Terminal Services or Citrix environment. Users can install GeoExpress on a central server and log in remotely to run GeoExpress. This is of great benefit since imagery can now be stored in a central repository so remote users no longer have to copy large images to their local drive. Multiple users can run GeoExpress concurrently and perform intensive image processing jobs such as compression, reprojection, or color balancing on the server, freeing up their local machine for other work.
Does GeoExpress work with other GIS applications?
GeoExpress is designed for interoperability with the widest range of leading geospatial applications from ESRI, Leica Geosystems, Autodesk and Intergraph, MapInfo, Bentley, and GE/Smallworld, to name a few.
I've been happily using JP2 for my multispectral images for some time now. What is the advantage to using your new MG4 multispectral support instead?
MrSID Generation 4 is LizardTech’s format, meaning that all software that supports MrSID does so through our Software Development Kit (SDK), providing consistent display and performance. There are many inconsistencies involved when using such a complex open standard as JPEG 2000. For example, a JPEG 2000 file may not display or behave consistently across all JPEG 2000 software because different manufactures must write their own JPEG 2000 viewers and writers, which may not support certain features of the JPEG 2000 specification.
