What can an ArcGIS user do to ensure that both parcel and building features are visible when displayed together?

Setting transparency on buildings is a practical method to ensure that both parcel and building features are visible when displayed together. By adjusting the transparency of the building features, the user allows underlying parcel features to be seen while still displaying the buildings. This enhances the visualization as it prevents one layer from completely obscuring the other, facilitating better analysis and interpretation of spatial relationships.

In scenarios where multiple layers overlap, transparency helps to create a clear view of all relevant data, making it easier for users to understand the context, relationships, and spatial distribution of various features. This technique is particularly useful when dealing with urban landscapes or any setting where multiple entities occupy the same geographical space.

The other options, while they may impact the display of features in some way, do not directly address the issue of visibility in the way that transparency does. For instance, changing the display order may organize the layers differently, but it does not guarantee visibility of all features simultaneously. Similarly, spatial joins and logical connections between features may create relationships but won’t enhance layer visibility in the same manner.
