00:01I think hybrid approaches are exactly the way of the future, and well…
00:08…I'm taking up some time of somebody who I'd rather have talk here, and that's Lauren Bennett…
00:14…and she's going to show you what ArcGIS Online is and define a different way of doing things…
00:21…which is what web GIS is really helping us do. Lauren, do you want to see it?
00:28I'm Lauren Bennett, and I'm a product engineer on the spatial analysis development team.
00:33At this time last year, pretty much all you could do in ArcGIS Online was make a map.
00:38But over the last year, ArcGIS Online has transformed from a mapping application to a true web GIS.
00:46So we'll take a few minutes to explore the power of ArcGIS Online using the example of the Keystone Pipeline Project…
00:53…which is proposed to run from Texas up to the Alberta tar sand and connect with existing pipeline infrastructure.
01:00We want to do this from the point of view of three different users.
01:03The first is a conservation NGO that has a couple of questions.
01:08They want to know if there are critical habitats near the pipeline…
01:11…how many miles of the pipeline will run above the Ogallala Aquifer…
01:16…and the likelihood that a natural disaster like an earthquake might damage the pipeline.
01:21So we'll start with their first question about critical habitat.
01:25We've brought that data in from ArcGIS Online, and to answer this question…
01:29…we'll take advantage of the new ability to perform analysis on the layers in our map.
01:34In this case, we want to summarize nearby the pipeline looking for critical habitat within 25 miles.
01:42Not only do we want to know the total square miles of critical habitat near the pipeline…
01:47…we also want to know the different types of critical habitat that might be impacted.
01:53So we'll run that analysis. It's going to take about 30 seconds.
01:56So to save some time, we'll take a look at an output of that tool…
02:01…and we can see that in the northern section of pipeline…
02:03…we have about 612 square miles of critical habitat that might be impacted…
02:08…and in the southern section, we have another 8.8.
02:11In addition to those totals, we also get information about each different type of critical habitat.
02:17That output is created as a stand-alone table that's supported in ArcGIS Online, and we can take a look at that here.
02:24So one of the critical habitats that stands out is where we have nearly 500 square miles of Topeka Shiner habitat…
02:31…near the pipeline, and that is right about there. So we can take a closer look at that area.
02:38Another reason that we might want to take a closer look at this area is because…
02:41…this is where the pipeline is proposed to run above the Ogallala Aquifer.
02:46We want to know how many miles of pipeline will run above the aquifer, and to do that, we'll perform another analysis.
02:52This time, we want to summarize within the aquifer, looking for the length of the proposed pipeline. Run that analysis.
03:03Now while it's running, we also wanted to take a look at the likelihood that a natural disaster might damage the earthquake…
03:09…might damage the pipeline, maybe an earthquake.
03:12So to do that, to look at that kind of real-time data, we can bring in a GeoRSS feed.
03:17In this case, it's a GeoRSS feed that is hosted by the USGS, and adding it to the map is as simple…
03:24…and copying and pasting the URL and choosing to add the layer to the map.
03:32So we'll take a look at those GeoRSS feeds when they come in.
03:37Looks like we may have been asking too much of the browser.
03:43Downloading a lot of earthquakes from that GeoRSS feed. Okay.
03:48We'll try that again. It's Murphy's Law. Here we go. Reload. It had to happen to someone. That someone is me.
04:18So we'll add that layer again. GeoRSS feed. I'm brave.
04:30And we can take a look at the real-time data right here on the map, very simply.
04:36I also know that that output is going to tell us that we had about 231 miles of pipeline running above the aquifer.
04:44So we're able to answer these very common spatial questions really simply using these simple tools in ArcGIS Online.
04:51The next user is an environmental justice organization that wants to make sure…
04:56…that the pipeline isn't running disproportionately through lower income or disadvantaged communities.
05:02To do that, we have to take a look at some demographics.
05:05We've brought in some demographics from ArcGIS Online. But in this case, we're looking at unemployment.
05:10And to answer our question, we really need to take a look at income.
05:14So all we have to do is change this symbology on this dynamic map service…
05:19…to take a look at median household income instead of unemployment.
05:28And we'll take a look at median household income, and we can do some visual analysis.
05:32We can see the darker areas where we have higher income, the lighter areas where we have lower income.
05:38Now we can do visual analysis, but we want to dig a little bit deeper. We want to take a look at the underlying data.
05:44So we can open up that table, take a look at the raw data, and we can do things like filter.
05:49In this case, we want to see just the census tracks where the median household income is less than $30,000 a year.
05:57We can apply the filter, and we can see where those locations are in relation to the proposed pipeline.
06:04Now at this point, we've done a visual analysis. We've done some tabular analysis.
06:08The last thing we want to do is a statistical spatial analysis.
06:11We want to analyze the patterns of median household income…
06:15…and find statistically significant hot and cold spots of median household income in this area.
06:23While that's running, we can take a look at the output.
06:29The areas in red are statistically significant clusters of high median household income.
06:34The areas in blue are clusters of lower income.
06:37And if we zoom in to the Houston and Port Arthur area where the pipeline will terminate…
06:43…we can see some interesting patterns that we might want to investigate further.
06:47Not only can we create maps and do analysis in ArcGIS Online…
06:51…it's also a powerful platform for sharing and collaborating.
06:55In this case, we've created a group to share our data and our analysis from our Keystone Pipeline assessment.
07:01But this is a pretty sensitive topic and, for that reason, we created this group as a read-only group…
07:07…meaning that only the group administrator is able to contribute content so we ensure…
07:12…that we're providing authoritative data and analysis to the members of our group.
07:17In addition to being able to share maps and apps and data and tools, we can also share nonspatial content like this PDF…
07:25…which is hosted in ArcGIS Online which really is a geospatial content management system…
07:30…allowing us to share our work with a much broader audience.
07:35The last user is a journalist from Lincoln, Nebraska, who wants to visit the five pump stations…
07:42…that run along the proposed pipeline in Nebraska to interview communities and see how they feel about the project.
07:49The first thing we might want to do is plan the trip.
07:52And we can do that using the new ability to get directions right inside of ArcGIS Online.
07:57I can click on each one of these map notes here which I just dropped down on the map.
08:02It's doing that reverse geocoding on the fly. And then we have some more advanced options.
08:10We have the option to optimize the order of those stops, and we can return to Start.
08:16We can run that analysis, and we get our turn-by-turn directions.
08:21We also have the ability to add the route as a layer in our map.
08:26Once that route is a layer in our map, it opens up a lot of other possibilities like performing additional analysis.
08:33In this case, we want to enrich that route with contextual information about the communities that we'll visiting.
08:40We want to get some key demographic facts and also some landscape data within five miles of the route.
08:51And we can take a look at the kind of information that we get when we do that kind of enrichment.
08:55So we get information about land use and land cover, information about population, income, and other demographics.
09:03The last thing that we want to do is share the map. And a great way to do that is as a web application.
09:10Creating a web application is really easy to do using ArcGIS Online because of the apps that come as part of the platform.
09:18One of my favorites is the new story map template…
09:20…which allows you to build a beautiful application using this very simple builder.
09:26And I've already done that, and we can take a look at that.
09:32So I built this app using the builder without writing a single line of code. And it was actually a lot of fun.
09:40You drag and drop the photos. You write the text.
09:42You set the look and the feel of the application, and you're able to share your work with everybody.
09:47So clearly, ArcGIS Online is so much more than a mapping application.
09:52It lets us solve problems. It helps us make more informed decisions…
09:56…and it helps us share our work with the whole world. Thank you.
10:01It's great. Thank you, Lauren. It's fun. Especially the GeoRSS feed that you came back as beautiful.
10:11Yeah, browser problem. Isn't this an amazing platform? I mean, think about that.
10:17The implications of it and now you're all users of it. That's the point.
10:22And when I was behind the stage, somebody sent me a little note says, what about for home use?
10:27Are they also going to get ArcGIS Online? What do you think? We should do that? Okay.
10:34There you go. That's not a joke. That's really what happened. Hey, what Lauren showed was not just content.
10:47She showed a new workflow using online analytics, and this is just beginning.
10:53As the fall release comes, as the next spring release comes…
10:57…there's going to be more and more analytics put into this environment, which, again…
11:01…at this point, you should realize is not just in the cloud. It can also be on premise.
11:08So think about the workflow alteration. Who's going to be using this?
11:14It's a new kind of approach for GIS - interactive, real time, etc.
