How long it takes for an area to be added to a map depends on a variety of factors, including the size of the area, the level of detail required, and the purpose of the map.
For example, large-scale maps of well-known areas like cities or countries can be produced relatively quickly, while more detailed maps of smaller areas may take longer to produce.
In addition, the process of surveying an area and creating a map can be complicated by factors like terrain, weather, and access to accurate GPS data. As a result, it can sometimes take months for newly discovered places to be added to maps.
However, advances in technology are making it possible to produce more accurate and detailed maps in a shorter amount of time.
