Inherits:

• Parse::GeoJSON::LineString

Defined in:

lib/parse/model/geojson.rb

Overview

‘LineString` — an ordered sequence of `[longitude, latitude]` points describing a path. The most common applications are GPS tracks, delivery routes, road segments, and trail centerlines.

GeoJSON requires ≥ 2 points; this class warns when the constraint is violated rather than raising, matching Parse::GeoPoint / Polygon validation style.

Examples:

Parse::GeoJSON::LineString.new [[-122.4, 37.7], [-122.39, 37.78]]
