Mapping Exit Numbers and Destinations in 30 US Cities

[poornibadrinath]

Task Objective

Adding Exit numbers and Destinations for Top 30 US Cities.

Team: @mapbox/india-office
Features to map: Exit Numbers and Destinations
Estimated features to map: Unknown
Estimated time to map: Unknown

Available Data Sources:

• Mapbox Satellite
• Bing
• Mapillary
• Wikipedia
• DOT documents for each city

Tasks:

Spreadsheet: Two team members can pick one state together and update this spreadsheet with the status of exit and destinations mapped.

The Progress of this task is being updated here

Mapping Workflow:
The detailed workflow for Exit mapping and Destination mapping

Mark any highway as DONE if it has been completely mapped or mark it as NO if it is not mapped and state the reason: No resources/ No Mapillary coverage.

JOSM Workflow:
Filters to use:

• Filter out non road features with boundary: | leisure: | landuse: | waterway: | amenity: | natural: | building:

• Add inverse filter: highway=motorway | motorway_link | trunk| trunk_link | primary | secondary | tertiary

• Layer:

  This layer can be used as guide to the city boundaries that a mapper is working on

In cases an exit is already tagged as noref=yes but there is good mapillary coverage in the the area, the exit should be double checked using mapillary images. Saw an instance in I-695 Washington, D.C where an exit was tagged as noref=yes but mapillary showed the exit ref as 1A.

Most cities has a ring road circling the city and it might not fit inside priority mapping area.

In such cases add all the missing exit numbers and destinations within the ring and every motorways inside even it is outside our priority mapping area.

Stats for the week of 2nd May - 5th May.

There are some nodes in the features with destination, destination:ref and destination:street tags. I've left it in there in the event you want to identify and remove/modify those features. Let me know if that has to be removed!

Feature	Count	Geojson
destination	408	destination.geojson
destination:ref	255	destination_ref.geojson
destination:street	48	destination_street.geojson
ref	28	ref.geojson
noref=yes	22	noref_yes.geojson
