A combination of talks and break-out sessions the event was interesting.  The mix of students, academics and professionals meant there were different views on the suitability of crowd-sourced information.  Discussion within my break-out group ranged from how can we verify the crowd to trust the information to how can we incentivize people to provide more structured information.  There was also the typical concern of how can responders know if they can trust information.  This had already been brought up in Michael Goodchild‘s talk “It’s About Time: The Temporal Dimension in VGI,” the idea being having some unverified data is better than having no data.  I think wider acceptance of crowd-sourced information is just a matter of better analysis tools to determine what data is better and encouraging the crowd to submit data so there is more information available.

I gave a talk about the new collaborative analytics tools we’ve been adding to GeoCommons.  Specifically my talk was “Enabling Collaborative Analytics for Faster Answers in a Crisis,” the idea is that the next step in a crisis is enabling the crowd to perform analysis.  Traditionally analysts create reports which then go to decision makers.  If changes need to be made to the end report tasks go back to the analyst.

The next step in analysis is to enable everyone to perform analysis. There are key things that need to happen in a system for this to be effective though. The first is to make analytics easy, this allows the user to make good decisions when they perform their analysis. Within GeoCommons we have aimed to do this and you see results of it through the application, such as when making a thematic map. When deciding on classifications of data we allow the user to match the type of data by matching their histogram versus the available classification schemes.

By making decisions as easy as matching pictures but allowing the user to go into the details it means that both experts and beginners can perform useful analysis. The next steps in encouraging collaborative analytics is making analysis traceable and making results extend-able. That changes the flow of analysis from an analysis making a report to allow analysis to be branched from and putting analysis tools in the hands of decision makers. This eliminates the bottle neck of only have a small group of individuals that can perform analysis and allows for faster response.

One of the most useful references for me in this process was a workshop Tom Carden gave at ETech last year on the data rendering capabilities of a variety of approaches. The readers digest version of the workshop went something along these lines:

HTML/Javascript – handles 100-1000 data points – loads in .1 seconds
Flash – handles up to 10,000 data points – loads in 1 second
Java/Processing – handles up to 100,000 points – loads in 10 seconds
OpenGL – handles upwards of 1,000,000 points – loads in 100 seconds

For Maker we wanted to be able to handle 10,000+ points/polygons and there was no way JavaScript was going to be able to handle it. Of course rendering the data was just one of many problems. Not only did we have to render the data but also parse it from the server out to the client while running the mathematical operation enabling you to take advantage of the structured data being sent. The team came with lots of clever tricks to pull it off, but the level of performance afforded by using Flash for rendering the vector data was not available with JavaScript. Processing could be a very cool option as the technology matures. Silverlight could also be a great option if they can get the plug-in universally embedded into browsers as with Flash.

While Flash was a great option for the tiling and vector rendering we did not want to build out the entire application in Flash for a variety of reasons. In GeoCommons everything outside of the map itself is JavaScript/HTML. This is probably rudimentary for many folks, but reading the debate on James’ blog I think sometimes developers lose sight of picking the best tool for the job. Oftentimes it is easy to get wedded to an approach just because it is what you know well. We were complete Flash rookies when we started, but got some great help from Tom with Modest Maps, Axis Maps with the Flash development and cartography, hired some full time resources, and learned a lot on our own. It ended up being a great approach for the specific problems we were facing. As long as you are using standard interfaces in your development, you should be able to fluidly adapt to the technology that makes the most sense for your set of problems.

Geodata is not available to all – the Farm Bill (H.R. 6126) prevents the FSA from providing geospatial information to the public. Visit Surveying, Mapping and GIS for more details about what Sec. 1619 Information Gathering entails.

Google Maps is still number one. Cowen & Co., an industry analyst firm specializing in covering Web services, found Google Maps as the “de facto leader” in the online mapping solutions space. The analyst firm stated the competitors’ lack of innovation gave Google its success. They also cited Google’s Streetview and public transportation services as main reasons for success.

Geocoding can provide vital information to marketers. Appending demographic census track data to latitude and longitude coordinates is critical for businesses targeting demographics. Many businesses are using Geocoding as a local search tool, a routing tool, and as a store locator.

Florida tries to coordinates a statewide effort for GIS. This is the fourth time the state tried to develop a coordinating body. With the active Atlantic hurricane seasons, and the death of 208 residents, the state realized that coordination of geospatial information during the hurricanes would have saved lives. The Florida Division of Emergency Management (FDEM) is taking the lead in formulating a statewide GIS strategic plan.

Blue Marble Geographics plans to answer the need for highly accurate mapping through their products. After combining their Geographic Calculator and Geographic Transformer into one desktop product, users now have control over the use of geodetic datums to ensure accuracy and coordinate control when transforming geospatial data. The company is expanding their products so surveyors, GIS and engineering firms will be able produce highly accurate maps.

GeoEye-1, the world’s highest resolution commercial satellite , launched this past weekend. The satellite will orbit the Earth’s surface taking pictures exclusively for online mapping. The U.S. Government and Google Maps are some of those planning to use the high-resolution satellite camera.

A new interactive map was developed to show the National Hurricane Center’s latest storm advisories. The StormTracker Map shows current center location and forecasted positions. The map has an easy user-friendly layout and all users need to do is click on their desired location to reveal its information.

ArcGIS 9.3 is receiving applause for its error report system. If a crash occurs, users can send an error report to ESRI. The Geodatabase Development Team even posted a video that talks about how ESRI investigates and acts on all error reports.

ArcGIS Server 9.3 is going mobile. The TD Group announced the release of Freeance™ Mobile 2.0, a new application that incorporates ESRI’s ArcGIS Server 9.3 Postgres database integration for GPS enabled BlackBerry smartphones. Features include GIS searching and database reporting, and linking database records to GIS map features using reports.

After last week’s release of Google’s walking directions, they have decided to simplify the Google Maps layout. Google aims to create a less cluttered look, allowing for a bigger map display and moving the search to the top of the map. The motto for the new layout is: “less is more.”

ESRI posted their results of the 2008 ESRI Q&A. The answers reveal that ESRI will support ‘the ability to check out licenses and borrow licenses from a central license manger for use in that field’ and that they will continue to support Visual Basic for Application in the future. We’ll be attending the ESRI User’s Conference next week, so stay tuned for some feedback from that!

After the release of ArcGIS 9.3 last week, ESRI has now made web help available. The help documentation is apparently very easy to understand. A few of the help features include ArcGIS 9.3. shortcuts, PDF Support and nominal scaling.

As Bill Gates retired, we take a look back at his predictions on mapping. In 1995, Gates said, “You’ll be able to jump into a map so you can navigate down a street or through the rooms of a building.”

EveryBlock, a virtual map that keeps track of news for every city block in Chicago, New York and San Francisco, just added Charlotte and Philadelphia to the list.

ESRI released their downloadable application, ArcGIS Explorer 480, this week. The upgraded version still offers the same basic function of geoprocessing services, but with major improvements such as KML improvements and increase in performance.

Nokia acquired Plazes, an LBS social mapping network. Plazes provides updates of friends’ activities in a find me/follow me type of service. The social mapping application will take Nokia one step closer to “bringing people and places together” and also acknowledges the rise and demand of LBS.

Microsoft and Virtual Earth launched a program that allows state and local governments to share their imagery, called GoVE. All of the imagery from these governments, municipalities and aerial photographers gets sent to Microsoft, which in turn is published by Virtual Earth.
