I can hardly keep up with developments to talk about here. A few weeks ago we released version 8.5 of our MrSID SDK, an update that adds support for per-band decoding. Per-band decoding means that LizardTech’s partners and customers now have the ability to decode only the bands that they need from multi- and hyperspectral imagery, which can greatly improve decode and viewing performance.

The new version also supports several additional platforms, including iOS 4.0, both 32- and 64-bit versions. I had it on my list to blog about that, but now ClearTrust, a Reston-Va.-based company that develops geospatial tools for the Macintosh and iOS devices, has already used our SDK to integrate support for the latest version of MrSID (MG4) into version 1.2 of its CartoMobile® field data entry and visualization application, so that CartoMobile users can now view MrSID imagery on devices such as iPhone and iPad. That’s bound to make iOS loyalists happy.

There’s good news particularly for Linux users, too. The new version of the MrSID SDK supports Red Hat 6, both 32- and 64-bit versions. For more information about the MrSID SDK go to www.lizardtech.com and log in to our Developer website at the bottom of the page.

You may already have heard, but now you can view imagery compressed to MrSID and JPEG 2000 formats on your iPad. Folks in the industry are excited and we’re already getting positive feedback about the functionality this application brings to users. Glenn Letham at GISuser picked up our news item today and Matt Ball at Spatial Sustain even wrote a little thing about how the app extends image portability. Thanks guys!

Here are some of GeoViewer’s intuitive, easy-to-use features:

• Open MrSID and JPEG 2000 images.
• Select bands to view from a multispectral image.
• Explore imagery by panning, zooming and zooming out.
• Add vector overlays (Esri Shapefiles and KML files) to get more out of image layers.
• Center on your GPS location so you can see what’s nearby.
• Measure the distance between a series of points.
• Identify geolocation by touching on any image.
• View layer properties, including coordinate reference system, geo bounding box, dimensions, colorspace, datatype, and resolution.
• Search by geographic coordinates in WGS 84 (Lat/Long) or the image’s native coordinate reference system.
• Set viewing preferences (band selection, layer line color, etc.).

The GeoViewer application for iPad is free and can be downloaded from the iTunes App Store. Get busy!

Just when you were saying to the person in the next cubicle “I don’t see how they could make GeoExpress any better”, along comes GeoExpress 8.5. We’ve been listening to our customers’ feedback again, and one of the things many of our customers asked for was the ability to compress image bands individually.

Done.

We’re still listening.

The latest version of GeoExpress not only enables you to select which bands from a multispectral input image you want to include — and in which order — in your output MG4 file, but allows you to compress individual bands or even groups of bands at specified ratios. So, for example, for MG4 output you can compress the R, G and B bands of your 8-banded source image at 20:1 if you want, while leaving the other five bands lossless. We call these features “band selection” and “per-band compression” and we’re sure that anyone using multispectral imagery will find them to be useful advancements.

There’s more. We streamlined our Coordinate Reference System selection tool so that specifying a CRS for source and output images is easier and takes less time. And for those of you administrating GeoExpress with a license server and floating licenses, version 8.5 gives you greater control over your licenses by allowing you to specify how many of your floating licenses can be checked out as commuters and taken off the network. We also fixed some stuff — you know, little under-the-hood things you probably don’t care about (they’re listed in the Readme file if you do).

All in all, we’re pretty pleased with GeoExpress 8.5, and we’re eager for you to take it out for a drive and tell us what you think. Get the trial download at http://www.lizardtech.com/downloads/trials.php or contact your LizardTech representative.

Okay, NOW we think its impossible for GeoExpress to get any better. Of course, we haven’t yet finished reading our latest batch of customer mail…

LizardTech’s business is not only about compression ratios and lossless quality; it’s about making our customers’ jobs easier by providing the best GIS solutions around while still taking into account their current operations. While much of our team’s time during the last ten months has been spent building and launching LizardTech’s GeoExpress® and Express Server® software products, we’ve also worked (and continue to work) hard to ensure that these products remain compatible with other commonly used GIS software.

Based on your feedback, we know many of you manage workflows that include one or more pieces of Esri software and it is increasingly important for both LizardTech and Esri technologies to integrate seamlessly together. Supported file formats allow projects to run smoothly and make sharing data faster and more efficient. Everyone wins.

To that end, LizardTech has recently made available a free plug-in for interoperability between our Express Server and Esri’s server product, ArcIMS. Express Server 7 came on the scene in July offering exciting features such as added support for raster images encoded to MrSID Generation 4 (MG4™) format and the option to install as a 64-bit application. Now when used together, Express Server makes viewing images via ArcIMS up to 25 times faster!

We also offer free plug-ins that add support for MG4 raster data files in Esri’s ArcGIS Desktop version 9.3.1 and 10. Now Esri’s Arc users can harness the benefits of the new MG4 files that GeoExpress 8 produces, including support for compressing hyperspectral data allowing users to compress up to 255 bands of geospatial data.

You can download the plug-ins for ArcIMS, ArcGIS Desktop 9.3.1 and ArcGIS Desktop 10 here.

We greatly appreciate your feedback and suggestions for future releases, so thank you, and keep it coming!

We Lizards like to keep busy and we like to share the products we develop with the geospatial industry, because…well…geospatial users are just so appreciative! Hard on the heels of the release of Express Server 7, which can be installed as a 64-bit application and features support for MG4 imagery, LizardTech has unveiled the MG4 Plug-in for ArcGIS 10 Desktop.

MG4 was created to support multispectral imagery and alpha-band transparency, and it is the fourth generation of LizardTech’s MrSID format. It has been met with enthusiasm by both end-users and developers. And the new MG4 Plug-in gives users of Esri products support for multi- and hyperspectral imagery compressed to MrSID format within the applications they use every day.

And, it’s free!

Let us know what other products you’d like to see that would make your job easier. We take our customers’ feedback seriously.
