LizardTech software architect and occasional Zoom blogger Mike Rosen and I put together an article for GeoWorld about LiDAR data — why LiDAR is so big (both in file size and in popularity), the havoc that its size has caused in efforts to harness its impressive imaging power, and the various ways the geospatial industry has attempted to bring this leviathan to its knees.

The thing about LiDAR. Hot off the press.

Among other things, Mike is lead developer on our LiDAR Compressor project, so his insight into the challenges that LiDAR presents the industry with is keen, and since he’s been with LizardTech since MrSID was very young, there are ways, he notes, in which this is a familiar story.

The article is called “The Inaccessible Plenty: Trying to Tame LiDAR’s Largeness.” Read it here.

And if whopping LiDAR point clouds are your cup of tea (or your cross to bear, or even a horror that you just can’t pull your eyes away from), GeoWorld’s editor, Todd Danielson, will be joining us Thursday, January 24, for a webinar with our own geo-jockey, Robert Parker*, to hear the good news and follow up in a practical way on the lessons learned in the article.

We won’t run out of virtual chairs, so sign up and then drop in to pick up some LiDAR Compressor best practices. Webinar details are here.

*Actually, Robert is our sales engineer, but his renown as a calm, reassuring webinista who can put you at ease with LizardTech’s powerful suite of geospatial software products through the simple medium of a shared desktop has led him to consider a second career as a high-tech spiritual guru.

We’re pretty pumped. Why? Well, we always are — that’s how we make such great software. But in particular, our white paper on the MrSID Generation 4 (MG4™) technology has been republished by the good folks at GeoPlace.com, so that word about the format’s new features — support for multispectral imagery, alpha band transparency, support for LiDAR point cloud data and improved mosaics — can reach an even wider audience of users.

If you haven’t seen it yet we encourage you to read it and learn about the capabilities of LizardTech’s latest version of the format that first made it possible for geospatial professionals to use high resolution imagery in their applications and that continues to evolve with advancements in geospatial imaging.

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/.)

The newly released MrSID Decode SDK is really two sets of libraries and tools in one package. And part of it was released more than a year ago under another name. Hopefully, geospatial professionals have more to do than wonder why this is, but for those with light workloads or long memories, here’s some background that we hope will address any confusion you may have.

In 2009 LizardTech introduced an updated version of the MrSID format that the geospatial industry has been relying on for years. We called it MrSID Generation 4 (MG4) and we released a “decode SDK” so that developers could begin building supporting for MG4 into their applications.

What was most unusual about MG4 was that it was a version of the format specifically updated to support the compression of LiDAR data. That is, the SDK enabled support for files compressed to MG4 using LizardTech’s LiDAR Compressor software. MG4 (and its SDK) would not support raster imagery for another year, during which we returned our attention and energies to GeoExpress, our raster image toolset and compression engine, to evaluate and implement the features our customers most wanted in the way of new features.

GeoExpress 8, with its support for alpha bands and multispectral imagery and its improved mosaicking, is a product we’ve long been excited about releasing. It came out in November of last year, and it looks as though our customers have once again steered us straight about the features that are most important to them, because the response to the new release has been very enthusiastic.

In the wake of the GeoExpress 8 launch, we’ve just released the decode SDK that combines MG4′s LiDAR capabilities with support for the new raster advancements in GeoExpress, bringing the MG4 story into full resolution, as it were. The updated SDK is called the MrSID Decode SDK, and as we noted at the beginning it’s really two toolsets in one. However, the toolsets are designed to work together. For instance, we include a sample application that shows you how to easily determine whether a file is composed of raster or LiDAR data and then shunt off the processing to the correct section of the SDK.

When you download the MrSID Decode SDK you have everything you need to integrate support into your applications for either LiDAR data or raster imagery in the MG4 format. It also enables support for viewing and decoding imagery compressed to both of the classical versions of the format, MG3 and MG2.

It’s an exciting season to be working with compressed LiDAR and raster image data. We’re happy to be making tools that developers can use to make their applications more useful to more geospatial users. The MrSID Decode SDK is available for download on our developer website.
