Final answer:
To adjust the transparency of a basemap in ArcGIS Pro, select the basemap in the Contents pane, go to the Appearance tab, and use the Transparency slider in the Effects group to set the desired opacity.
Step-by-step explanation:
To set the transparency of a basemap in ArcGIS Pro, follow these steps:
- Open your project in ArcGIS Pro and ensure that the basemap layer you want to adjust is added to the map.
- Select the basemap layer in the Contents pane. If the Contents pane is not visible, you can open it from the View tab on the main ribbon.
- With the basemap layer selected, go to the Appearance tab on the ribbon. This tab is context-sensitive and will appear when a layer is selected.
- Within the Appearance tab, locate the Effects group. Here you will find the Transparency slider.
- Click and drag the Transparency slider to adjust the opacity of the basemap. Alternatively, you can enter a specific value in the percentage box next to the slider to set the transparency precisely. The value can range from 0 (completely opaque) to 100 (completely transparent).
- As you adjust the slider, you will see the changes in the map view. When you are satisfied with the transparency level, you can stop adjusting the slider.
- Once the desired transparency is set, save your project to keep the changes.
Adjusting the basemap transparency allows you to control how much of the underlying data is visible through the basemap layers, which can be very helpful in various mapping scenarios.
