In considering the use of a building as an aerial checkpoint, what is a good accompanying feature for positive identification?

When selecting a building as an aerial checkpoint, it is critical to choose features that are easily recognizable and distinguishable from the air. A cemetery, or graveyard, is often a good accompanying feature for positive identification due to its distinctive layout and appearance, which typically includes well-defined boundaries, distinct rows of headstones, and often large trees or landscaping that make it stand out against surrounding urban or rural settings.

These elements, together with the structure of the building, create a strong visual contrast that enhances the ability to accurately identify the aerial checkpoint. Other features, while they may also be recognizable, might not have the same level of distinctive characteristics or contrast in appearance that a cemetery does. In the case of schools, parks, or shopping centers, these locations can be more variable in design and layout, making them potentially confusing or less reliable as identifiers from an aerial perspective. Thus, the use of a cemetery as an accompanying feature complements the identification of the building effectively.
