      3 In the upper right, click the magnifying glass to open the search box, type owner:esripress_GettingToKnowArcGISPro Pedestrian and Bicycle Accidents - Wilmington, DE, and press Enter. Adding this text (owner:esripress_GettingToKnowArcGISPro) limits the search results to content uploaded by the Esri Press organizational account associated with this book. Your search results may not return anything. By default, search results are limited to content within your organization, so you will set an option to show results from all public content on ArcGIS Online.

      4 Under Content, turn off the option to Only Search In Your ArcGIS Organization.A web map named Pedestrian and Bicycle Accidents - Wilmington, DE appears in the search results.

      5 Click the title to see its item details page. The map description provides an overview about the map, including the owner, description, map layer contents, and other properties.Note: A new Map Viewer with added functionality is being implemented across the ArcGIS platform. Users have the option to access the beta version of Map Viewer in ArcGIS Online. This chapter uses the release version of Map Viewer, but you will learn about the beta version in exercises throughout the remainder of the book.

      6 Click Open In Map Viewer (or click the thumbnail image). If necessary, click the Content button. The map shows pedestrian and bicycle accidents from 2011 to 2014 in Wilmington, Delaware. The Contents pane contains six layers—a layer for each year, plus a municipal boundaries layer and a topographic basemap provided by ArcGIS Online. Layers have a check box so that you can turn them on and off. The basemap is always on and has no check box.You will change the basemap to more clearly see the precise locations of accidents. Basemaps provide a backdrop and frame of reference for operational layers, such as accidents. As you zoom in, the basemap provides more detail. In this case, you see topographic details. In other basemaps, you might see the ocean floor. In the satellite basemap, for example, you can see your house, school, or workplace.

      7 Click the Basemap button to show the Basemap Gallery. Select the Streets basemap, and zoom out until your map extent roughly matches the figure.When you point your cursor to any of the operational layers, you can see icons and tools that allow you to show the legend, show the attribute table, change styles, filter data, perform analysis, and other tasks.

      8 Move the Accidents 2014 layer to the top of the Contents pane, and then turn off all layers except the Accidents 2014 layer.

      1 To view the current symbology of the Accidents 2014 layer, click the Show Legend button below the layer name.As you learned earlier, the blue square symbol represents pedestrian accidents and the blue triangle symbol represents bicycle accidents.

      2 Under the Accidents 2014 layer name, click the Change Style button. A check mark shows that the layer is symbolized based on Types (Unique Symbols) to display the Pedestrian attribute, which has only two unique values: pedestrian and bicycle. Next, you will change the symbols to something more meaningful.

      3 Under Select A Drawing Style, click Options.

      4 Click the Pedestrian blue square icon to change the symbol.

      5 In the Change Symbol pane that appears, click the Shape tab. Select Transportation from the drop-down list, and click the red exclamation point in a triangle. Adjust the symbol size to 18, and click OK.

      6 Similarly, choose an appropriate symbol and size for the Bicycle icon (the yellow exclamation point in a triangle is suitable), and click OK.

      7 At the bottom of the Change Style pane, click OK, and then click Done to return to the Contents pane.
