Abstract

   This document describes the GeoJSON text sequence format and
   "application/geo+json-seq" media type.  This format is based on
   JavaScript Object Notation (JSON) Text Sequences and GeoJSON, and
   makes arbitrarily large geographic datasets incrementally parseable
   without restricting the form of GeoJSON texts within a sequence.

1.  Introduction

   Arbitrarily large sequences of values pose a problem for JavaScript
   Object Notation (JSON) [RFC7159] that is well explained in the
   motivation for JSON Text Sequences [RFC7464].  The GeoJSON format
   [RFC7946] faces the same kind of problem.  Geographic datasets often
   run to the tens of thousands or millions of features.  The problem is
   often amplified by the presence of large arrays of coordinates for
   each of the features.

   This document describes a specialization of JSON Text Sequences.  A
   GeoJSON Text Sequence is a document of arbitrarily large size
   containing one or more GeoJSON objects, e.g., multiple GeoJSON texts
   that can be produced and parsed incrementally, and not only a single
   GeoJSON FeatureCollection, Feature, or Geometry.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   [RFC2119].

2.  GeoJSON Text Sequence Format

   Defined in prose, following [RFC7464]: a GeoJSON text sequence is any
   number of GeoJSON [RFC7946] texts, each encoded in UTF-8 [RFC3629],
   each preceded by one ASCII [RFC20] RS character, and each followed by
   a line feed (LF).

   The GeoJSON Text Sequence Format conforms to all the rules of
   [RFC7464] and adds the following constraint: each JSON text MUST
   contain a single GeoJSON object as defined in [RFC7946].
