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!

Where I go the Lizards follow, or maybe it’s me who’s following the Lizards?

I recently took my family on a long awaited vacation to Maui. When we announced it to the kids back in January, our four-year-old daughter and one-year-old twins, they were ecstatic. (OK, so maybe the twins didn’t really “get it” until we got there, but my older daughter has been excited for months.)

One of the more colorful of the plastic LizardTech lizards.

As a habit, I, the always-prepared-for-anything mom, take lots of snacks and toys on the plane to keep my kids busy so they are less likely to irritate the “can’t stand kids that scream” passengers (nothing against you, I was in your shoes once myself). Among the toys I always bring along the ever-so-popular LizardTech Lizards. They are small enough to fit in my pocket and provide a big enough attraction to keep my kids busy playing with them for a while. Can’t go wrong!

Having arrived at our condo and dumped our luggage in a corner, we were ready to hit the sandy beach! As we were running along the pathway to the water, I stopped dead in my tracks as I saw something small with a tail run across my pathway. Immediately I thought: a rat! Wait — that’s too small for a rat. A mouse? Still, a mouse is a bit bigger. Plus, how dare rats and mice ruin my perfect paradise getaway by showing themselves in broad daylight.

A rat? A mouse? No, an authentic lizard!

Suddenly it dawned on me – it looked like the little plastic LizardTech Lizard I had had to snatch out of my son’s mouth on the plane. Did my husband play a joke on me and tie a string to the plastic LizardTech Lizard and run it across the sidewalk SOMEHOW? No, he was running behind me with the kids (I must get to the water first!).

That’s when a friendly Westin Hotel employee walked up to me asking if I’m OK. I must have had “that look on my face.” I told him what I saw and he laughed with delight saying “what you saw was a little lizard.”

“WHAT? A LizardTech Lizard?”, I asked.

He looked puzzled. “No, a Maui authentic lizard.”

Wow, I thought to myself. I’ve been to Hawaii four times and this is the first time I saw a lizard.

I see lizards…everywhere!

And so my quest to find more “Maui authentic” lizards began. We saw them virtually everywhere, at the park, playground, running across sidewalks, by the pool, on the trees and so on. I even took a few pictures to share. Enjoy and remember, next time you’re in Maui, you’re not alone. There’s a lizard watching you whether you like it or not!

So, this is my story. Since I’m a LizardTech employee I am not eligible to submit this “lizard tale” for a chance to win a swanky new iPad 2 as part of our Esri contest. But you can! It’s not too late, so submit your story today!

Here are all the details: http://www.lizardtech.com/landing/esriipad/index.php

Good luck!

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:

http://blogs.esri.com/info/blogs/arcgisexplorerblog/archive/2009/
03/05/projections-and-mrsid-images-for-explorer.aspx

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>

I recently had the privilege of spending a week in the Denver Metro area visiting LizardTech customers and business associates.  I have been to the beautiful city of Denver many times, and I look forward to each and every visit, especially the part where I get to leave my umbrella at home and bust out the sunglasses! (Yes, they actually sell sunglasses here in Seattle, wise guy…just don’t expect to use them much. )

But something I never seem to adjust well to, no matter how much I prepare for it, is the altitude and humidity change between Denver and Seattle.  As a means of outsmarting my internal self, the first stop as soon as I hit town was to a Super Target to pick up a case of water for the week, in hopes that it would help my system adjust going from 80% humidity at sea level to virtual 0% humidity at 5280 feet. But little did I know that I would experience a new symptom of higher altitudes on this trip – nose bleeds.  As a co-worker based in Denver says: “They don’t call ’em the Denver Rockies for nothin’.”

So with my case of water and a box full of Kleenex I powered through an action-packed week in the Mile High City.

Monday 11 am – Pixxures

It was just me on this inaugural Denver Metro area customer site visit. Pixxures is a very important LizardTech customer. They provide custom digital aerial imagery, orthophotography, GIS and mapping services. In addition to collecting direct-digital, high-resolution multispectral aerial imagery, they scan and orthorectify historical aerial photography and offer value-added remote sensing services.

I was able to meet with all seven people on the production team and go over LizardTech’s LiDAR Compressor and GeoExpress 8 software. They are heavy users of multiband and lidar imagery so LiDAR Compressor and the new multi- and hyperspectral support in GeoExpress couldn’t have come at a better time for them.

Monday 1:30 pm – Mapmart

Terry Ryan and myself on another Denver Metro area customer site visit. Mapmart is a division of IntraSearch Inc., a full service mapping company, headquartered in Denver. MapMart is partnered with over thirty of the top geospatial data creators to cover nearly all facets of geospatial data needs. They are branching into the field of data hosting and are very interested in implementing LizardTech’s Express Server software.

You say you don’t know much about Express Server? Here’s some quick schoolin’ for you:

• Check out GIS Planning’s Express Server data hosting website here.
• Express Server also works within any WMS client as well as a number of proprietary clients. Your imagery is accessed directly within these applications. Check out the entire state of New Jersey here!
• View more WMS imagery being delivered using Express Server here.

Tuesday 8:30 am – CompassTools

It was just me on this Denver Metro area training. CompassTools is an authorized LizardTech reseller located in Centennial, a suburb of Denver. They specialize in field data collection tools and graciously offered us the use of their training room at no charge and even provided a continental breakfast for the attendees.

We promoted this session through a LizardTech marketing e-blast and the CompassTools newsletter.

Wednesday 1 pm – City and County of Denver

Terry Ryan and myself on this customer site visit. We met with Paul Tessar and his team of developers and GIS gurus. They are very interested in Express Server for accessing their imagery using ArcIMS.

Wednesday – ERDAS 11 World Tour

This half-day event was hosted by ERDAS and Digital Globe (another very important LizardTech customer!) at the Xilinx Facility in Longmont. T-Ryan and I learned about all the new features and benefits in the ERDAS 2011 Software Release.

Here is a GISCafe article with a bit more detailed information on the ERDAS 2011 Software Release.

The event wrapped up after lunch (a very healthy and delicious taco bar!) and as luck would have it Longmont is a mere 15 miles from Boulder, famous for its status as one of the most liberal cities in Colorado and located at the base of the foothills of the Rocky Mountains at an elevation of 5,430 feet.

It was a beautiful day in Boulder with mostly blue skies despite some broken smoke signals from the wildfires in the area. The mountain views were breath-taking and there are a multitude of hiking trails and climbing for all skill levels throughout the city.

Thursday evening  – Business Dinner at Euclid Hall in LoDo District

Built in 1883 as a house for Dr. Byron Albertus Wheeler, Euclid Hall has been home to the Masons, the Colorado Women’s Relief Corps, The Cootie Club, Maudie’s Flea Market and is even rumored to have once been the very fancy headquarters of a brothel catering to government officials, law enforcement and members of the media. Perhaps its most memorable occupant was Soapy Smith’s Double Eagle Bar which operated from 1977 through the end of the century. The bar was a long-time gathering place for good food and live entertainment, with focus on high quality and innovative pub food from around the world including housemade sausages, po’ boys, poutine and schnitzels.

They’ve since taken the stickers off the new windows of Euclid Hall. Image copyright Lori Midson, used with permission.

That said, I had to try the Sausage Tasting plate.  It came with four types of mustard, two sweet and two spicy and a link of each of the following:

• Beef Short Rib Kielbasa – beef blood infused sausage
• Uncensored Hoppwurst, Carr Valley cheddar
• Boudin Noir, avec curry e aubergine
• Bavarian Veal Weisswurst

They did offer to substitute the blood sausage for one of the other three they offered but since I had never had it before I decided to take a walk on the wild side and give it a try. All the mustards and sausages were delicious but I just couldn’t get past the color (it was a deep purple, almost black) and texture (pasty, pâté-type consistency) of the blood sausage enough to enjoy more than one bite.

But rest assured I will be going back to Euclid Hall. The service was amazing and I still have yet to try their famous poutine.

Friday 9 am – Sanborn

Jeff Young and myself on this Colorado Springs customer site visit. Sanborn is our biggest commercial GeoExpress user. They are headquartered in Colorado Springs with locations in Oregon, California, Texas, Michigan, Missouri, North Carolina, and New York.

Jeff Young, our business developer, and I were invited to meet with the productions operation group and discuss the new features in GeoExpress 8.  We were given a tour of the office and got to see the many server rooms they have designated just for image processing. They handle so much imagery that they not only have workstations processing overnight, they actually have a graveyard shift of imagery technicians performing digital orthophoto processing.

Good news, LiDAR users. Our friends at GeoCue Corporation have announced that they’re integrating support for the MrSID Generation 4 (MG4) format into their popular LP360 software applications. GeoCue is the parent company of QCoherent Software LLC, the makers of the LP360 product line.
 
This means that geospatial professionals using LP360, a LiDAR software extension for the Esri™ ArcGIS environment, will be able to efficiently input and decode LiDAR data that has been compressed using LizardTech’s LiDAR Compressor™ software. MG4, the latest version of the MrSID format, accommodates new GIS technologies by supporting multi- and hyperspectral imagery, LiDAR point cloud data, multiterabyte datasets, and other innovations.
 
GeoCue’s customers have asked them for tools to input, decode and view compressed LiDAR point clouds, says Lewis Graham, the company’s president and CTO, noting that now they’ll be able to do so easily.
 
We’re excited about the integration, too, because one of our objectives is to ensure that MrSID files can be used in the widest possible array of applications used in our industry. Now LP360 users will be able to handle compressed LiDAR datasets in ArcGIS, which adds to the number of applications that support MG4. (You can find a complete list under “Third Party Integrations” at http://www.lizardtech.com/products/lidar/.)
