ArcGIS Pro supports the creation of both global and local 3d scenes. Viewing worldwide data on a globe allows the viewer to spin a virtual model of the planet around to explore relationships across the planet.

- [Narrator] All of the maps that we've looked at so far were two-dimensional flat maps like the ones you would create with ArcMap. ArcGIS Pro also supports the creation of both global and local 3D scenes, something that previously would have required an entirely different application such as ArcGlobe or ArcScene. Because they all live within the same project file, you can create multiple views of your area of focus in order to craft the best story possible and show your data in the most engaging way. Let's start taking a look at this by adding a 3D globe view to our world map. To do that, we'll visit the insert tab on the ribbon.
Then we'll click on the bottom portion of the new map button and come down to new scene. That adds a global scene to the project and opens up a new view. You can view the new scene in the maps folder of the project pane by expanding the folder and we can see it right here. Just like with 2D maps, you can right click on it and rename it. I'll go ahead and call this globe. We can also change the base map that's being displayed by visiting the map tab of the ribbon and then coming over to the base map gallery. I'll go ahead and choose the ocean base map. With the explore tool on the navigate portion of the map tab active, you can go ahead and click and drag on the globe in order to spin it around.
You can also use the scroll wheel on your mouse to zoom in or zoom out of the globe. We can also use the same keyboard shortcuts for navigating the 2D map here in three dimensions. Plus and minus will zoom in and out of your map. The left and right angle brackets will move back and forth between the previous extent and the next extent. And if your globe gets a little bit wonky like mine is right now, you can tap the N key to orient north up. Many of the techniques that we explored with our 2D maps also apply directly to the 3D environment. Data layers and symbology are added and altered in exactly the same manner.
Let's go ahead and add some data to our globe. Inside of the databases folder for the project, we'll find our world data geo database and I'm going to drag the populated places feature class and drop it into the map. Notice that it gets added in to the 2D layer section. We could move this data into three dimensions by extruding it into a volume by referencing one of the attributes. In other words, we could take the circles that are on the map and convert them into cylinders. With the populated places layer selected in the contents pane, I'll come up to the appearance tab. Then we have a new section here called extrusion.
This first button here called type will allow us to control how we extrude our cylinders. The first option is the one we're currently on and that's none or to have no extrusion. We're just viewing the individual points on the map. Base height will add extrusion to each vertex in the shape. Since we're working with the single point data, the last option is actually the one that we want though, to simply extrude the features up to a flat top. Go ahead and choose the absolute height. Then in the next drop down box to the right, we get to define which attribute we want to focus on. In this case, I want to extrude cylinders that reference the population of each populated place.
I'll choose the pop_max attribute. Then I'll change the unit from meters to feet. This will map the population value in the attribute table to a dimension that can be viewed in three dimensional space. Now we can spin around the globe and we can see the relative differences of different populated places around the globe. I'll go ahead and tap the N key to orient north up again and focus on North America. To add another visual cue, we can also apply the same graduated color symbology to the population values. This time, I'll click on the symbology button in the appearance tab. That'll open the symbology pane on the right side of the interface.
I'll change it from single symbol to graduated colors. Then for the field, I'll change it from scale rank to pop_max so that we're viewing two different attributes of the same data value. Now we can visualize the most populous cities based on the color and length of the column on the globe. This is just one example and there's lots of different ways that adding a third dimension can aid in the exploration of your data sources. Extruding data onto the global scene can make for some compelling visualizations and help you gain insight into the state of the planet.
