Package and share the map
1 Zoom to the full extent, and then save the project by clicking the Save button in the upper-left corner of the window.
2 On the Share tab, in the Package group, click the Map button .TIP If you have other project elements you want to share—such as styles, toolboxes, task lists, or attachments—sharing a project package, which includes these other elements, is more appropriate. (You will learn more about styles, toolboxes, and task lists in subsequent chapters.) In this case, sharing a map package is the best choice.
3 In the Package Map pane, maintain the default parameters, and then click Analyze. When Analysis is complete, click Package.
TIP To package a map, there must be a description in the map’s metadata. (To access the metadata, in the Contents pane, right-click the map title, click Properties, and go to the Metadata tab.) There must also be a summary and tags (keywords for searching), which are read from the metadata; if the summary and tags are not in the metadata, you may enter them in the Package Map pane.
On your own
Go to www.arcgis.com and sign in to your account. Click Content and then find the map package under My Content. Click the map and share it with any group or individual you want.

Exercise 2cExperience 3D GIS
Estimated time to complete: 20 minutes
Presenting a 3D map engages your audience and provides a wow factor that your 2D maps may lack. But it is not just about looks—with the power of 3D GIS, you can visualize and modify skylines, experience realistic topography, and perform 3D analysis. For example, you can construct sightlines in hilly terrain. In this exercise, you will learn how to convert a 2D map to 3D.
Exercise workflow
Start a new project, and add a layer of polygons that represents buildings in New York City.
Use the Bookmark tool.
Convert a 2D map to a 3D map, and then extrude features based on the building height attribute to visualize buildings in a more realistic perspective.
Start a new project
First, you will start a local scene project.
1 In ArcGIS Pro, if you are starting from an existing project, click the New button at the top left of the window. If you are starting a new ArcGIS Pro session, choose the Local Scene template.
2 Name the project 3D, and store it in the EsriPress\GTKAGPro\3D folder. Clear the option to create a new folder for this project, because a folder is provided for you.
3 In the 3D project, on the Insert tab, click the New Map down arrow, and click New Map.
TIP ArcGIS Pro modifies the New Map default icon to reflect your previous choice, so sometimes you will click only the icon.
Add data and create a bookmark
Next, you will add a shapefile of some buildings in New York City.
1 In the Catalog pane, expand Folders, and then expand 3D. The project automatically stores a folder connection to the location in which you saved your project.You may also see an Import Log folder in your project workspace.TIP To create additional folder connections, right-click Folders and click Add Folder Connection.Notice that the 3D folder contains a geodatabase and a toolbox, both of which are currently empty and were created automatically when you created the project. (You will learn more about what these things are in subsequent chapters.) The folder also contains a GIS data file named buildings.shp, which was already there.
2 In the Catalog pane, click to highlight buildings.shp, and then drag and release it in the map view.Building footprints that span 10 blocks of New York City’s Upper West Side neighborhood are added to the map, and the map display zooms to the extent of the new layer. Colors will vary, because colors are applied randomly when data is added to a map.TIP When data resides in the project folder, it may be the easiest place from which to drag data to the map, as you did here. If the data resides elsewhere, either create a new folder connection or use the Add Data button , navigate to the desired dataset, and click Select. Notice that you can configure the Add Data button to add different types of data (for example, route events or address layers) by clicking the down arrow.Next, you will create a bookmark of the buildings layer extent.
3 On the Map tab, in the Navigate group, click the Bookmarks button, and click New Bookmark. Name it UWS Buildings, enter a brief description of your choosing, and then click OK.
Create a 3D scene
Now you will convert a 2D map into a 3D scene (without losing your 2D map) so that you can visualize the heights of the buildings in the map. ArcGIS Pro basemaps can be used for both 2D and 3D maps. You can turn your buildings layer into a 3D layer because it includes a roof height attribute, measured in feet.
1 In the Contents pane, right-click Buildings, and click Attribute Table. Scroll to the last column, and sort the Height attribute in descending order.What is the height of the tallest building in this layer?
2 Close the attribute table.
3 On the View tab, click the Convert down arrow, and choose To Local Scene.When the conversion is complete, a new 3D scene is added to the project. Now you will enable 3D rendering for buildings.
4 In the Contents pane, drag buildings to 3D Layers, and then release.
5 In the Contents pane, right-click the buildings layer, and click Zoom To Layer. Do not worry if the buildings do not render correctly in the 3D map—they must be extruded before they can be displayed properly. Extrusion is the process of stretching flat 2D features vertically so that they appear three-dimensional. You will extrude the buildings based on the building height attribute field.
6 With buildings selected in the Contents pane, on the Feature Layer ribbon click the Appearance tab. In the Extrusion СКАЧАТЬ
