whosonfirst-data

Who's On First is a gazetteer of places. Not quite all the places in the world but a whole lot of them and, we hope, the kinds of places that we mostly share in common.

A gazetteer is a big list of places, each with a stable identifier and some number of descriptive properties about that location. An interesting way to think about a gazetteer is to consider it as the space where debate about a place is managed but not decided. We call our gazetteer "Who's On First" (or sometimes "WOF" for short).

Data from Who's On First. <a href="http://whosonfirst.mapzen.com#License">License</a>

The Who's On First dataset is both original work and a modification of existing open data. Some of those open data projects do require attribution. We have listed all sources below.

When we source other open data projects we make best effort to indicate them (e.g.: 'src:geom':naturalearth) and we also include the original source's properties prefixed with the following names spaces:

gn - GeoNames (CC-BY)
gp - GeoPlanet Where on Earth, aka woe (CC-BY)
ne - Natural Earth (Public Domain)
oa - OurAirports (Public Domain)
qs - Quattroshapes (CC-BY)
zs - Zetashapes (CC-BY)

Please notify us if you believe that an open data project has not been properly noted.

Our original work is generaly indicated with properties prefixed with wof or is not prefixed (like name).

Remember, some sources require attribution, some do not. Mapzen's original work, including the format and structure that allows Who's On First to operate, is made available under the Creative Commons Zero designation, and a shout out would be lovely.

Sources

Who's On First makes use of a number of open data sources, some of whom do require attribution. Please note that original sources may be modified.

GeoNames

Properties with the gn prefix are from GeoNames.

Examples: gn:id for GeoNames identifier concordance, and src:centroid_lbl:geonames indicate the source of our label centroid is GeoNames.

GeoNames database is licenced as follows:

The GeoNames geographical database is available for download free of
charge under a creative commons attribution license.

More details can be found at: http://www.geonames.org/about.html

GeoPlanet

Properties with the gp prefix are from GeoPlanet.

Sometimes the woe prefix is used instead because GeoPlanet supersedes Where on Earth (WOE) and not all data has been updated.

Examples: gp:id for GeoPlanet identifier concordance, and localized names (eg: name:chi_p, name:ger_p, and name:kor_p).

GeoPlanet database is licenced as follows:

Natural Earth

Properties with the ne prefix are from Natural Earth.

Example: ne:name for the Natural Earth feature name.

Natural Earth is released as follows:

OurAirports

Properties with the oa prefix are from OurAirports.

Example: oa:elevation_ft for the elevation in feet.

OurAirports files are released as follows:

Quattroshapes

Properties with the qs prefix are from Quattroshapes.

Examples: qs:id for Quattroshapes identifier concordance and qs:adm0 for country names.

Who's on First doesn't always use the Quattroshapes geometry, so review that in src:geom. When we do, some Quattroshapes features source from friendly CC0 or Public Domain licensed projects, and others from a stricter CC-BY project: check that in the qs_source property. For example, qs_source:EuroGlobalMap means you'll need to give specific credit to one or more European national mapping agencies as further described below.

Quattroshapes are licensed as follows:

license.

Please include attribution in your app, site, or printed work. Sample
wording: "Includes data from foursquare quattroshapes" with a link to

Zetashapes

Properties with the zs prefix are from Zetashapes.

Examples: If we source our default geometry from Zetashapes we say that in src:geom: zetashapes. We list which US Census Blocks compose the Zetashapes geometry in zs:blockids, and a few other properties like zs:pop10 for population count.

Zetashapes polygons and data are subject to the following:

The polygons generated by this site do not have any added restrictions
beyond the base data from TIGER and Flickr.

By submitting votes to this site you are agreeing that your votes will

this data that there is flickr data associated with it.
