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?

00:25Thanks, Jack.

00:26Thank you.

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.
