the problem, therefore, is an ongoing process, one that will occupy you throughout much of the book.
Exercise 1a: Explore the study area
In this exercise, you’ll get to know the Los Angeles River and its surrounding area with maps and data. At the same time, you’ll learn the basics of working with ArcGIS Pro: how to navigate a map, add and symbolize data, and get information about map features.
Start ArcGIS Pro
Now you’ll open the ArcGIS Pro application.
1)Start ArcGIS Pro by clicking the Start button on the taskbar, and then, on the Start menu, click All Programs > ArcGIS > ArcGIS Pro > ArcGIS Pro.
To open ArcGIS Pro, you must sign in to ArcGISSM Online using an organizational account. Signing in to ArcGIS Online allows you to access and share GIS content with users in your organization as well as publicly with users around the world.
2)Click Sign In.
The application opens with the ArcGIS Pro dialog box.
Create a new project
1)To create a new project, click Blank.
2)Provide a New Project name: LARiverParkSite.
3)Browse to and select the C:\EsriPress\UGIS4 (Understanding GIS 4th Edition) folder as the location to save the new project folder.
4)Click OK.
When the new project opens, there will be a Contents pane on the left, a Catalog view in the middle, and a Catalog pane on the right. For more information on the Catalog pane and catalog view, see http://pro.arcgis.com/en/pro-app/help/projects/the-project-pane.htm.
Creating a project adds a new folder in the UGIS4 folder with the name you gave it, along with some default items, including a new geodatabase and a toolbox.
5)Select the Databases folder in the Contents pane. The Catalog view will be updated to show the items in the folder. Note that LARiverParkSite.gdb was created. This will be the default geodatabase for your project.
6)Select the Toolboxes folder in the Contents pane. Note that LARiverParkSite.tbx was also created when you started the project.
7)Close the Catalog view (large middle pane). Keep the Contents and Catalog panes open.
Insert a new map
1)On the Insert tab, click New Map.
A new map is added to the project using the Topographic map by default.
On the right side of the application is the Catalog pane. This pane contains all the maps, data, tools, and other resources associated with the project.
2)Open the Catalog pane (if necessary), and expand the Maps item.
Note that a new map simply named Map has been added to your project.
3)Rename the new map by right-clicking Map in the Catalog pane and clicking Rename. Type Lesson1a and press Enter.
Change the basemap to Streets
1)On the Map tab, change the basemap by clicking the Basemap button
2)Click the Streets basemap.
The World Street Map basemap layer is added to your Lesson1a map. It has an entry in the Contents pane on the left. Again, click the View tab, if necessary, to open the Contents pane.
The Map tab at the top of the application includes tools for navigation, layers, selections, inquiries, and labeling. As different tabs are selected—Insert, Analysis, View, Edit, and Share—different tools will appear on the ribbon. Additional contextual tabs, including Appearance, Labeling, and Data, will appear depending on the tasks that you are performing.
Zoom in to Southern California
Now you’ll zoom in to your area of interest.
1)Experiment with navigating the map with the mouse.
A.Push the scroll wheel forward to zoom in.
B.Pull the scroll wheel back to zoom out.
C.Drag in any direction with the left mouse button to pan.
D.Drag up with the right mouse button to zoom out.
E.Drag down with the right mouse button to zoom in.
F.Press and hold the Shift key and drag a box with the left mouse button to zoom in.
G.In the map window, use the Shift key to drag to draw a box around Southern California, as shown in the figure.
Your box doesn’t have to match exactly.
2)Zoom in again to get closer. When you see city names and major roads, pan (left mouse button) to center the view on the Los Angeles area.
3)Keep zooming in (try the Fixed Zoom In button
4)If you zoom in further than you want, zoom out
