00:01The thing I like about CommunityViz, it's software for planners.
00:03It's built as an ArcGIS extension and it's been around promoting informed collaborative decisions…
00:10…in the sort of public planning arena since 2001.
00:13It's built by our company, Placeways, in partnership with the Orton Family Foundation…
00:18…and Esri's been a great partner all the way through the years.
00:22Thank you very much folks for the nice award they gave us last year.
00:26On the other hand, I hate going right after these guys, 'cause we're always working on what they built…
00:32…and demoed a year ago, so we always look like a year out of date.
00:35But I loved what I'm seeing coming next, and if you come here next year, I'll show you what we're doing with that.
00:43Obviously what I want to emphasize today is CommunityViz as a geodesign tool for planners.
00:49And my main themes are geospatial analysis, which is so, so wonderful…
00:56…flexibility, and accessibility. CommunityViz is meant to be widely used. It is…it's not expensive.
01:04It's used by governments and people in all 50 states, 40 countries around the world.
01:09Last year the American Planning Association published a book about it.
01:15So what I thought I'd do is just show a few examples. I'll start with sort of a classic GIS example of suitability analysis.
01:24Ours is just a little different. This starts with a park placement.
01:27This is in downtown Boston, and with CommunityViz you can pick any factories you want.
01:35If you have data about where schools are or where parks are, you can include that in your analysis.
01:42We actually do our math in vector rather than raster, which has some advantages for us.
01:47And when you do it, you've got a map; the darker colors mean a better place for a park…
01:51…but then you can adjust the weighting factors on each factor and get new results, all in practically real time.
01:59It's a little update that happens but it's fast and you get new results.
02:03Another thing we see in sort of real-world planning is just a lot of informal data.
02:08So for instance, if you go into Boston, you say, We're going to put a park, they say…
02:11…Whatever you do don't put it on the boundary of the turf between two gangs. That's not a safe part of the city.
02:18So, you say, Well, where is that boundary? And they'll draw it for you and you can have a discussion…
02:22…about how close you should be to the boundary, again in real time, what is safe.
02:27Somebody else may say, Wait. That line's in the wrong place. I want to edit it. I want to adjust it.
02:32And this is geodesign. You edit, you adjust it, and in real time you get new results. So, that's one example.
02:43Next, I wanted to go a little bit into the formulas that CommunityViz uses. We have a way of doing calculations.
02:51It's kind of like ModelBuilder, looks a little bit like Excel, looks a little bit like Python…
02:56…but what it allows us to do is create a huge number of impact calculations.
03:01So, here for example, we were calculating the impact of some redevelopment.
03:04One of those many, many impacts was schoolchildren that would be generated put into the community schools.
03:11If you want to see how we got that, you can. In about three clicks you can drill down and look at the formula that's being used.
03:18Again, these formulas may look a little foreign when you first look at them but they're not hard and they're very powerful.
03:25They are full of different functions that are geospatial functions, statistical functions, text functions…
03:31…that allow you to create kind of any model that you can imagine writing a formula for pretty easily and pretty quickly.
03:38So you can take these formulas, you can edit them, you can share them with your friends…
03:42…you can make up new ones, or you can let the computer build them for you.
03:46Nevertheless, if you feel like all that formula writing is too scary, you may just want to use a wizard.
03:53And CommunityViz, over time, has built a lot of wizards that make this stuff really easy…
03:57…even for people who aren't that technically inclined.
04:00So, here this is a very flexible wizard. A new question comes up. Where exactly are those schoolchildren going to go?
04:08Which schools in the community? And within a few clicks, you can create that new analysis.
04:14You don't have to do a new module. You can create it yourself and in very little time it'll make all the formulas for you.
04:21It'll make you a nice chart and it'll solve that problem as it arises as part of your conversation…
04:27…which is getting to the invisibility point.
04:31Finally, I want to talk about table-top sketching. This next drawing I'm going to show is at a different scale.
04:36It's at a regional scale and it…it's made to be used in a table-top environment.
04:43This one we did with Texas A&M down in the Houston/Galveston area.
04:47So this is now a huge region, I don't know how many hectares, but it's a lot.
04:51And the idea here, you've all seen this, you pick a place on the map, you select it, and you say…
04:56…I want this to be a commercial park and you click on it; all the impacts that go with that get updated right then.
05:07So you learn about social impacts, you learn about economic impacts, you learn about environment impacts…
05:13…through some simple and some perhaps very sophisticated models, but it's presented in a nice, consistent way.
05:21This is construction tools. This is a painter tool.
05:25There's actually lots of different ways we try and give people to work with the map…
05:29…whether it's selecting, or painting, or cloning. All of those, a lot of which we've seen this morning, are helpful for us.
05:36If you want, you can look at a couple of different scenarios side by side, or five or six…
05:42…and talk about different ways to treating a particular place on the landscape.
05:45What benefits or disbenefits that may have.
05:49If you want, you can drill down much more deeply on any particular result.
05:54So here, it's just a hurricane-prone area, so construction…hurricane-proof construction and damage is important…
06:03…and you can adjust the inputs that go into that, find out a lot more about it if that becomes a topic of particular interest.
06:10Even more interesting is the hurricanes themselves, and in this particular example we connected to SLOSH…
06:16…and actually I got some historic hurricane paths, so people had their nice plans laid out…
06:22…and then we let them put a hurricane across it and see how many houses would flood and what kind of damage it might sustain.
06:30Sort of high-impact scenario planning I guess you could say.
06:36So the point about invisibility is, all of this technology doesn't really matter in a public planning environment.
06:43Nobody really cares whether you have the greatest, coolest new button.
06:46What people care about is, Can they make good decisions?
06:50So this kind of application comes together in environments like this.
06:55This is people standing around a table having a conversation person to person about different plans.
07:02And this is different stakeholders, different points of view, but they're working together as people…
07:07…with the information they need literally at their fingertips.
07:10And after about 5 or 10 minutes, if we're doing this right, they stop thinking about how cool this technology is…
07:16…and they start thinking about the plans they actually want to make.
07:20And that, I think, is a goal we should all have, is making geodesign invisible…
07:27…making people visible, let us make better decisions together.
