Scenery add-ons usually involve replacements for existing airports, with enhanced and more accurate detail, or large expanses of highly detailed ground scenery for specific regions of the world. Some types of scenery add-on replace or add structures to the simulator. Both freeware and payware scenery add-ons are very widely available. Airport enhancements, for example, range from simple add-ons that update runways or taxiways to very elaborate packages that reproduce every lamp, pavement marking, and structure at an airport with near-total accuracy, including animated effects such as baggage cars or marshalling agents. Wide-area scenery enhancements may use detailed satellite photos and 3-D structures to closely reproduce real-world regions, particularly those including large cities, landmarks, or spectacular natural wonders.
