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.

At this year’s Esri User Conference we asked our customers, who love our plastic lizards almost as much as they love our software products, to submit a story either about their experience with GeoExpress or about lizards — live or plastic — and we’d pick a winning story from each pile. We got a lot of amazing stories.

Okay, Tyrannosaurus is not a lizard in the scientific sense, and none of the stories were about T. Rex.

Thank you to everyone who participated.The authors of the two stories we selected as our favorites each win an iPad.

With a classic narrative of struggle and triumph that we never get tired of, Matthew Woodworth of TranSystems in Kansas City, Missouri writes:

My organization deals with fairly large amounts of raster data, and a very small storage budget.  About 2 years ago we were confronted with the situation that, not only had our server dedicated to store our raster data become completely full, but we had nearly 1Tb of GeoTIFF data provided by a client sitting on an external hard drive and nowhere to store it on the network. 

We looked at quite a few options to fix the issue including expanding our network storage, when we came across GeoExpress by LizardTech. My IT department was very impressed at the idea of compressing existing data to reduce storage space and I, being the GIS department head for my organization, had used MrSID files for years and loved the idea of not being forced to store my data offline.

We decided to purchase GeoExpress Unlimited and have never regretted it. I went from exceeding my server capacity by 25% to having nearly 65% free space afterwards without losing any information. As of the date of this letter I have not quite utilized 50% of my capacity after over a year’s worth of adding data.

Thank you LizardTech.

And from Thomas Hardy’s own Wessex region in England, Andy Nicholson of Wessex Water in Bath asks the thrilling question:

My GeoExpress Lizards – Thiefs in the Night or Innocent Bystanders?

Every quarter we complete MrSID conversions for distribution across the GIS fileservers. Last year in the office not only did we notice we were getting older – our recollection of the required settings for MrSID file creation had got so bad they had to be written down – but we also started to doubt our own sanity. It all started when someone left a Mars bar on my desk. The next morning we all noticed it showed signs of being nibbled by some small creature. We also noticed that the two LizardTech lizards that sit atop my screen – one green the other green and orange – had swapped sides.

For several days we observed they moved sides and each tasty treat we left for the “thief in the night” was nibbled or eaten completely. It was time to catch the culprits “red clawed”. We positioned a web cam to capture the crime scene. For a couple of nights nothing, then one night much to our relief we caught the thief in action:

In flagrante delicto.

The LizardTech lizards were proven innocent. Mind you, to this day we don’t know how the lizards changed sides on top of my screen.

Congratulations to Andy and Matthew. And again, thanks to all who sent us stories. We’ll see you again at next year’s user conference if not sooner!

We’re excited about the release of Express Server® 7 image serving software. You already know that Express Server is the fastest, most stable, and easiest way to distribute high-resolution raster imagery. Who doesn’t know that? But what you may not know is that besides running as a 32-bit application as it always has, Express Server also can be installed as a 64-bit application on 64-bit systems, which means you can take full advantage of increased memory for performance gains.

Express Server 7 is available now.

And that’s just one reason to look at the new version of Express Server. Here’s another: support for MG4™, the latest version of LizardTech’s MrSID® image format. Through the use of alpha bands, MrSID Generation 4 enables true transparency, which means Express Server 7 can deliver better looking mosaics.

Even more exciting, MG4 supports multi- and hyperspectral imagery, and Express Server 7 enables you to specify any three bands to serve out. You can create any number of band-mapped catalogs so that any image in a given catalog will be served with your desired band arrangement. You can also use the same image for any number of band groupings. This gives you unprecedented flexibility in serving imagery for your geospatial end users.

We hope you like Express Server 7 as much as we do. If you’re at the 2011 Esri User Conference this week, stop by and visit our team at Booth #1311. They’ll be happy to talk with you about image delivery or any other needs you have.

LizardTech is moving toward more frequent releases and a bit more of an agile development schedule. We decided we could use a dedicated engineering manager to focus on the issues inherent in quicker turnaround and we found that person in Rich Estrin.

Bringing software products to market.

Rich is a guy who’d rather be developing software products than talking about himself and having his picture taken, but we did get some info out of him so that you’ll have some conversational hooks to engage him with when you start seeing him in the LizardTech booth at trade shows.

For one thing, he’s a vintner. That’s right, he and his wife are winemakers. They own a fully functional and licensed winery and run the cellars out of the basement of their home in Issaquah, where they live with their two kids. Their first commercially available red will be released at the end of this year.

The Grape Whisperer.

Rich brings over 17 years of commercial software development experience to LizardTech, with the last twelve years increasingly focused on leading software teams and projects. He has worked with a broad range of technologies and domains from enterprise life science research software to desktop business software. Rich earned a BA in Computer Science from the University of Washington.

We’ve had some emails from people who are having trouble viewing MrSID images in Esri’s ArcGIS Explorer. We dug around and found out that our friends at Esri had already been notified of the same issue and they’d already discovered that the problem was undefined projections. MrSID images are sometimes created from TIFFs that have no projection information, or the projection is written to an AUX (.aux) file but not included in the actual MrSID image.  

Esri has posted an article on how to fix the problem for immediate viewing using ArcCatalog. Click here or enter this URL in a browser:

Of course, defining the projection in ArcCatalog only writes the information to an AUX file, not into the MrSID file itself, which would be a better practice. Users should ask their data provider to include the projection system (LizardTech’s GeoExpress® software calls this the coordinate reference system or CRS) in the metadata of the MrSID files they deliver.

As for any images you have already, if you know what their projection is and have access to a licensed copy of GeoExpress, simply add any number of MrSID images of the same projection to the GeoExpress Edit Metadata tab and specify that projection for all of them at once.

Adding projection information to images by using the Metadata tab in GeoExpress. Click for a larger version.

To edit the metadata of existing MrSID images using GeoExpress:

1. Load images into the Edit Metadata tab of the Job list.
2. Select applicable image(s) and choose Metadata from the Options menu. The Metadata Manager dialog appears.
3. Select the Image tab. Click Select Coordinate Reference System. The Coordinate Reference System Selector appears.
4. Select a projection system using the drop-down menus and then click OK.

You can also use the GeoExpress command line tool mrsidgeometa to add a well known text (WKT) string. The syntax is as follows:

mrsidgeometa.exe -f <filename.sid> -awkt <WKT string>
