The course, which is the first of its kind in Yemen, includes a field survey on the buildings and the various components in the historical cities.

Trade user conference attendance has been light this year, to say the least. As a result, trade conference organizers for individual vendors have taken different routes to get their product message out to their users. Some vendors have posted videos of their keynotes and some technical sessions. Bentley Systems opted to cancel their live BE User Conference in favor of what they call “Bentley Connected,” an online offering of content featuring best practices presentations by users and other industry leaders.
In conversation with Chris Barron, vice president for corporate marketing, Barron noted that in a live conference, they had all this “terrific content” but the conference was over within the week and they didn’t have a program to promote the content even after they posted it online.
“When we were planning our conference for this year, we lined up more great speakers but we were also hearing from a lot of people in the industry among our users, that their travel budgets were being cut this year,” Barron explained. “We started to think about what we could do to extend the reach of this good content that was being developed and make it available to a much wider audience rather than the 2,000 people who might be able to attend a physical conference.”
What came of it was the BE Connected conference, in operation since the third week in June. “We have about 150 seminars lined up and about two-thirds of those are Best Practices, the other one-third are presented by Bentley colleagues, generally about specific products.” Barron assured that the presentations were all “educational” not just sales pitches. BE Connected is an attempt to users keep up with trends in the industry and best practices and find out what’s happening with technology without the expense of traveling to a conference.
Every week 6-9 new seminars are added to the website. Live Q&A has been made available on demand, after the initial streaming of the presentation. This way an audience in different parts of the world can access the presentations when it’s convenient for them.
“We are tracking what seminars people have attended, and keeping a transcript that’s available to them so they can track their own professional development through the process,” added Barron.
The content is arranged around different tracks: bridges, roads, power generation, building structures and building energy performance, BIM.
Will the BE Conference return in the future? “This is a response to the economy this year, but we are planning to have a face-to-face conference in the future,” Barron replied. “But I also think we will continue to have this element of outreach and education as an ongoing fixture in terms of our web community.”
Barron said Bentley is seeking ways to leverage new technology in different ways. In the future, presentations may become case studies, or become discussion topics on their community site, or generate ideas for future seminars. “It’s all about reusing content and making it available as widely as possible.”
They are also working on language presentations for geographic regions that are underserved such as China and Brazil.
My take on the user conference situation:
The new element of outreach is definitely a value add for Bentley and their users. The content on the site is rich and will serve attendees well. However, it would seem there is no replacement for face-to-face contact, nor the commitment of being at a conference and trying to make the most of your time there.
What I have found at the user conferences I’ve attended this year is that users really feel the user conference experience is valuable – valuable enough that for some bigger conferences, some attendees are willing to pay their own way to attend when their companies don’t have the budget for it.
The act of making a plane and hotel reservation, organizing the time away from the office, places an attendee in a particular position of focus for the event. Visiting a website, although valuable, is not going to have the same takeaway value.
Perhaps one way of bridging this gap would be to have periodic announcements of what is being featured on venues such as BE Connected, so that attendees would not need to remember to see if there was something upcoming that they were interested in.

According to president of Galdos Systems, Ron Lake, KML and GML have different purposes – KML is a language for describing visualization and also a browser control language, and GML is about describing kinds of geographic objects. There are no feature types in KML so you cannot differentiate different types of roads, for example, whereas that is the purpose of GML. “You can look at GML as a way of modeling or encoding geographic content so you can have kinds of objects like buildings or schools,” explained Lake. “Then KML is a way of presenting that content visually.”
“Styling” rules are applied to create KML that provides a visual presentation of geographic data in GML. For example, in looking at the GML you have roads with four lanes and road with two lanes, and gravel roads and paved, and you can make a rule that if the road is paved with four lanes then you can generate a default in KML that will draw it as a black line and if it’s a two lane draw it as a red line. This way you can use rules by which you interpret the geography for visual presentation and then you use those rules to generate the KML.
“KML is still rather limited,” said Lake. “If you’re a cartographer or traditional kind of mapmaker you might be kind of dismayed that KML doesn’t support things like dash lines or railroad tracks. It’s still fairly simple but you can do all this interactivity, which compensates for part of that.” Similar issues exist in 3D, for example, “CityGML is a multilevel of detail modeling language so you can model cities with a very coarse level of detail but it’s not really intended for visual presentation. For this you would style CityGML say into something like Collada, .obj or x3D which are the encodings that are used by Google Earth and by Microsoft Virtual Earth 3D.”
“The idea is to try and separate your modeling of the world from presentation so that you can as be as flexible as possible in terms of how you present content. You might have the same geographic data and you might present it quite differently for a civilian audience vs a military audience even if it’s the same information.”
There was a lot of buzz about cityscapes at ESRI this year, but the place that will really focus on this topic will be GeoWeb 2009 in Vancouver, starting Monday, July 27th.
According to Galdos Systems CEO and GeoWeb organizer Ron Lake, last year they started the idea of cityscapes with a focus on CAD and GIS integration.
“This year we’re focused more on SDI and data sharing in urban environments,” said Lake. “To do that, we have invited speakers like Ken Greenberg, an urban planner for the City of Toronto, a well known architect, talk about collaboration and building cities.”
In that context, information sharing involves the collaboration of both machines and people. “We also have speaker David Bolocker, CTO at IBM, who will talk about collaboration software research that IBM has been doing,” said Lake. “Then we have John Stutz, co-founder of Tellus Institute of Boston, an organization that does scenario planning, which in their case involves numerical modeling of global processes – population, climate, and potential scenarios for the evolution of the earth. They also did a big study for the city of Boston.”
Javier de la Torre, CEO at Vizzuality, Madrid, Spain, will speak on his project called the Encyclopedia of Life, which endeavors to catalog location, time and extent of every species, incident, and all biologists’ or others’ reports on the presence of an animal or plant species.
This year the conference also includes an Academic Science track. Some of the papers from the conference will be published in the ISPRS Journal.
The conference includes an all-day course entitled GeoWeb 101 which will answer questions such as, why does GML exist, or what is the difference between GML and KML?
The Health & Human Services ESRI User Group (HUG) was founded 11 years ago and is now the second largest ESRI user group, with 1041 members in 36 countries. The Healthy GIS newsletter http://www.esri.com/library/newsletters/healthygis/healthygis-winter2009.pdf is available online.
During the lunch meeting held at ESRI UC, the group outlined recent inquiries which included: obesity, tuberculosis, and methodology. It was also pointed out that health reform cuts across all geographic boundaries.
The Health User Group Conference will take place this year September 22 in Nashville, TN (http://www.esri.com/healthgis).
The conference will take place in Denver in 2010.
Setting: the ESRI UC newsroom.
Guy comes into the room. “Is this a place I can check my email?” he asks.
I reply, “No, it’s the Press Room. You can check your email down the hall.”
“What does ‘press’ mean?” he asks.
“In this case, people who are journalists, writing specifically about the GIS industry,” I answer.
“What do they write?” he asks.
“Magazine articles and newsletters, primarily,” I say.
He touches his GeoTweet button. “What about tweeting? Does tweeting count?”
“No,” I reply, a bit incredulous. “Anyone can tweet.”
“Anyone can write an article,” was his response.
“Maybe these days, that’s true,” I say, well aware that I’m living in the age of bloggers, tweeters and anyone else who feels they have the right to speak authoritatively (or not) on any given topic.
Of course, many more salient retorts came to me after I had left the room. Just imagine how crowded the Press room would be if filled with tweeters at the conference!
I became a writer during a period of history when it was relatively challenging to become published. To find a publisher for your books was not something that just “anyone” could do. Many good writers were turned away because their work “didn’t meet editorial needs.” Does anyone remember what a “rejection slip” is?
Now there are courses on how to publish for yourself, and anyone can set themselves up with a blog. Twitter is even easier – just write one line about anything, and you can see your name, or user name, in print.
Although we have created these easier to use venues for people to express themselves freely, I think it’s important to not lose sight of the difference between a tweet, a blog, a magazine article, a book, and a newsletter.
Generally, writers are paid to write magazine articles, books and newsletters. Those writers have gained a certain credibility by writing, earned either in their field of study or in journalism.
One vendor at ESRI noted that the “NextGen” generation of people don’t care if the information they disseminate is accurate, they just feel that they should disseminate information. Twitter gives them the opportunity to do this in short bytes. A blog can also contain anything from how they are feeling that day to actual useful information about technology, weather, location, etc. It’s up to the reader to determine if any of this information is relevant. For vendors, tweeting may contain some crowd-sourcing information.
So this commentary is not just about writing: if you look at what most vendors are generating these days: easier-to-use, quicker, accurate – they are looking to appeal to a wide audience, not just those who are GIS professionals. This doesn’t negate the need for full blown GIS – GIS is the underpinning for each of these easy-to-use technologies as well.
There is still also the need for GIS for the GIS professional.
You might say we are looking at the difference between the “Google Earth gen” and the “full blown GIS gen.”
It would be interesting to know how many GISCafe readers read blogs, post tweets and read Twitter and how often they do this compared to reading an article or newsletter?
The company Wacom has been around for 25 years with its display technology . I was first familiarized with this company through my work in the AEC industry (architectural, engineering and construction) for which it always seemed like a good fit, with its digitizer tablets and sketching capabilities.
Wacom has now come to GIS with its palette-based DTZ-2100 Interactive Pen Display, making a timely entrance at a time when ESRI’s Bill Miller is working with sketch technology, and the whole notion of “GeoDesign” suggests a way of designing GIS with new tools.
Wacom’s Mike Dana said the company is focused on changing the human to computer relationship. The product consists of a monitor or display, a pen and a driver. The brain power is in the monitor, and the pen is not intelligent but understands pen pressure so that the user will have a “canvas-based response.”
Wacom hasn’t worked out just what features you might be able to have with the pen pressure, however, Dana said that this capability, coupled with the pen’s strength of signal and tilt direction could be part of 3D of the future.
Dana said that the display, which has buttons on either side of the screen, can be configured as you wish, and you can execute 8-12 repetitive tasks at a time.
There is also a display toggle so that you can work on two screens simultaneously and the image will map directly to the second monitor.
“This product combines the convenience of touch with the precision of penpoints,” explained Dana.
An ESRI Authorized Business Partner, Wacom’s DTZ-2100 will be hanced with flat templates for ArcGIS 9.4. ArcGIS is added to the list of formats in the driver.
“The display is more accurate and precise than the Tablet PC,” claimed Dana. The specialized behavior of the pen, along with the ability to customize buttons to the workflow in office solutions make this a technology to look at.
I did note that the LCD panel is a big draw on power, however, it is powered separately from a PC. Currently, it is not really something you can take out in the field.
Wacom has two models: a 21.3 inch standard size display and a smaller one. The standard size including display monitor, pen and driver retails at US$2,000 and a smaller one is US$1,000.
Many government and public organizations have spent billions of dollars over the past 20 years building geospatial datasets. The cost of updating these datasets is currently equal to the cost of creating them.
Lawrie Jordan of ESRI moderated an industry keynote given by Roger Mitchell, vice president of program development, MDA federal Inc. formerly Earth Satellite Corp. (EarthSat), which focused on a more effective way of doing change detection that would save government and other entities money. The current method of doing geospatial change detection involves reviewing aerial imagery to determine if a feature has changed, a laborious process, according to Mitchell. The current use of multi-spectral image differencing has the potential for many false indicators.
New change criteria involves the following:
-reliable with an absolute minimum of false indicators.
Developed by the MDA based on patented cross correlation analysis technology (CCA), the new process uses multiple data to filter out false indicators.
The MDA will disclose the algorithm to the U.S. Government. The solution is nearly 100% automated. It uses any moderate resolution multi-spectral image data. .

My day began with a breakfast hosted by ITT Corporation, who announced their new image processing product for GIS professionals. The new product, ENVI EX, is the first image processing and analysis solution resulting from a partnership with ESRI. The product is tightly integrated with ArcGIS, and is designed to be easier to use and integrated with GIS workflows. The demo shown was a classification workflow with vector data in ArcMap. To use it, Richard Cooke, president of ITT’s Visual Information Solutions group, said, you don’t need to know image science. “No longer are imagery and GIS living in separate worlds.”
The addition of Lawrie Jordan, original founder of ERDAS, to the ESRI team has spearheaded the integration of imagery with GIS at the company. This technology integrates the ArcGIS projection engine into ENVI.
The exhibit floor was not as crowded with exhibitors this year, and some exhibitors also said that traffic was light. The Map Gallery also had fewer exhibits than in previous years.
So far, themes encountered on the exhibit floor include: imagery, community input, real-time map, grab-and-go geospatial products.
During the keynote, there seemed to be very few empty seats, so I would guess that attendance is still high for a trade conference in today’s economy.
