00:01What I want to do is tell you a little story.
00:03Doing a little bit of geodesign but doing it in 3D.
00:07So what we're looking at here is the city of Philadelphia.
00:10Everyone thinks to the city of Philadelphia and Pictometry for the data, but this the area known as Logan Circle.
00:18It's kind of defined on the boundaries by the Franklin Institute, the Moore College of Art, the library.
00:24You actually, many of you probably know this site.
00:27You've seen it because probably most of you have seen Rocky.
00:32And this is where he ran up the steps and holds his arms up, right.
00:34So that's kind of, we're going to pretend that that's a historical moment that we want to preserve that skyline...
00:43...for history when we're doing our design.
00:47So here we see we're looking at that perspective as if you are Sylvester Stallone and you can see there's...
00:52...a red line that defines what makes up that skyline.
00:56And that's actually a tool we've developed, a new tool at 10.
01:01What it's actually doing is reaching out into the distance and finding each feature that defines that skyline...
01:08......and we create this kind of, this network, that you can turn into a shell.
01:12And that shell represents...if anything violates that shell, then we know that it's destroying that skyline.
01:18We're going to use that a little later on to evaluate our designs and see whether we're actually affecting the skyline.
01:26So, as I mentioned, we've got this area here around Logan Circle.
01:31What we want to do is, we want to do a redevelopment plan for this study area.
01:35We think it's underutilized, we think we could make some changes and improve it.
01:40Basically improve its commercial potential and add some more residential into the area.
01:46So what we're looking at here is a couple pieces of data.
01:50We're looking at land-use data, the red is existing commercial, the orange is residential...
01:54...the green is parks and open space, the purple is institutional.
01:57On top of that we have parcel availability.
02:00The dark yellow parcels are abandoned, the light yellow parcels are ones that we've identified that we want to redevelop.
02:08So, and we also have a small section of light rail that comes in on the bottom left corner there, you can see.
02:14So what we want to do is take those and overlay those.
02:17Classic GIS and do a suitability analysis to see what our redevelopment potential is in this area.
02:23So we're just going to use a geoprocessing model to kind of flatten them and munge them together.
02:28So we can see on the bottom left side here.
02:31In green and blue, the areas that have higher economic redevelopment potential.
02:34I realize there's not a lot.
02:36There's not a lot we can do here.
02:38It's pretty well built to what it currently has in terms of amenities.
02:42What we want to do is, we want to add to this a new light rail system to try and promote some economic development.
02:49So we're just going to go in and quickly sketch in a some sort of light rail system and do...
02:55...redo that redevelopment analysis and see how that's impacted our redevelopment potential in the area.
03:03So this is a rough route of a light rail system.
03:07So we can see in the bottom right there is ModelBuilder running. That's a way that we use to string...
03:12...different geoprocessing tasks together, and then you see a revised economic development...
03:17...redevelopment potential and we've got a lot more blue areas, and we can actually summarize those.
03:22Alright. But looking at it, we still didn't get much on the north.
03:26We still didn't get much on the top, we want to make some changes.
03:30So we're going to resketch that line to try and cover that northern area better and then rerun that analysis...
03:39...to see how that's impacted our redevelopment potential.
03:43See here, we rerun the analysis.
03:52Takes a second, of course.
03:54And then we can look at the summary of how that's impacted and what we're looking at here is actually...
04:01...the little skinny bars on the left are what we had and the thicker ones on the right are what we have now.
04:06So this is this concept that we can keep, as we do design, we can keep doing the analysis.
04:11We can use analysis to inform design.
04:13We can do multiple scenarios. We can try different things. It's this idea that Tim Brown from IDEO touched on.
04:19It's that we learn with our hands, we learn by playing and doing and trying and then evaluating while we do it.
04:27So we've decided that this is, this is kind of the rough configuration of what we want to add to this urban area.
04:33Next thing we want to do is kind of make some decisions about where we want to place these, our buildings...
04:37...new buildings we're going to put in this development.
04:40So what I have is, I have a template of, just to build simple buildings, massing models at different heights, different sizes.
04:47I'm going to go in and in the areas of high redevelopment potential place those massing models.
04:53Now what I want to do is I want to go back and take those massing models and compare them against that...
04:58...critical skyline that we developed and see make sure that they don't extrude beyond that...
05:04...that they don't violate the skyline that we're trying to protect before we go any further.
05:10The next question I want to ask, though, is what type of transportation system am I going to put in.
05:15...that does some data management for us.
05:16Am I going to put in an elevated or a subway?
05:19So here what I did is, I just tilted and I looked underground, and I'm looking at soils underground.
05:24These are kind of a voxel representation of soils 250 meter x,y, half-meter intervals.
05:32What we're going to do is, we're going to take this proposed route, turn it into a subway tube...
05:38...submerge it underground, intersect it with those soils and figure out what we would be excavating in terms of...
05:45...in terms of volume and the types of soils we'd be excavating to see how much that would cost.
05:50So we can kind of see the tube with soils we're going to fly up.
05:53We're going to look inside that tube, kind of look around the corner, see composes the outside.
05:59Maybe because of this we decide, no, we really don't want to do anything subservice...
06:03...we don't want to do the subway, we want to do an elevated system instead.
06:08So, we've decided to do an elevated, what we have is we have a little geoprocessing model...
06:17One, it takes that route, creates an elevated system out of it.
06:21Second thing is it takes all the existing buildings and fills them in around our proposed buildings.
06:28Third thing it does is takes those proposed buildings and splits them into floors and spaces.
06:33And we're going to use those floors and spaces to do analysis inside the building on where...
06:38...we should place different types of land use at the floor, at the suite scale.
06:43So first thing we do is...now we're going to look at that raised, elevated route, and we put stations and stops along that route.
06:50And those stations and stops affect what we decide to put inside those buildings.
06:55So we have a suitability model here that looks at retail suitability and allows you to assess the space inside...
07:01...based on how closely they are to those stops and what kind of connectivity they have with those stops.
07:06So we run that model and we can see now, highlighted in the darker reds, areas that have higher suitability...
07:13...for retail or commercial development in 3D, right?
07:16And it's pretty localized and it's 3D because you have connectivity between the stations and stops differently...
07:23...with the surrounding buildings.
07:25You might have connectivity on the first, second, or third floor for a stop...
07:28...or just on the third floor for a station, right?
07:31So now we actually want to start carving into those buildings and start defining the spaces inside those buildings.
07:37So against our editing, I have template of different types of land uses I can find in my building and I put a retail outlet there.
07:44You put retail outlets across my whole development.
07:46They're one of the things that is key for when I start deciding where I want to put my residential.
07:51'Cause we want to put residential people close to amenities so they have some place to shop...
07:55...when they're looking for groceries or other items.
07:58The second issue of concern is for residential, is we're concerned about the quality of views.
08:04So what we have here is we have five red dots.
08:06These red dots represent attractive views in the city of Philadelphia.
08:10We've got the Logan Circle itself, the archdiocese, the Franklin Institute, and a couple parks.
08:15And what we want to do is assess which spaces in those kind of proposed simple building...
08:19...massing models can see those really attractive views.
08:24So we've got a model that connects those with lines...
08:27...does a line-of-sight analysis and figures out how many attractive views each space could see.
08:33And you could do this with attractive views or you could do it the other way, you could have things...
08:36...you don't want to see, and see how many unattractive views you could have.
08:40So here you can kind of see that diagram connecting the views back into that spaces in the buildings.
08:47The darker green spaces have more views or higher quality of views.
08:51So we have this little building in the background here.
08:53It's a four-story building, we really wanted to put some residential inside that building, but it doesn't have any views.
08:59We've made a decision we want to make it taller.
09:01We want to actually have some residential in those top floors of this building.
09:04So we just go in, we select that building, we delete it.
09:07We're going to sketch in a new building massing model around it that's 10 stories tall.
09:14And then we're going to use the data management tools that we had to, again, split those into those kind of...
09:19...theoretical floors and spaces I was talking about earlier.
09:23Here's the data management model.
09:27This is one building. It runs faster.
09:29Pull the exterior off, you can see those spaces, we rerun that line of sight model.
09:32Here's the line of sight model.
09:34I know it looks kind of big and complex. It's really not that scary.
09:41Do that line-of-sight analysis, and then we can see the spaces inside the floors, darker green, lighter green...
09:46...depending on the quality of the views.
09:49So now we want to combine the view quality, the proximity to those retail outlets, to do residential suitability...
09:56...inside buildings, and then we're going to carve it, go back inside the buildings and start defining...
10:00...spaces inside the buildings.
10:02So here, I'm drilling down back to the first floor.
10:04I'm going to start sketching out what I want to put inside this building.
10:07It's next to a station, so I want to put commercial on the first floor.
10:11We've got an off-street parking requirement, so we can't...
10:17On the second floor, we want to put another commercial space right next to a station where there's connectivity.
10:22On the opposite side where there's low-quality views, we're going to put in office space.
10:27We have an off-street parking requirement, you can't negatively impact the streets, we can't just force everybody...
10:33...to park on the street, so we're going to actually have a parking structure and a ramp for people to get up.
10:40And then above that, we're going to go ahead and place some residential areas.
10:44You can see, we're starting near the parts that have higher-quality views on one side of the building.
10:48So again, I sketch in a residential area on the third floor, and I can duplicate that to the fifth and the sixth floor.
10:56So this is the same concept we've seen before except now we're sketching in 3D, and we're planning...
11:03...a land use in 3D kind of at the building or the suite scale.
11:09And we can do that across our whole area, create all the spaces.
11:12Now we want to take these kind of simple massing models that we have, which are ugly gray blocks...
11:18...and we want to improve them.
11:20So in this case we're going to export this gray block out to COLLADA.
11:23We're going to bring it in to SketchUp, which is kind of the more common tool for doing attractive exterior work.
11:29And then we're going to use that SketchUp model once we've enhanced it to replace the gray block...
11:34...to get a more attractive building exterior.
11:36So here, we see the kind of more attractive exterior.
11:39And all these features are created in GIS, right, so they all have attributes.
11:43So at the end, we can do summaries and see how much of each land-use type we created in 3D...
11:49...and see if we actually met the goals of our program.
11:52So I'm not saying that this is how you would do a 3D, this is some of the tools that we have available now that you...
11:58...can use and mix with the other existing GIS tools.
