Overture Maps - Transportation

**Overview**
Overture's transportation layer is the collection of features and attributes that describe the infrastructure and conventions of how people and objects travel around the world. Transportation data includes highways, footways, cycleways, railways, ferry routes and public transportation.

1. Segments: Segments are paths which can be traveled by people or things. Segment geometry represents the center-line of a path which may be traveled. Segment properties describe both the physical attributes (e.g. road surface and width) and non-physical attributes (e.g. access restriction rules) of that path. Two Segments are physically connected if a common Connector is referenced from the connectors property of both Segments. Where this occurs, both Segment geometries must contain the common Connector's coordinates. A physical connection between Segments indicates that it may be possible to travel from one segment to the next at the connected location, provided the Segment properties do not indicate a restriction, such as a turn restriction, which would prevent the transition in a particular case. Conversely, two segments are not physically connected—even if their geometries intersect—if they do not share a Connector in common.
2. Connectors: Connectors create physical connections between Segments. Connectors help define the topology of the transportation network by defining points of physical connection between two or more Segments.

Founded in 2022 under the Joint Development Foundation, Overture Maps Foundation (Overture Maps) is dedicated to the development of reliable, easy-to-use, and interoperable open map data that will power current and next-generation map products. We build this data through a collaborative process that combines technology, data, and support from a wide range of companies. Map data are assembled from multiple sources including members, civic organizations, and open data sources.

However, if the data associated though GERS with an ODbL licensed theme constitutes a derivative dataset, it must be licensed under ODbL.

**Use cases**
- Mapping and geospatial visualizations: Rendering a map of connected roads and paths.
- Location Planning:
Build network of connected roads and paths and calculate optimal routes from place to place to for example plan the optimal location for your next warehouse.
- Location Geocoding:
Getting the coordinates of street intersections (geocodes) or the street intersection near specific coordinates (reverse geocodes)
