3.2.1. Rules for selecting mapped objects
Draw items that exist in reality (both concrete items like homes, roads, bridges, etc., as well as immaterial borders of localities, sub-districts, etc.)
Items you draw should have defined borders. For example, you can't draw “the area around item N” since that area does not have definite borders.
Non-existent items (shifted borders, demolished or planned buildings, etc.) should not be mapped unless they relate to one of the exceptions listed below.
Demolished or partially demolished map items are still considered to "exist" for as long as remnants of that item are still at the site (for example, if the foundation of a demolished building is still there) and nothing has been built or is in the process of being constructed in their place.
For YME purposes, iems that are under construction "exist" as soon as the construction site for that project goes up. These items are drawn as buildings as soon as the foundation is laid. Do not draw items that are still in the planning stages (i.e. before construction has started).
Demolished or destroyed items that have been completely cleared away with nothing left on their previous site should not be drawn unless they are still visible on the satellite images being used. Furthermore, you should set Demolished as the value for the Condition attribute of the building. You should delete these items after the satellite images have updated.
Only draw stationary items on the map.
You can only draw mobile items (such as planes or military installations) if they become stationary (for example, as part of a monument or permanent museum exhibit) or are actually stationary (for example, permanently docked hotels or restaurants).
For YME purposes, items that are mobile but are part of a larger stationary item belong to the main item's type. For example, airplanes, ships, and other museum exhibitions are classified under the “Culture and relaxation” type (See sections 3.6. Places and 3,7. Territories.
Moving items that are not actually movable (stationary floating hotels or floating restaurants, etc.) are drawn as buildings that belong to the corresponding category (restaurants belong to the “Culture and leisure” category, and berthing barges are classified as “Residential buildings”, etc.); see section 4.2.1. Building type.
You can draw temporary “Locations” (dolphinariums, circuses, etc.) on the map if they will operate in that location for at least two months.
