Concepts

All Overture features share a set of common top-level properties. Each Overture data theme has its own core properties that define the feature types within that theme. For example, the place feature type must include a name property and a category property, in addition to the common set of Overture properties listed below.

Complex properties across themes​

Some feature properties used across themes are complex and require further explanation.

  • Names: where applicable, complex properties such as names will always use the same schema across all themes
  • Scoped and rule-based properties: a scoping property narrows the scope of its parent property and may only apply to a particular instance of the parent property; rule-based property is an array of rules, which are objects containing at least one scoping property
  • Cartography: cartographic properties are an optional set of "hints" for how to display Overture data in a map
