Hey everyone, welcome back to another GIS tutorial! Today, we're going to talk about how to view negative Z values in 3D ArcGIS Pro. Negative Z values represent the elevation below a defined reference point, and it's crucial to be able to visualize and analyze this aspect of spatial data. Here are the steps to effectively view negative Z values in 3D ArcGIS Pro:

1. Open your 3D scene in ArcGIS Pro and add the layer containing the spatial data with negative Z values to the map.

2. Navigate to the 'Appearance' tab on the ribbon and select the 'Symbology' pane.

3. In the Symbology pane, locate the 'Elevation' section and click on the 'Elevation' tab.

4. Under the Elevation tab, you'll find the 'Extrusion' option. This is where you can specify how the Z values are visualized in the 3D scene.

5. To effectively view negative Z values, adjust the 'Extrusion' properties to ensure that features with negative Z values are accurately represented below the reference point.

6. You can also use the 'Surface' option to further enhance the visualization of negative Z values when working with elevation data.

7. Once you've made the necessary adjustments, take some time to navigate through your 3D scene and observe how the negative Z values are being portrayed.

By following these steps, you'll be able to effectively view and analyze negative Z values in 3D ArcGIS Pro, gaining valuable insights from your spatial data. Understanding the elevation variations, including negative Z values, is crucial for various applications such as terrain analysis, urban planning, and environmental modeling.

That's it for today's tutorial! I hope you found this information helpful for your spatial analysis projects. Stay tuned for more GIS tips and tricks, and don't forget to like and share this video. Happy mapping!
