Data types and tilesets

  • Two new data types, locality and legislative, will be included as part of the product to complement the existing data types of administrative, postal, and statistical.
    • The locality data type will have 4 levels that aim to capture local expectations of settlements that have non-official or fuzzy areas: Level 1 = Metro --> Level 2 = City --> Level 3 = District --> Level 4 = Neighborhood.
    • The legislative data type will have 5 levels that capture electoral boundaries: Level 1 = National Upper (aka US Senate) --> Level 2 = National Lower (aka US House of Representatives) --> Level 3 = Regional Upper (State Senate) --> Level 4 = Regional Lower (State House) --> Level 5 = Local (Community or Town specific boundaries).
  • Separated lines and points tilesets that enable the inclusion of names on a map from the points tilesets.

Data coverage improvements

  • US scope expanded to include cities and municipalities. The definition of a city is fluid in how it’s used and perceived by people. To avoid misrepresenting a boundary, we used several data types and levels to properly capture US city and municipality boundary polygons.
  • Admin, level 3 = US county sub-divisions that are active governments or entities with designated officials that provide primary general-purpose functions to their residents.
  • Admin, level 4 = US census incorporated places (excludes Census Designated Places, or CDPs, which are only statistical).
  • Stats, level 3 = all US county sub-divisions (all serve a statistical purpose, while only some serve an administrative purpose).
  • Locality, level 2 = this level was created to provide a one-stop location to provide what people colloquially refer to as a city in the US. It is constructed by using all US county sub-divisions as a basis, then adding all US census places (both incorporated and CDPs).
  • Completed a full review of all global Administrative boundaries, which resulted in recategorizing several boundaries to a statistical or legislative level as the purpose, function, or both purpose and function of those boundaries was changed by the government.
