For ikke så længe siden forudsagde jeg at GIS var som skabt til skyen, men at det ville tage tid inden den nåede derop ... Heldigvis tog jeg fejl ;-)
A while back I predicted that GIS would be great news in the cloud but did not see it coming for a while ... Fortunately I was wrong ;-)
Geographic Information Systems (GIS) applications have been moving into the cloud with increased momentum but like other fields where software drives the business model, the move from complex software to the software as a service cloud model was slow to catch on due to the business of delivering software—not the technological constraints of doing so. This presents a new market for those previously locked out of GIS due to high startup costs and a potential paradigm shift for how this niche segment of the software industry does business from now on. The GIS example is representative not only of how large-scale application areas are tentatively approaching the cloud from a technological and business model standpoint, but how such shifts can begin to have an instant impact on the new user groups enabled by the delivery model.
The diverse field of Geographic Information Systems (GIS) has seen greater demand for its wide array of geospatial technologies, not only because the mainstream internet has allowed for a much richer, more inclusive way to map just about anything that is a noun via a sort of unconscious crowd-sourcing of metadata and geotagging, but because the applications for such data are growing. GIS technologies have traditionally been used in predictable ways in the foresntry, civil engineering and development areas, as well as in natural resource exploration and the culling of general population data for use by agencies and organizations of all sizes and purposes. As mapping has become more detailed and the underlying technology behind it more powerful, GIS has been increasingly used in marketing and consumer trend identification—and you can let your imagination take you from there.

En tilfældig Top10 liste fra dette års ESRI brugerkonference ...
One of many Top10s from this years ESRI UC ...
- Sounds like ESRI is beginning to embrace crowd sourced data and social media. So much for the argument that crowd sourced data isn’t useful because it doesn’t originate from an “authoritative source”!
- ESRI is publishing their REST Interface as an Open Standard like they did the Shapefile
- World Topographic Basemap provides a seamless worldwide basemap at many scales from data compiled from many sources. The cartographic quality of this basemap is excellent.
- It comes as no surprise, but Cloud computing is clearly a big part of the future for ESRI.
- I thought the ability to create PowerPoint like presentations in ArcGIS Explorer Online was a nice addition.
- ArcGIS for the iOS on the iPad. The interface is really sweet! Business Analyst Online a free application for the iPhone.
- Lots of new functionality and performance improvements in ArcGIS 10 Desktop.
- Social and Community Analyst product coming this Fall. Built for policy makers who need rich information and analysis. Available on the desktop, online, and server.
- I think Jack mentioned that this is the largest gathering yet for the UC. Never heard an exact number, but just walking around it certainly felt as though there were more people than in the past.
- Enjoyed the keynote from Richard Saul Wurman, et al. Quite different from past keynote presentations. Never thought I’d see Johnny Cash at the ESRI UC!

The 30th ESRI International User Conference was the largest gathering of the GIS community the world has ever known. I sat in the plenary today with representatives from 134 countries representing 6,000 organizations and heard how GIS infrastructure is changing collaboration for doing work and managing the enterprise.
Jack Dangermond, ESRI president, welcomed the attendees by encouraging us to get to know each another as a community. He then acknowledged the 200 winners of the Special Achievement in GIS (SAG) Award for outstanding work in their organizations and industries.
He gave the Making a Difference Award to the Government of Abu Dhabi, United Arab Emirates, that uses GIS for managing cities, utilities, health, response, and science. Abu Dhabi has also provided technology and expertise to the global community. His Excellency Mohammed Ahmed Al Bowardi, secretary-general executive council, Abu Dhabi, accepted the award.
Dangermond also acknowledged the work of the United Nations, especially its cartographic and statistical unit that has diligently worked to bring standards and templates to build a foundation for GIS users throughout the world.
Dangermond talked about his vision of GIS opening the world for everyone--the theme of the conference. "GIS already organizes our geographic information; it is time to share this with the world. Can this be done on a global scale?" he asks. "Converging forces of advancements in computers, the Web, mobile devices, real time measurement and GIS software are making this possible. A Web-based geospatial platform is emerging that is a distributed network of data and services."
The newly formed business City Sourced showed its creation of apps that enable people with location devices to see and report information, allowing them to become involved in their communities and for cities to interact with their citizens.
"Everyone is getting more involved in crowd sourcing and social media," noted Jack. "For example, Twitter tweets can now be georeferenced. There are huge opportunities to bring in new types of real time information from citizens. Responding to these opportunities takes collaboration for sharing data and technology. The geospatial platform is emerging to handle this. In terms of technology, we are about there. Now comes the fun."
"ArcGIS 10 is a complete system for geographic information, for pervasive GIS that is in the cloud, in the office, and in the field. Intelligent maps simplify the complexity of GIS (tables, metadata, workflow, etc.) and hide it behind a map. Geographic information is more than the data--it's all the pieces behind the maps that enable us to share our stories and get our ideas across to others."
"ArcGIS has hundreds of improvements such as fast display, templates, template-based editing, integrated parcel management, map books, and online resources," Jack said. "This makes for a stronger scientific platform for time awareness, advanced spatial analysis, integrated scientific programming, and 3D GIS."
ESRI technology experts demonstrated how ArcGIS is a system that can be used in a wide collaborative effort wherein the enterprise is connected to everyone else. Look for information about these among the UC plenary blog posts, or watch the videos at www.esri.com/uc. These include demonstrations on community maps, ArcGIS Online, ArcGIS.com, IOS for iPhone and iPad, productivity in ArcGIS 10, the integration of Python scripting (Bob Pool of Clark County, Washington), imagery, GIS processing integration, ArcGIS Network Analyst, and analysis using 3D and new space and time enhancements. Also, Barney Krucoff, geospatial technologist for Washington, D.C., talked about the value of contributing data to ArcGIS online.
The President's Award was given to the City of Frisco, Texas, which has embedded GIS into the structure of the community from the school district to health care, to incident response. Paul Siebert, the city's assistant fire chief, came on the stage to the sound of flashing lights and alarms. Dressed in firefighter gear, he showed all the ways GIS is used in responding to an early morning smoke alarm from the high school: routing, the water system, real time camera feed, and the facilities plan. Susan Olson, City of Frisco, information services and GIS manager, accepted the award.
The Lifetime Achievement Award was presented to Carlos Salman Gonzalez, the president and CEO of Sistemas de Informacion Geográfica S.A. (SIGSA). He brought modern mapping tools to Mexico. He also purchased a nursery and led a movement that has planted millions of trees in that country. After working for the Mexican government, Carlos opened his own mapping company, which today is the largest mapping company in South America.
National Geographic Society's board chairman Gil Grosvenor awarded the society's highest honor, the Alexander Graham Bell Medal to Roger Tomlinson, the father of GIS. "The award honors Tomlinson's qualities of great innovation," said Grosvenor. "His efforts have made geographers out of people who didn't even know they were geographers." He also awarded the Alexander Graham Bell Award to Dangermond for his innovations that are transforming the world of geography, bringing the use of geographic information to every part of the globe.
Big Fork High School students Tia Bakker and Ernie Cottle from Montana took the stage wearing caver helmets. They explained their GIS analysis of cave natural resources inside Glacier National Park. Their teacher and GIS mentor Hans Bodenhamer encouraged the many GIS professionals in the audience to volunteer as GIS mentors to the youth in their communities.
Richard Saul Wurman, author of 80+ books and founder of the renowned TED conferences gave the keynote presentation. Wurman discussed the project19.20.21 and how GIS is used to answer the questions--where is a city's center, where does it end, and how do we determine its edge? The way we ask the question is extremely important. He talked geospatially about five factors for analysis: concrete density, geopolitical area, transportation basin, metropolitan statistical area, and city lights. Wurman hopes to eventually develop a standard for measuring cities so that they can be analyzed and compared around the world.
There is beauty in the world.

Jeg har i flere omgange postuleret at 80% af al information har en geografisk reference ... og at de resterende 20% er information hvortil denne endnu ikke er identificeret ... Når nogen nu postulerer at 95% af al data har en geografisk egenskab betyder det blot at vi nærmer os målet .../Sik
When delivering session I've often said that 80% of all data have a spatial reference ... for the remaining 20% we just haven't yet identified the spatial reference ... Stating that 95% have spatial reference just indicates that we're getting closer .../Sik

Med udsigt til en plads i skyggen ...
Shadow on the wall ...
ArcGIS 10 is a complete system for 3D GIS. Gert van Maren and Nathan Shephard of ESRI took the UC plenary stage to show how 3D GIS is used to analyze virtual city models and consider the impact of a proposed redevelopment project.
Using data from the City of Rotterdam in the Netherlands and TeleAtlas, they created a virtual city model. Using the ArcGIS Explorer tool, Gert performed a fly over of the city to give the audience a sense of the city while he zoomed in to areas of interest. Next he focused on the peninsula, where architects have proposed 5 new high rises. The public has raised concerns about the visibility and impact of these buildings, specifically their shadows.
Using the 3D editing environment to answer the visibility concern problem, Nathan ran a line of site analysis using ArcGIS 10 Desktop and determined the visibility from the road point of view, which is visualized in GIS. Significant visibility is calculated for each building against every 5 meters of the major roads. The results were displayed on the map.
To answer the question about how the shadow will impact neighboring buildings, Nathan used a python script model for calculating sun positions with an attribute for every hour of the day based on sunlight at the winter solstice. The results were shown on a map, and the 3D representation revealed when and where building shadows would impact their neighbors.
The analysis was loaded to the cloud so that people can view and interact with it from any Web-enabled device.
Using an app on a mobile device such as an iPad, a person can click on the buildings and retrieve attribute information from ArcGIS Server such as height, building name, and before and after visibility and shadow scenarios.
A 3D shadow analysis showed the shadow cast of existing buildings in grey, and of proposed buildings in red.
