Road outline / curb line

1

If I export a section of open street map to OSM format how can I find the curb lines for the streets it shows?

e.x. at this URL: https://www.openstreetmap.org/export#map=19/40.66848/-73.94072

I found this data for "President Street" (replacing "<" with "[")

[way id="250220325" visible="true" version="1" changeset="19296424" timestamp="2013-12-05T21:03:43Z" user="Rub21_nycbuildings" uid="1781294"] [nd ref="2567030383"/] [nd ref="2567030387"/] [nd ref="2567030377"/] [nd ref="2567030367"/] [nd ref="2567030359"/] [nd ref="2567030357"/] [nd ref="2567030369"/] [nd ref="2567030379"/] [nd ref="2567030385"/] [nd ref="2567030390"/] [nd ref="2567030692"/] [nd ref="2567030689"/] [nd ref="2567030871"/] [nd ref="2567030874"/] [nd ref="2567030988"/] [nd ref="2567030964"/] [nd ref="2567030675"/] [nd ref="2567030670"/] [nd ref="2567030383"/] [tag k="addr:housenumber" v="1419"/] [tag k="addr:postcode" v="11213"/] [tag k="addr:street" v="President Street"/] [tag k="building" v="yes"/] [tag k="height" v="9.2"/] [tag k="nycdoitt:bin" v="3033440"/] [/way]

I understand that each node ([nd]) corresponds to a node with latitude/longitude but these are just down the center of the street.

How can I find the nodes of the EDGE of the street?

BTW, the example you gave is actually a building at 1419 President Street, not the street itself.

You cannot. With the exception of pedestrian areas and some experimental road-area mapping in Germany, OSM only ever maps the street centreline and not the curb. The maps you see will draw the street using a line width that is derived from the street type (highway tag), and in some cases also taking into consideration the width or lanes tags, but never based on actual curb line mapping.

You can probably contact your local government planning office, they will likely have a copy of the cadastre, which includes the curb line.
