A relation tagged type=multilinestring is a discontiguous series of unclosed ways that semantically represents a single physical object.

Rationale

This relation type is named by analogy with multipolygon relations. The term "MultiLineString" comes from the Simple Features specification, an ISO/OGC standard, which also defines the terms "MultiPolygon" and "LineString". The type=multilinestring tag has been included in two separate proposals, Proposed features/Multilinestring and Relations/Proposed/boundary segment.

When to use

This relation type is used when a single physical object would qualify as a multipolygon, except that it covers no area because it consists of linear features (unclosed ways). For example, some mappers use multilinestring relations when micromapping geoglyphs (man_made=geoglyph) that resemble written text.

Do not use this relation type for a collection of independent linear features just because they are thematically related, because relations are not categories.

Tags to use in combination

  • inscription=* for the text that the multilinestring spells out
