00:01While Mary was looking back at the existing conditions and asking why things were...

00:06...our next presentation looks forward to plan what could be.

00:11So please welcome from the City and County of Honolulu, Mayor Peter Carlisle and Ken Schmidt.

00:22On behalf of the nearly one million residents of Honolulu, Hawaii, I bid the 15,000 of you here today a warm aloha.

00:37Aloha.

00:39Oh, you can do better than that. Let's try it again. Aloha, I can't hear you.

00:43Aloha.

00:45Outstanding. Thank you.

00:48[Inaudible]. Honolulu is a unique island community anchored in the middle of the vast Pacific Ocean.

00:56Can you hear me now? Hey!

01:02In our city, you can surf in the morning as the sun rises over Diamond Head.

01:08There is a family culture and family living arrangements; the Hawaiian call family the word ohana.

01:16For decades, we have had a proud history of using GIS to manage our city.

01:22Today, we face the challenge of urban sprawl and extreme traffic congestion.

01:29Honolulu has the dubious distinction of having the worst traffic of any city in the United States of America...

01:38...even beating your northern neighbor, Los Angeles.

01:43To help complete Honolulu's elevated transit system, which is currently under instruction [sic]...

01:49...I reached to our GIS program to visualize how transit-oriented development will benefit all citizens of Honolulu.

01:59Ken Schmidt, our GIS administrator, is here to show us potential scenarios of transit-oriented developments...

02:07...in contrast to doing absolutely nothing.

02:12Thank you, Mr. Mayor.

02:14Thank you, Mr. Mayor.

02:16To understand how transit-oriented development will impact our island communities...

02:20...we worked with local planning professionals to evaluate possible impacts of different design scenarios.

02:27Using the latest geospatial technologies, we're presenting these alternatives to the stakeholders in our communities.

02:34Helping me with the demo today is Michael Contreras of Esri.

02:38Nice aloha shirt, Michael.

02:43Here we can see the island of Oahu with streets and building footprints.

02:46This shows how the linear concentration of the island is along the southern side.

02:52The planned route of the new transit system follows this pattern.

02:56A major factor in planning TOD communities is creating walkable, friendly zones.

03:01We derive the walkability or travel distances from each station to the surrounding area.

03:07This lets us know how many people would consider themselves within walking or cycling distance of each station...

03:12...and how many would consider themselves too far away.

03:17This is crucial for understanding how effective the development will be.

03:22And this is true even for those communities that don't exist, such as the last three stops on the far west end of the route...

03:29...an area of former sugarcane land that is ripe for development that we call Ewa.

03:35To begin our planning, we must first create a model of the physical environment for the entire transit system corridor.

03:43This gives us visualization scenes that are familiar to our stakeholders.

03:48Here is an aerial image showing the downtown district right along the waterfront to Honolulu Harbor.

03:54We can visualize this urban environment using our existing data, which includes 3D geometries...

04:02...produced by the Precision Lightworks products.

04:06As we surf our way to the Honolulu business district, we see that our texture models include many key landmark buildings.

04:14But like many 3D models, we also have a lot of buildings that are not textured.

04:20In fact, we have 3,000 building geometries that are currently blank canvases.

04:26So to improve upon these buildings, we're using a CityEngine rule to paint representative features...

04:32...onto the geometries based on the usage type of each of these buildings.

04:38Adding textures onto the models is as simple as flipping a switch.

04:43So it's effectively painting our blank buildings as you watch.

04:49The software came with a number of sample images for doing this, but we wanted to use real photos taken in Honolulu.

04:57So with some help of some very willing volunteers who wanted to get out of the office...

05:02...and go out on their mopeds on a beautiful day in Honolulu...

05:06...they went and took some pictures of local buildings to get Honolulu building facades.

05:12So now, we have nice buildings for a large section of the city.

05:17But we have more buildings that are only available with building footprints.

05:24So the rules can also generate geometries, and we convert our footprints into complex 3D shapes...

05:32...and apply textures to complete our 3D building model.

05:37There we go, our urban Honolulu.

05:42Buildings are not the only data we need.

05:44We also needed to generate our elevated transit line.

05:47Using engineering drawings, we did so.

05:53Generating all the 3D data we needed for this project was simple.

05:57We just leveraged the data we already had.

06:10Because each of the transit stations will have a unique impact on the surrounding neighborhoods...

06:16...let's take a closer look at the Kalihi station.

06:20It will be vital that local residents have a livable, vibrant community around these stations...

06:26...and for Kalihi, we actually needed to rezone that area to make that happen.

06:31So here's one proposal for that rezoning shown in the traditional way of colored polygons.

06:38But we can do more than simple thematic display that relies on a legend.

06:43We can create building envelopes directly from the zoning rules...

06:47...and we can even generate example buildings that could be built inside these envelopes.

06:53And for anybody who's done permitting, this is a major achievement for us.

06:59Of course, this is just one possible scenario, and there's no guarantee that this is the best one.

07:05In fact, a key principle of geodesign is to iteratively come up with alternative designs and to present them to the community.

07:15Here are the potential buildings for a second development scenario.

07:20All these buildings were generated based on proposed plans using different design standards...

07:25...such as floor area ratio and open-space requirements.

07:30And if the community doesn't like the rules, which isn't unusual, we can change them.

07:37We can even manually design a new building from scratch, and we can do this by simply deleting the generated model...

07:44...and using CityEngine's new 3D model editing tool, interactively sketch in a new one.

07:51For example, a challenge in Hawaii is that buildings need to fit into the existing Hawaiian architecture...

07:58...so a neighborhood's fish market isn't just a generic grocery store.

08:02I can't remember how many public meetings that we've been to where someone has put up their hand and said...

08:07..."I don't like that building."

08:10But now we have the ability to quickly and easily modify the design and say, Alright, how about this one?

08:18Our ability to generate both existing and real-world buildings and potential buildings based on zoning data and edit functions...

08:28...is making it incredibly easy for us to plan and validate different designs for this project.

08:36It is also important to make decisions at the macro scale, and one of the primary goals of the elevated rail transit project...

08:43...is to reduce evil urban sprawl.

08:46By the year 2050, another 140,000 housing units will be required on Oahu.

08:54By analyzing influences such as terrain, slope, and proximity to existing streets, we generated a predictive surface...

09:02...where urban sprawl will appear in currently undeveloped spaces along the transit area.

09:10This clearly shows that the west end of the rail contains some very attractive land for new development.

09:17If we take a closer look at the community of Waipahu, the green area shows where the new housing is likely to be developed...

09:24...but how much and when?

09:27We developed an urban growth analysis to answer that question and then ran it based on the proposed TOD plans...

09:34...that includes urban densification around each station.

09:39The result - the dark blue areas are likely to be filled in over the next 40 years.

09:46But what if we don't build the new rail line?

09:50We simply rerun our analysis, this time based on the current zoning plan, and what is revealed is a very different future.

10:00This is what will happen if we do nothing.

10:03Pretty scary.

10:05More urban sprawl, greater transportation costs, and a less sustainable future.

10:12Of course, having all this great GIS content and knowledge means nothing if we can't share it...

10:17...especially given that we need the public backing to make the elevated rail transit line happen.

10:24We can upload our 3D scenes to the web to connect us directly with the public in a medium that is interesting and engaging.

10:33This is the same urban growth data for Waipahu that we saw in ArcMap but presented in a more human way...

10:40...with actual buildings showing the alternate futures.

10:43This is the current state of Waipahu, a former sugar plantation community.

10:50This is the future of Waipahu if we build the rail.

10:59But this is the state of Waipahu if we continue on the current path, no transit system being built.

11:10Visually, this says it all.

11:13Thank you.

11:20Now the mayor of Honolulu wants to show you another way we are communicating these alternatives to the community.

11:26Can you hear me now?

11:29You know, I was in the back with Jack Dangermond, and I said, I'm amazed that the technology's working so well.

11:37I jinxed myself.

11:40GIS is a bridge to the future.

11:44To further engage the public, we partnered with Zebra Imaging to produce holograms.

11:51Here in front of the stage is a hologram of the Honolulu rail system through the downtown portion of the urban core.

12:00We are now in a tough political battle to determine if the rail system will be completed.

12:07The use of the hologram emphasizes the flexibility that exists for future transit-oriented development.

12:17Rail and TOD, transit-oriented development, will provide the spinal column for sustainable transportation...

12:24...long-term job growth, a greener future, and smart land use that will last for a century to come.

12:32For having us here today, I'd like to say Mahalo nui loa, which means thank you very much.

12:41Thank you. Thank you, Mr. Mayor.

12:47It's good to see you, my friend. Thank you.

12:49It's really a pleasure.

12:51You're pioneering. I don't know if you know this, but you are pioneering something.

12:55That's exciting. It's the whole world of geodesign.

12:59What do you think, Carl? Are you out there?

13:01What do you think? Pretty good, huh?

13:04It's damn good.

13:05It's damn good.

13:07Thank you, Carl.

13:08He was my professor and the...well, to acknowledge this, we're going to give you something called a Making a Difference Award.

13:17Thank you.

13:18To you and also to your staff, this is great. For me, wonderful, isn't it?

13:25This is a huge honor. I'm humbled, and thank you very much.

13:28Thank you. Thank you, Peter. Good luck.

13:32Aloha.

13:36Thank you, Ken. Thank you, Mr. Mayor. Thank you, Jack.

13:41All the presentations that you've seen this morning are using the ArcGIS 10.1 release.

13:47The tools that you have today, except for what you just saw.

13:52That was using the new CityEngine 2012 release, which is still in beta but will ship September 12th.

13:59So I just wanted to reinforce that message that this morning what you're seeing are the tools...

14:04...and the capabilities that you have in your hands.
