Lesson 8

Present your analysis results

COMMUNICATING YOUR FINDINGS to a diverse audience of readers, with levels of sophistication ranging from public citizens to council members to the city’s urban planners who must ultimately design an actual park, is no easy task.

Your analysis has yielded a short list of candidate sites that you want to present to the city council and other interested parties. You’ll make your presentation in the form of a map that places the results in a meaningful geographic context, addresses the project guidelines, and follows good cartographic design principles.

The deliverable item is an 8½ x 14-inch map that can be printed or viewed on-screen.

But wait, you may be thinking, what’s wrong with simply adding the layer of recommended sites to an online basemap, as you already did in lesson 6? There’s nothing wrong with it, and basemaps will be part of your map design, but your map design must accomplish a lot of things. You’ll be adding inset maps, customizing the positions of labels and other text, and incorporating other standard cartographic elements such as a scale bar and north arrow.

Your analysis results aren’t too complex. You basically want to show just the study area, represented by the LA River buffer zone, and the six proposed park boundaries. You want to set these analytical layers against a backdrop of topography, place-names, and major roads. Perhaps the biggest design challenge you face is that these six locations are small parcels of land strung out over a 20-mile stretch of river corridor: How do you map the area of interest without rendering the parks too tiny to see at that scale? The solution lies in the use of inset maps—smaller maps placed within the main map, each one portraying a closeup view of a particular site.

Cartography involves innumerable choices about color, font, line width, placement and juxtaposition of elements, and so on. These are often somewhat subjective decisions, with many good (and bad!) possibilities. This lesson takes you through the creation of an exact design (shown in the figure at 50 percent actual size), but along the way you’ll have the option to alter things to suit your own taste. Explanations are given as to why certain choices were made, but you don’t have to follow the instructions with total fidelity. Experimenting with some of the settings will give you a deeper understanding of how the software works and a chance to make a map that suits your own aesthetic tastes.

A full presentation of this type in the real world might include a variety of media products, such as large-format wall maps, smaller notebook-size maps, printed reports, digital slide shows, PDF downloads, web maps, and websites. All these things cannot be done without writing another book, so the focus here is going to be on a single map layout that can be printed on a standard legal-size piece of paper. In lesson 9, you’ll go a step further and take your results to the web, but for now, your working medium will be a sheet of legal-size paper.

An 8½-by-14-inch map is small, but it would be worse if you were trying to pack a lot more features or a lot of detailed data into this format. This size is used in recognition of the fact that many people don’t have access to larger-format printing devices. And if you can design well in a small format, you’ll feel that much more comfortable and creative when you begin working in larger formats.

A good way to begin a map layout—just like an analysis—is with a sketch of your basic plan. The sketch for your map is shown in the figure.

Exercise 8a: Create the main map

Beginning with this exercise, you’ll create a new map that will be used for the map layout.

Create a new map for layout

1)Start ArcGIS Pro, and open the LARiverParkSite project.

2)Close any maps or tables that may be open.

3)Make a copy of Lesson6e, and rename it Lesson8.

4)Open the Lesson8 map.

5)Auto-hide the Catalog pane by turning off or on the Auto-Hide from pinned to unpinned .

By default, panes stay open as you work. You can auto-hide a pane so that it doesn’t take up space when you’re not using it.

6)Remove the Bright Map Notes layer.

7)Use a blue symbol for the LARiver layer (if one is not already set).

8)Change the basemap to Topographic.

9)Change the map projection of Lesson8 to WGS 1984 Web Mercator Auxiliary Sphere. This option should be under Map Properties > Coordinate System > Layers.

10)Zoom to the LARiverBuffer layer.

The World Topographic Map basemap will make an unobtrusive background, with topographic relief that will make the map less starkly flat. All the basemaps in ArcGIS Pro are based on WGS 1984 Web Mercator Auxiliary Sphere and therefore will display the least amount of distortion of features and text for your map layout.

Symbolize the LA River buffer

In lesson 6, you created the LARiverBuffer feature class. You’ll now symbolize it using a hatched fill symbol for use in your layout.

1)Open the Symbology pane for LARiverBuffer.

2)In the Symbology pane, click on the symbol to open symbol formatting, and if necessary, switch to the Properties tab and then the Layers view .

3)Deselect the check box next to Solid stroke to hide that property.

4)Select the check box next to the buffer polygon, and change the drop-down menu from Solid fill to Gradient fill.

5)Change the colors to white and a shade of green.

6)Expand Pattern, and confirm Direction is set to Buffered. Change Interval to 40. The Interval property defines how many bands are drawn across the buffer.

7)Keep Extent at Relative, and change Size to 20%. The Extent and Size properties define how much of the feature is covered by the color scheme in an absolute distance or a relative percentage.

8)Click Apply.

9)Change the LA River buffer transparency to 30% on the Appearance tab.

Why make the buffer green? One reason is that you have many layers to symbolize, and green works well in combination with the other colors you’re going to use. On a psychological level, by using green you’re also suggesting that this area is a verdant, riparian habitat—whereas, in reality, much of it is either densely developed residential/commercial land or industrial blight. Are you misleading your audience or just being optimistic? Whichever way you think of it, you must be aware as a cartographer that symbols may have hidden meanings as well as overt ones.

Add and symbolize the LA city limits

You only considered locations within Los Angeles itself, so it will be helpful to show the city limits on the map.

1)In the Catalog pane, browse to your MapsAndMore folder, drag the Los Angeles.lyrx file to Contents, and drop it right above the Basemap layer. (A horizontal gray bar marks the spot.)

When you drop a layer on the map, it takes its natural place in the top-to-bottom drawing order (point, line, polygon, and raster). When you place it in the Contents pane, it goes exactly where you put it.

2)Change the symbol for the new Los Angeles layer to use the Yellow (Bright) symbol from the Gallery view.

3)On the Appearance ribbon, change Layer Transparency to 95%.

The result is a subdued yellow mask on top of the basemap. White space shows through areas that aren’t part of Los Angeles proper.

Set the map extent

At the moment, the map is zoomed to the extent of the LARiverBuffer layer. Although this is your area of interest, you must make a little more room around the edges for inset maps.

1)Below the map, set the map scale to 1:160,000.

At this scale, one inch on the map equals about 2½ miles on the ground. With your ArcGIS Pro window maximized, the map extent should be close to that of the figure, although the result depends on such things as the size and screen resolution of your monitor. For your purposes, the extent is more important than the scale.

2)On the Map tab, in the Navigate group, create a bookmark named LA River Layout Extent.

Symbolize recommended sites

The six recommended sites are the most important features on your map, but they’re so small and close together that you must do some creative symbology to make them show up. In the sketch at the beginning of the lesson, red circles were used to represent the site locations, and balloon labels were used to designate Site ID and acres. You’ll create these effects here by symbolizing the RecommendedSites layer (a polygon layer) as a point marker and creating callout text symbols. Because you can easily enlarge the symbols to a size that will draw the map reader’s attention, you’ll use them as substitutes for the small-site polygons. It will still be important to show the actual shapes and sizes of the sites, and to do that, you’ll create inset maps in exercise 8b.

1)Turn on the RecommendedSites layer, if necessary, and open its attribute table.

2)Confirm that it shows the field aliases and formatting from lesson 6, and close the table.

3)Open Symbology for RecommendedSites.

4)In the Symbology drop-down menu, confirm that Symbology is set to Single Symbol.

5)Select the symbol to open Format Polygon Symbol.

6)Click Properties, and then click the Structure button .

7)Under Layers, click Add symbol layer and then Marker layer.

8)Delete the line and polygon layers by clicking the Delete Layer button next to each layer, leaving only the Marker layer.

9)Switch to the Layers tab.

10)Under Appearance > Form, click Style, and then Circle 3. Click OK.

11)Change the size to 6 pt.

12)Expand Marker Placement, and change Placement to At Center.

13)Compare to the figure, and click Apply.

Each of the six sites is symbolized with red circles at the center of each polygon.

On the map, the symbols stand out prominently. Cartographers often use bright colors (called “spot colors”) for the features they most want to call attention to on the map.

Label the sites

You’ll use the SiteID field to label the sites.

1)Highlight RecommendedSites, if necessary, and click the Labeling ribbon. On the far left of the ribbon, in the Layer group, click the Label button to enable it.

2)Just to the right of the Label button, in the Label Class group, click the Field drop-down arrow, and click SiteID.

3)In the Text Symbol group, expand the gallery, and scroll down to Layout. Click Callout (Sans Serif).

4)Click the Text Symbol button in the lower-right corner of the Text Symbol group to open the Label Class pane.

5)Confirm that the Symbol tab is selected at the top of the pane (between Class and Position) and that the General tab is selected (below Class).

6)Expand Callout, and change the color to Poinsettia Red to match the Marker layer color. Click Apply.

The labels are now drawing with the correct style but are overlapping in areas in which you have groups of sites, such as sites 4, 5, and 6. You’ll apply an offset to separate the labels.

7)Click the Position tab at the top of the pane, and expand the Placement group.

8)Set the Preferred offset to 10.0. When you are finished, close the Label Class pane.

9)Zoom to the LA River Layout Extent bookmark. Your Lesson8 map should look similar to the figure. If all of the labels aren’t displayed, try zooming in.

10)Save your project.

11)If you’re continuing to the next exercise, leave ArcGIS Pro open. Otherwise, close ArcGIS Pro.

In this lesson, you’ve symbolized the layers that make up the Lesson8 map. In the next exercise, you’ll create a new layout using both an LA River map and inset maps to show close-ups of the sites.

Exercise 8b: Create a layout using the LA River and inset maps

You’ll now be working in an ArcGIS Pro layout. Viewing and working with data is one thing; composing a map for the printed page is something else. In composing a map, you must take into account not only your design considerations but also output constraints such as paper size, page orientation, and print margins. Map composition is done in a layout—the graphical, page layout environment of ArcGIS Pro.

Create a new layout frame

1)On the Insert tab, in the Project group, click New Layout.

2)Under the ANSI – Landscape section, click Legal. In the Contents pane, name the new layout Lesson8. Also, note that the new layout has been added to the Layouts folder in the Catalog pane.

3)Insert a map frame using the LA River Layout Extent bookmark.

The idea of a map frame takes on new significance in a layout. In a map (where you’ve worked until now), a map frame is an abstract “container” of layers. Apart from one or two special properties, such as its coordinate system setting that controls on-the-fly projection, you generally don’t pay much attention to it. In a layout, the map frame is visual: it’s a rectangular window placed on a virtual sheet of paper, and it serves as a key element in the map composition.

In the template, the default margins around the map frame are set to one inch on all sides. Most of this space would be wasted in your layout, because you’re going to place all the map content—data and marginalia both—directly in the map frame. You’ll enlarge the map frame, leaving just a minimum amount of white space around the edge of the page.

4)Under Contents, right-click Map Frame, and click Properties.

5)In the Element Map Frame pane, click Placement, and change the Width to 13.5 and Height to 8.

6)Change X to 0.25 and Y to 0.25.

7)Close the Format Map Frame pane.

8)Click the Layout tab.

Now is a good time to make a distinction between the navigation tools on the Layout tab for the map frame and the map layout itself.

The icons for navigation tools on the Layout tab, in the Navigate group, show an 8½ × 11-inch “page” in the background of the layout. These are the tools used to navigate around the actual map layout.

The Layout navigation tools magnify, reduce, and otherwise adjust your view of the map layout. They do not change the scale or extent of the map within the map frame.

•Try zooming in and out of the page using the scroll wheel.

•Pan using the mouse button. Press the Shift key to enable a Zoom In tool.

•Use the Full Extent button to return to the entire map layout.

9)On the Layout tab, in the Map group, click the Activate button .

Note that the ribbon changes again, and you are now manipulating the map that resides within the map frame.

10)Zoom in to the LA River, and use the mouse to pan around the map.

Note the map scale below the map is changing as you zoom in and out of the map.

11)Use the LA River Layout Extent bookmark to return to the overview.

While still in Activation mode, you want to reposition your LARiverBuffer more precisely in your layout to make room for your insert maps and charts.

12)Use the zoom tools and map scale to position the buffer similar to the figure. This will give you room to the north and east of the buffer for the inset maps and charts.

13)Go back to the layout by going to the Layout tab, and in the Map group, click Close Activation .

The ribbon resets for manipulating the layout.

Both sets of tools work in layout view, so you must be careful which navigation tools you are using.

Create a new map of recommended sites

1)Insert a new map, and name it Lesson8 Recommended Sites.

2)Change the basemap to imagery. At the large scale of the inset map, imagery will show the site as it really looks. (Keep in mind that basemap layers are updated periodically, so your imagery may look different.)

3)In the Catalog pane, add the RecommendedSites feature class from the AnalysisOutputs project geodatabase.

4)Open the Symbology pane, and change the fill color to No color, the Outline color to Solar Yellow, and the Outline width to 3 pt.

5)Click Apply.

Now you’ll create bookmarks for each of the recommended sites to make it easier to add them to your layout.

6)Open the attribute table of the RecommendedSites layer.

7)In the attribute table, right-click the gray square next to the first record (siteid1), and click Zoom To.

8)Create a bookmark, and name it Site 1. This set of bookmarks will be saved under the Lesson8 Recommended Sites bookmarks.

9)Zoom to each of the following sites, 2–6, and make a bookmark of each site.

Name each site by its site ID number.

10)Close the attribute table of the RecommendedSites layer.

Place inset maps

An inset map is a small, supplementary map that shows part of the main map’s area at a larger scale. It reveals detail not apparent at the scale of the main map. (An overview map, by contrast, shows the main map at a smaller scale to place it in the context of its surroundings.)

You want map readers to have a closeup look at each of the sites, so you’ll create six large-scale inset maps. You can’t simultaneously set different map scales within a single map frame (except with viewer windows), so you must insert some new map frames. In fact, you’ll insert six of them and place them around the main map as shown in our layout sketch.

1)Open the Lesson8 layout .

The layout tab has a layout icon next to it, and the map tab has a map icon next to it.

You’ll insert a new map frame to contain your first inset map.

2)On the Insert tab, in the Map Frames group, click the drop-down arrow on Map Frame. Scroll down the list of bookmarks to Lesson8 Recommended Sites, and click Site 1.

3)In the Contents pane, open the properties of the new map frame, and under Options , rename it Site 1.

4)Under Display , change border line width to 0.5 pt, and set the border symbol color to Gray 40%.

5)Under Placement , set Width and Height to 1.5. The values default to inches (in.).

Don’t worry about the X and Y position values: you’ll position the map frame manually.

6)Close the Element pane.

7)On the Lesson8 layout, the Site 1 map frame is resized and renamed. If necessary, activate the map frame, and zoom in so no other site boundaries show. Make sure to close Activation if the map frame was activated.

When you add a basemap layer, the data providers are credited on the basemap itself. In data view, these credits appear as an icon in the lower-right corner of the map frame. (Clicking the icon opens the credits in a window.) In layout view, the credits are displayed as text. You may have noticed them before in the main map, but you can’t miss them in the inset map, which is overwhelmed by the text. These credits can’t be deleted, but they can be manipulated. In exercise 8c, you’ll incorporate them into other data acknowledgments, but for the time being, you want to move them out of the way.

8)On the Insert tab, in the Text group, click Dynamic Text and then Service Layer Credits (near the bottom of the list).

Both sets of credits are moved out of their respective map frames and into a text box on the layout. The text box is selected.

9)Drag the text box anywhere outside the boundary of the layout page.

10)Click some empty white space to deselect the box.

With the service layer credits moved aside, you can turn your attention back to the inset map. Service layer credits are important, because they provide credit to the basemap data providers. Therefore, you will add some data attribution later in the lesson.

Label the sites

You want to label the recommended sites with their Site IDs and areas so the map reader knows their ID number and how big they are. As you get closer to finishing the map, you’ll be increasingly concerned with the exact placement and appearance of the text on the map.

1)Open the Lesson8 Recommended Sites map.

2)Open the RecommendedSites attribute table, and under the Menu button, click Fields View.

3)Change the numeric format of Acres to one decimal place by clicking Numeric and the Expand button to open the Number Format pane.

4)Save your changes, and close the Fields View table.

5)Confirm that the Acres field is displaying only one decimal place, and then close the RecommendedSites attribute table.

6)Select the RecommendedSites layer.

7)On the far left of the Labeling ribbon, in the Layer group, click Label to turn on labels.

8)In the Text Symbol group, change the font to Arial (or a similar font if that’s not available) and the size to 8 pt.

9)Set the color to Solar Yellow and the type to Bold.

10)Click the More Options button in the lower-right corner of the Text Symbol area of the ribbon.

11)Expand the Halo group, and select the black rectangle from the Halo symbol drop-down menu. Then confirm that Halo size is 1 pt.

12)Click Apply. The labels now have a halo around them to help make them stand out against the outline of the parcel and basemap.

13)Switch to the Position tab by clicking Position at the top of the Label Class pane (next to the Symbol tab).

14)Under Placement, click Regular Placement, if necessary.

15)Click Straight in Polygon.

16)Confirm that the check box next to May place label outside polygon boundary is selected.

17)Close the Label Class pane.

18)In the Label Class group, click Expression.

A label expression lets you add custom text to an attribute value to make a more informative label.

19)In the Expression dialog box, for Language, click VBScript. Remove [Acres] and type the new expression as follows: "Site " & [SiteID] & vbnewline & [ACRES] & " Acres". Check your expression against the figure.

The expression tells ArcGIS Pro to take the word “Site” and tack on a space, and then add the value from the SiteID field. Add a new line, and then take the value from the ACRES field and tack on a space and then the word “Acres.” Without the expression, the map reader wouldn’t know what the units were.

20)Click Apply at the bottom of the Expression dialog box, and then close the Label Class pane.

The labeled feature should look similar to the figure.

Since there isn’t enough room to put all the inset maps right next to their sites, you’ll move them to convenient locations, as shown in the layout sketch at the beginning of the lesson.

21)On the Lesson8 layout, select the Site 1 map frame. (You should see the white selection handles.)

22)Drag the map frame to the lower-right corner of the main map, just to the left of the river buffer, as shown in the figure.

Create the rest of the inset maps

1)On the Layout tab, in the Clipboard group on the far left, use the copy and paste functions to make a duplicate of the Site 1 map frame. The duplicate copy will be pasted right on top of the original Site 1 map frame in the map layout, so you’ll need to move the copy off of Site 1.

2)Activate the duplicate of the Site 1 map frame you just moved by right-clicking on the map frame and clicking Activate.

3)On the Map tab, use Bookmarks to zoom to the Site 2 location.

The inset map zooms in to Site 2. In each inset map, you’re letting the site boundary fill the map frame. That means the inset maps will be at different scales from each other—a fact you’ll note on the map later on.

4)After confirming that the map frame is now zoomed to Site 2, on the Layout tab, in the Map group, click Close Activation.

5)Under Contents, select Site 2, and on the layout, drag the Site 2 map frame to the approximate position shown in the figure, right above recommended sites 1 and 2.

6)Repeat the process, using steps 1–5, to create four more inset maps. Use the figure to guide your placement of the map frames. In summary, the steps are as follows:

•On the Layout tab, copy and paste the map frame you just made.

•Activate the new map frame.

•On the Map tab, use Bookmarks to zoom to the site location. Feel free to change the zoom level if desired.

•On the Layout tab, click Close Activation.

•Drag the map frame to the appropriate place on the layout.

7)In the Contents pane, drag the inset map frames into sequential order.

8)When you’re finished, save your project.

Create charts on demographic data

You know each site meets your minimum demographic requirements, but it would be nice to compare them graphically to find out if one or more stand out as especially well qualified. You’ll create bar graphs of median household income, population density, and the percentage of children.

1)Open the Lesson8 map.

2)Right-click on the RecommendedSites layer, and select Create Charts > Bar Chart.

3)In the Chart Properties pane under Data, select SiteID from the Category or Date drop-down menu. Change Aggregation to <none>.

4)Under Fields, use the pull-down menu to select Median Household Income. Change the Label to Median Household Income ($).

5)Expand Axes, and change the Maximum value to 50000.

6)Change from Data to General, and modify the Chart title to Median Household Income.

7)Close the Chart Properties pane.

Hovering over any of the bars in the graph will reveal SiteID and Income values.

You can now add the new chart to your layout.

8)Close the Median Household Income chart, and open the Lesson8 layout.

9)Confirm that the Map Frame layer is selected in the Contents pane.

10)From the Insert ribbon, use the Chart Frame drop-down menu to select the Median Household Income chart.

11)Double-click on the chart to open the Format Chart Frame pane.

12)Under Options, change the Name to Median Household Income.

13)Under Display, change the Border Symbol to black with 0.5 pt and a Background Symbol color of white.

14)Under Placement, change the Size for Width and Height to 2.5 in.

15)Move the Median Household Income chart to the upper-right corner of the layout.

16)Return to the Lesson8 map, and create a second bar chart on RecommendedSites, this time using People per Square Mile for the chart Field.

17)Change the Chart title to Population Density. Keep all the other defaults.

18)Create a third chart using % Under 18.

19)Change the Chart title to Percent of Children. Keep all the other defaults.

20)Close any open charts when finished.

Note: You can return to your charts by selecting List by Charts in the Contents pane of the Lesson8 map.

21)On the Lesson8 layout, insert the two new charts, applying the same settings as with Median Household Income.

22)Position the new charts under the Median Household Income chart.

Exercise 8c: Finish the map

To finish the map, you’ll add a title, scale bar, north arrow, and acknowledgments.

Add a map title

You want the title to have the largest and most prominent typeface on the layout.

1)On the Insert tab, in the Text group, click the Text drop-down arrow, and then click Rectangle to create a new rectangle paragraph for a title box.

2)Draw a box in any open space on the layout.

3)Open the properties of the Text element that was added to Contents.

4)Under Options, expand General, and change the name to Title.

5)Under Text, enter Potential LA River Park Site Locations in the text box. Delete the space between “River” and “Park,” and then press Enter to add a line break.

6)Under Text Symbol, expand Position, and select centered text for Horizontal alignment. Click Apply.

7)On the Format tab, change the font to Arial and the size to 36 pt.

8)In the Current Selection group on the far left, change to the Background element.

9)Select a green for the background color.

10)Switch to Border, and add a black line border.

11)Resize the Title box, and place it in the open space at the top of the layout. Confirm that the title is at the top of the Contents pane.

Add a Pacific Ocean label

You should identify the Pacific Ocean on the layout. By convention, text for bodies of water is italicized.

1)Zoom and pan to the ocean area.

2)On the Insert tab, in the Text Group, click Curved Text.

3)Use the tool to create a curved path along the coastline. Add two to three points, and double-click to end the line.

4)In the text box on the map, type Pacific Ocean.

5)On the Format tab, change the font to Arial with Italic. Keep the font size at 12 pt, and choose a dark-blue color.

6)As you did for the title, in the Contents pane open the properties of the text layer and rename it Pacific Ocean.

Add a river buffer label

You’ll add one more label to clarify what the LA River buffer represents.

1)Zoom in to the area between the 405 and 101 Freeways (to the right of the Site 4 inset map).

2)Using steps 2 and 3 from the previous section, create a curved label just to the south of the buffer.

3)Type LA River 1/2 mile corridor.

4)On the Format tab, change the font to Arial with Bold. Change the font size to 12 pt, and choose a dark-green color.

5)In the Contents pane, open the properties of the text layer, and rename it LA River buffer label.

Add a scale bar to the main map

A scale bar will give the map reader a sense of distance on the map.

1)On the Insert tab, in the Map Surrounds group, click the Scale Bar drop-down arrow.

In the drop-down menu, you can choose from a variety of scale bar types.

2)In the Imperial group, select Single Division Scale Bar.

3)On the Scale Bar Design tab, make the following changes:

•In the Divisions group, change Resize Behavior to Adjust width.

•Change Division Value to 3.

•Keep Divisions at 1 and Subdivisions at 0.

•In the Numbers group, change Position to Center on bar.

4)On the Scale Bar Format tab, make the following changes:

•Change the Fill color to Arctic White.

•Change the width to 0.5 pt.

•Change the point size to 9 pt.

5)Move the scale bar from the middle of the layout to a position below the Pacific Ocean label on the layout.

Scale bars and scale text

Scale bars provide a visual indication of the size of features and the distance between features on the map. A scale bar is a line or bar divided into parts and labeled with its ground length, usually in multiples of map units such as tens of kilometers or hundreds of miles. If the map is enlarged or reduced, the scale bar remains correct. You can also represent the scale of your map with scale text, which is a verbal expression of scale. Scale text may relate equivalent units (“one inch equals two miles”) or be a representative fraction that holds for any units (for example, “1:100,000”). Scale text will be wrong if the map is enlarged or reduced after it has been printed.

Add a north arrow

You’ll add a north arrow to remove any ambiguity about directions.

1)On the Insert tab, click the North Arrow drop-down arrow to choose a north arrow.

You need a slender arrow to economize on space in the corner of the map, but feel free to choose one you like.

2)Select ArcGIS North 3.

3)On the North Arrow Format tab, change the size to 36 pt.

4)Move the north arrow from the middle of the layout to a position above your scale bar.

Add data attribution

It’s important to acknowledge data sources. Credits for the World Topographic Map basemap layer are included in the service layer credits. You also want to credit the City and County of Los Angeles, which provided much of the project data. Finally, you want the map reader to know that the inset maps are at different scales. You’ll combine all this information in one text element, which you’ll work on in the next set of steps.

Earlier, in exercise 8b, you added dynamic text for the basemap credits and dragged them off the layout.

1)Drag the text box back, and place it in the open space to the left of your north arrow and scale bar, and resize it so that it fits nicely. Not all the text will fit, so you’ll reformat the text.

2)With the text box still selected, change the font to Arial Regular 7 pt and Gray 50%.

3)Double-click on the Layer Credit text box to open its properties.

The service layer credits are a type of dynamic text, which changes on the basis of the current properties of the map. If you had navigated to a different part of the world, the text displayed on the map layout would change to show the sources used on the basemap. Dynamic text uses tags, much like HTML, as placeholders for the text to be displayed and allows for the combination of dynamic and static text.

4)In the Format Text pane, on the Text tab, under Options > Text, position your pointer at the end of the line, and add two new lines by typing Shift + Enter twice.

5)Add the following text: Inset maps are at different scales.

6)Compare your edits to the figure.

7)Resize the text box, and reposition it in the lower-left corner of the map to fit the space without crowding the other elements.

8)Save your project.

In the next section, you’ll preview, export, and print the map. If you see any final adjustments you want to make, now is the time to do it. Look at the final map at the end of this lesson for reference.

Preview and share your map

If you have a printer available, you can print your map.

1)On the Layout tab, click the Full Extent button.

Your layout should resemble the figure.

2)On the Share tab, in the Export group, click Layout.

3)Browse to your MapsAndMore folder, and export your layout as a JPEG.

4)If you have access to a printer, you can also print from this same ribbon by clicking Layout in the Print group.

5)Close all the Lesson8 maps and layout.

6)Save your changes, and close ArcGIS Pro.

The next, and final, phase of the project, in lesson 9, is to share your analysis results online with a web map.
