This is a work-in-progress draft of a quick-start guide for pedestrian infrastructure mapping developed by the Pedestrian Working Group.

A work-in-progress draft of a full tagging schema for pedestrian infrastructure mapping is available here.

Tiers

A tier-based system is used to communicate which features and tags are possible with various resources and necessary for which use cases, as follows:

Icon	Name	Description	Use Cases	Required Resources
	Silver	Basic geometry and essential tags	Basic everyday pedestrian navigation	Low-quality aerial imagery
	Gold	Detailed geometry and tagging	Accessibility-focused applications	High-quality aerial imagery or low-quality street-level imagery
	Diamond	Micromapping and advanced tagging	Advanced routers and visualizations	High-quality street-level imagery or in-person survey

If, for example, you want to map pedestrian infrastructure so that it can be used for basic everyday routing and only have low-quality aerial imagery available, you would include only the features and tags marked with a Silver Tier symbol.

If you have access to high-quality imagery and want to map pedestrian infrastructure so that it can be used by accessibility-focused routers, you would include all features and tags marked with a Silver Tier symbol or a Gold Tier symbol.

Elements

Sidewalks

Sidewalk geometry forms the backbone of a navigable pedestrian infrastructure network.

• Sideway Way Tagging:

highway=footway + footway=sidewalk - Indicate sidewalk location

Crossings

Crossing ways and nodes communicate essential information for safe pedestrian travel.

• Crossing Node and Way Tagging:

crossing:markings=* - Specify presence and type of markings

crossing:markings=no - No markings [TODO: Image example]

crossing:markings=yes - Markings present, type unspecified

crossing:markings=zebra - Zebra markings [TODO: Image example]

crossing:markings=lines - Lines [TODO: Image example]

crossing:markings=* - Any other value

crossing:signals=* - Specify presence and type of signalization

crossing:signals=no - No signals [TODO: Image example]

crossing:signals=yes - Signals present, type unspecified

crossing:signals=shared - Vehicle traffic lights only [TODO: Image example]

crossing:signals=dedicated - Dedicated pedestrian traffic signals [TODO: Image example]

crossing:island=* - Presence of pedestrian island

• Crossing Way Tagging Only:

highway=crossing - Indicate crossing location [TODO: Screenshot example]

tactile_paving=* - Specify tactile paving presence at curb nodes

tactile_paving=yes - Tactile paving is present at both curbs [TODO: Image example]

tactile_paving=partial - Tactile paving is present at only one curb [TODO: Image example]

tactile_paving=no - Tactile paving is not present at either curb [TODO: Image example]

• Crossing Node Tagging Only:

highway=footway + footway=crossing - Indicate crossing location [TODO: Screenshot example]

tactile_paving=* - Specify tactile paving presence along crossing way

tactile_paving=yes - Tactile paving is present along the entire way [TODO: Image example]

tactile_paving=no - Tactile paving is not present along the entire way [TODO: Image example]

Curbs

Mapping curb details allows for accessibility-focused routing.

• Curb Node Tagging:

barrier=kerb - Indicate curb location [TODO: Screenshot example]

kerb=* - Specify curb type:

kerb=raised - Raised curb [TODO: Image example]

kerb=lowered - Curb ramp [TODO: Image example]

kerb=flush - Flush curb [TODO: Image example]

tactile_paving=* - Specify tactile paving presence

tactile_paving=yes - Tactile paving is present [TODO: Image example]

tactile_paving=no - Tactile paving is not present [TODO: Image example]

tactile_paving:colour=* - Specify color of tactile paving
