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.)

Draw physically existing items along the borders of their projection on Earth's surface.

For example, when drawing items located on stylobates or building roofs, make sure they match the geometry of the stylobates or roofs. If necessary, shift them to match shifts in the stylobate or roof polygon drawn on the map:

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.

Items of any type that are under construction "exist" and can be drawn on the map as soon as the construction site for that project goes up.

Do not draw items that are still in the planning stages (i.e. before construction has started).


Items of the “Building” type are only drawn when their foundation appears in the actual location.

For the rules for drawing roads under construction, see Section Under construction.

Exception: If a planned street already has addresses associated with it but no roads are currently built or under construction for this street, you can still draw the street in its planned location using road sections with the Yes value set for the Under construction attribute.

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, aircrafts, ships, and other museum exhibits are classified under the “Culture and leisure” type (see Sections 3.6. Locations 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.

In some cases, employees (as part of individual tasks) may map, edit, and delete items in various layers to show large short-term events (such as festivals, sporting events, and so on).
