Data

Data⚓︎

This section explains how to explore pedestrian network data in the OS-CONNECT Data Viewer, including feature types, attributes, and how to view feature details.

For a list of all guides on the TCAT Wiki, refer to the Guides List.

Viewing Data⚓︎

To view pedestrian network features on the map, ensure the Data toggle is enabled in the layer toggles.

Data toggled

The Data Viewer displays feature data as colored lines and points on the map. To view detailed attributes for individual features, zoom in to zoom level 16 or higher.

Tip

Zoom level is shown in the URL. Refer to URL Format for more details.

Hovering Over Features⚓︎

When you zoom in to zoom level 16 or higher, you can hover over (or tap on touch devices) any feature on the map to view a popup containing its attributes.

Feature hover popup showing attributes

The popup displays the following attributes when available:

Attribute Description Example Values
highway The type of way footway
footway The sub-classification of the footway sidewalk, crossing
kerb The type of curb lowered, flush, raised
barrier The type of barrier kerb
incline The slope grade of the feature, expressed as a percentage 5%, -3%
width The width of the feature in meters 1.5
length The length of the feature in meters 42.3
foot Whether the feature permits pedestrian access yes, no
surface The surface material of the feature concrete, asphalt
tactile_paving Whether tactile paving (detectable warning surfaces) is present yes, no

Note

Not all attributes are present for every feature. The popup only displays attributes that are present in the dataset for that specific feature.

Feature Types⚓︎

The OS-CONNECT Data Viewer displays eight types of pedestrian network features, each rendered in a distinct color on the map. These features follow the OpenSidewalks schema.

Sidewalk⚓︎

Sidewalks are pedestrian paths that run alongside a road. They are the most common feature type in the dataset and form the backbone of the pedestrian network.

  • Color: Light blue
  • Identified by: highway=footway + footway=sidewalk

Crossing (Marked)⚓︎

Marked crossings are designated pedestrian paths across a road that have visible pavement markings (e.g., painted lines, zebra stripes).

  • Color: Yellow
  • Identified by: footway=crossing + crossing:markings=yes

Crossing (Unmarked)⚓︎

Unmarked crossings are designated pedestrian paths across a road that do not have visible pavement markings.

  • Color: Tan/orange
  • Identified by: footway=crossing + crossing:markings=no

Footway⚓︎

Footways are general pedestrian paths that are not categorized as sidewalks or crossings. These may include paths through parks, pedestrian plazas, or other dedicated walking areas.

  • Color: Red-orange
  • Identified by: highway=footway (without a footway sub-classification)

Kerb (Lowered)⚓︎

Lowered kerbs ("curb ramps") are curb transitions where the curb height has been reduced to facilitate access, typically at crossings.

  • Color: Teal
  • Identified by: barrier=kerb + kerb=lowered

Kerb (Flushed)⚓︎

Flushed kerbs ("flush curbs") are curb transitions where the curb is level with the road surface, providing a seamless transition between the sidewalk and the roadway.

  • Color: Dark teal
  • Identified by: barrier=kerb + kerb=flush

Kerb (Raised)⚓︎

Raised kerbs are standard curbs that maintain their full height, which may present a barrier to wheelchair users.

  • Color: Green
  • Identified by: barrier=kerb + kerb=raised

Traffic Island⚓︎

Traffic islands are raised or protected areas within a roadway that provide a refuge for pedestrians crossing wide or multi-lane roads.

  • Color: Purple
  • Identified by: highway=footway + footway=traffic_island
