Many shooting games provide a radar-view on screen. This is an overview of the map, usually with some indication of enemies or targets. In an architectural context, you can add a minimap. This is a separate camera-view, in overlay on top of the regular view. You can either have a single broad view showing the whole scene or a smaller section, following the main navigation.
