GeoJSON is a format for encoding data about geographic features using
JavaScript Object Notation (JSON) [RFC7159]. Geographic features need not be
physical things; any thing with properties that are bounded in space may be
considered a feature. GeoJSON provides a means of representing both the
properties and spatial extent of features.

The GeoJSON format specification was published at http://geojson.org in 2008.
GeoJSON today plays an important and growing role in many spatial databases,
web APIs, and open data platforms. Consequently the implementers increasingly
demand formal standardization, improvements in the specification, guidance on
extensibility, and the means to utilize larger GeoJSON datasets.

This WG will work on a GeoJSON Format RFC that specifies the format more
precisely, serves as a better guide for implementers, and improves
extensibility of the format. The work will start from an Internet-Draft written
by the original GeoJSON authors: draft-butler-geojson [1].

This WG will work on GeoJSON mappings of 'geo' URIs, reinforcing the use of RFC
5870.

This WG will work on a format for a streamable sequence of GeoJSON texts based
on RFC 7464 (JSON Text Sequences) to address the difficulties in serializing
very large sequences of features or feature sequences of indeterminate length.

GeoJSON objects represent geographic features only and do not specify
associations between geographic features and particular devices, users, or
facilities. Any association with a particular device, user, or facility
requires another protocol. When a GeoJSON object is used in a context where it
identifies the location of a device, user, or facility, it becomes subject to
the architectural, security, and privacy considerations in RFC 6280, An
Architecture for Location and Location Privacy in Internet Applications. The
application of those considerations is specific to protocols that make use of
GeoJSON objects and is out of scope for the GeoJSON WG. Although the WG is
chartered to improve the extensibility of the format, extensions that would
allow GeoJSON objects to specify associations between geographic features and
particular devices, users, or facilities are not expected to be defined in the
WG. Should that be needed, re-chartering will be required.

Deliverables:

* A GeoJSON format specification document including mappings of 'geo' URIs
* A document describing a format for a streamable sequence of GeoJSON texts
