00:01And now let's take it one more dimension.
00:03Let's take it to the fourth dimension and bring in the component of time...space and time.
00:09ArcGIS 10 is time aware.
00:12There's all kinds of different time we're going to work with...real time, database time, historical time, decision time.
00:19Many of the problems that we face and we have to solve are space-time problems.
00:24If you want to know when and where pirates are going to attack in the Gulf of Aden, that's a space-time problem.
00:30If you want to understand the migration patterns of caribou in Canada, that's a space-time problem.
00:36Another space-time problem is the Deep Water Horizon oil spill in the Gulf of Mexico.
00:42To tell us a little bit more about this are my colleagues Bronwyn, Nate, and then followed by Undral. Bronwyn.
00:48Thank you, John.
00:50Many of you have seen this map in the news over the past 84 days.
00:55This devastating event happening in the Gulf of Mexico is a space-time problem...
01:00...which we will use to demonstrate that many spatial events contain a component of time.
01:05Just as the world changes over space and time...
01:09...so does the GIS data which we use each and every day to model these real-world relationships.
01:16Zooming in to Orange Beach, we can take a closer look at the boom placement strategy.
01:24Booms are a critical aspect of oil spill response.
01:28They are placed often in coordination with other response techniques...
01:31...like skimmer boats to protect the shoreline and other sensitive areas.
01:36Now, I'm not a boom placement expert, and I'm going to use this application built for the public...
01:44...to investigate the response on this day, June 6th.
01:48I can see that some of my booms are still in the proposal phase...
01:51...while others have been staged and others in yellow have already been deployed.
01:58This boom layer is a time-aware layer, which means that although I can look at it on June 6th...
02:05...far more interesting to me is to navigate through time and see how the response effort has changed...
02:13...new booms are placed, others are removed, and the status is updated.
02:19Now as I was moving through the calendar, there was a lot of activity right around here.
02:25By moving to my satellite imagery, I get a different view of...of...of the area and can see more clearly that in fact...
02:34...all the activity around this big circular boom was to protect these three small islands at the mouth of the channel.
02:42This application designed for the public for people like you and me...
02:45...to investigate the response effort and learn about the incident.
02:50It's also the platform for the emergency operation center...
02:53...to share the most current information available about the response.
02:59Now Nate is going to tell us a little bit more about time-aware layers. Nate.
03:12All of our data like oil trajectory includes a date and a time stamp.
03:18New in ArcGIS 10, we can enable time on this layer.
03:24Like the Web application we saw earlier, Desktop includes a time slider.
03:32This time slider doesn't just work with one layer but all time-aware map layers.
03:37So here we can see the status and location of booms change along with the oil spill plume.
03:47This also applies to imagery.
03:49One of the interesting datasets used to manage this incident is RADARSAT-2 imagery provided by MDA Federal.
03:56Now this is really impressive imagery.
03:58The radar data is actually able to detect the small changes in the gulf wave pattern...
04:04...and can be very useful in identifying the oil spill plume.
04:07So here in yellow we can see the plume pretty clearly. Let's take a look at a couple of other dates...
04:14...the 8th and then again on the 10th; we can see the plume quite clearly here in yellow.
04:21So seeing this imagery in the preview window is interesting.
04:24But what we really want to do is overlay it with the rest of our map layers.
04:31So we see that this dataset is made up of a large collection of imagery, and you'll notice in the attributes that...
04:37when this imagery was collected, it was stamped with an acquisition date.
04:41Using this field, we can enable time on this layer...
04:46...and now we can interact with the collection just like all our other map-aware or time-aware map layers.
05:00Another way to manage a space-time problem is to access real-time feeds in order to perform real-time analysis.
05:12It's so easy to forget just how much activity there is in the gulf.
05:16So from this view we can see oil platforms, wells, oil and gas pipelines...
05:24...as well as the real-time location of vessels and the tracks showing where these vessels have been.
05:30The real-time locations of these vessels are provided by IHS Fairplay's live AIS feed.
05:36Let's check out the Deep Water Horizon incident site and see what's happening there right now.
05:44Well, we can see there's an awful lot of activity today.
05:48We can see our moving vessels symbolized by these arrows and then our stationary vessels here symbolized by our rectangles.
05:55So when managing the repair of this incident site, obviously safety is a big concern.
06:00So what we've done is we've taken the well site, buffered it by 5 nautical miles...
06:04...and now we need to manage this area to ensure safety.
06:07As soon as a vessel enters this area, we need to be notified.
06:11With ArcGIS, we can set up an action or an alert that will highlight any vessels that enter this area.
06:22So here in orange we can see all the vessels that are currently moving in this area.
06:27The action can actually go a step farther and fire off a real-time alert to another Web application or even e-mail.
06:34So if you're not actively monitoring this area, you'll still be instantly notified of any change to its status.
06:40I'm sure we'd all love to see one of the vessels come flying through this area, but keep in mind, this is a real feed...
06:46...and this is, of course, a large area.
06:52So accessing another Web service, SeaWeb, we have access to all sorts of real-time information on any of these vessels.
07:03So here we've identified the A Whale vessel, the oil skimming ship we've all heard about recently in the news.
07:10With SeaWeb, we can see all sorts of information about this vessel but from a situational awareness perspective...
07:17...the last movements and ports visited by this ship are interesting and also very useful.
07:22Now Bronwyn will share another example of how real-time feeds can be used in situational awareness. Bronwyn.
07:31Social media has become a mainstream form of communication between friends...
07:36...from local government to citizens, and even from concerned community groups to government officials.
07:43Turning on my tweets for the past month, I can get an idea of just the sheer magnitude of this spatial resource.
07:54Now this feed is actually already being filtered by the keyword oil spill.
08:01Social media is a new kind of spatial data which us, as GIS people, are probably not that familiar working with.
08:08We don't have full control over the quality of information coming in.
08:13But it does provide us a unique and timely view of what the members of our community are saying right now.
08:20So many of you are probably familiar with Twitter and may even be geotweeting on your smartphones right now.
08:28Ushahiti is another kind of near real-time social network that allows you to post alerts from a simple text message on your mobile phone.
08:38These alerts are verified and then geocoded so we can use them in our spatial applications.
08:46Zooming in to the Gulf of Mexico again, we can turn on our Twitter and Ushahiti feeds...
08:53...which have been filtered by the keyword oil spill and clipped to this region.
08:58First responders can start to take advantage of this information coming from the community...
09:03...to collect data on maybe some stretches of beach that have not yet been...
09:11...stretches of beach that have not yet been cleaned up...
09:13...and we maybe haven't sent our shoreline assessment crews to tackle these areas yet.
09:20So let's filter our Ushahiti feed one more time...
09:26...by the word tar.
09:30What we have here is a collection of four points, all indicating community reports of tarballs on the beach.
09:37Now based on this volunteered geographic information...
09:40I may want to deploy field crews to do that initial assessment and verify these reports from the community.
09:47So what do I need to know at this point? I need to know the current location of my shoreline assessment crews.
09:55In my common operating picture, I have that information right at my fingertips.
10:01My shoreline assessment teams report their current location from a live GPS feed coming from their mobile device.
10:08This information paired with the timely alerts from my community give me the information I need to make decisions...
10:16...to keep the response moving forward, minimizing the impact of oil to people, property...
10:21...and the environment, which is ultimately our goal.
10:27My teams report their current position, but using ArcGIS Mobile...
10:33...we can maintain a log of those positions so in the incident command...
10:37...we know where our assets, our people out in the field have been throughout the day.
10:44So ArcGIS Server really connects our mobile teams with the fields.
10:53Undral is out in the field right now...
10:56...ready to start collecting some new observations using an ArcGIS Mobile project...
11:01...very similar to what hundreds and hundreds of crews are using right now in the Gulf of Mexico.
11:08Teams from the Louisiana National Guard, the U.S. and Florida Fish and Wildlife...
11:14...the U.S. Coast Guard, and a collection of other agencies...
11:17...are working day in and day out to build an inventory of assessment and perform vital cleanup operations.
11:26With the implementation of the ArcGIS system, we have been able to...
11:31...we have been able to collect new observations and rapidly post those back into the enterprise...
11:38...so at the emergency operation center, our...
11:42...our decision makers have all the information they need about the current situation in the field to make better choices.
11:52We'd like to leave you with one last thought.
11:55If you are tasked with managing an emergency response...
12:00...you will be faced with a space-time problem, whether it be a flood, an earthquake, or even a man-made disaster.
12:09Part of managing an emergency response is making difficult decisions about resource allocations...
12:15...decisions that inevitably will be questioned by lawyers, the media, or even the community at large.
12:22You can do some simple things to help...to help validate these decisions...
12:30...things like printing the date on your map, printing the date for which your data is valid...
12:38...and identifying some time-aware attributes for dates of significant change to your features.
12:45For example, a date a boom was staged and then deployed, inspected, and ultimately removed.
12:56By taking advantage of the new time-aware functionality in ArcGIS 10...
13:00...we hope you will be more prepared than ever to manage your space and time problems.
13:04Thank you. John.
13:10Thank you Bronwyn, Nate, and Undral.
13:15In conclusion, on behalf of all my colleagues at Esri, I want to say thank you.
13:21On behalf of an incredible software development team that's built ArcGIS 10, listening to your needs, your ideas, and vision...
13:30...I want to say thank you.
13:32Up next, the 2010 President's Award presentation. Please welcome once again, Jack.
