how to change viewing angle in arcmap

In ArcMap, you can change the viewing angle, particularly when working with 3D data in a 3D view like ArcScene or by using ArcGIS Pro. In ArcMap, the main 2D interface does not support a true "viewing angle" adjustment, but you can manipulate your data display and perspective somewhat. However, if you are referring to a 3D environment, here’s how you can adjust the viewing angle in ArcScene or ArcGIS Pro: ### ArcScene: 1. **Open or Create a 3D Scene**: If you're using ArcScene, either open an existing scene or create a new one with 3D data. 2. **Navigate the View**: - Use the **Navigation Toolbar**: - **Rotate**: Click and hold the `Shift` key while dragging with the left mouse button to rotate around the center of the view. - **Tilt**: Hold the `Ctrl` key and drag with the left mouse button to tilt the view. - **Move**: Use the scroll wheel to zoom in and out, or hold the right mouse button to pan around. 3. **Adjust View Properties**: You may also adjust settings in the **View** menu if you wish to alter the perspective or other properties (e.g., vertical exaggeration). ### ArcGIS Pro: 1. **Open 3D View**: Create or open a project with a scene view. 2. **Change the Viewing Angle**: - **Mouse Navigation**: Similar to ArcScene: - Right-click and drag to pan, scroll to zoom, and hold `Shift` while dragging to rotate the view. - **Navigate Ribbon**: You can use the **Navigate** tab to select tools for different navigation options, such as changing altitude and angle. 3. **View Properties**: - Check the Properties pane to set specific parameters related to your scene’s viewing angle and altitude. 4. **Camera Tools**: In ArcGIS Pro, you can also use the camera tools to set specific views. By following these methods, you can manipulate the viewing angle of your project in both ArcScene and ArcGIS Pro. If you're using ArcMap and looking for a specific function related to changing the viewing angle, please clarify your request, as ArcMap is primarily for 2D data visualization.
