class GeoJSON::Point

Overview

A Point is a Geometry representing a single Position in geographic space.

This class corresponds to the GeoJSON Point.

Defined in:

geojson/point.cr

Constructors

.new(longitude, latitude, altitude = nil, bbox = nil)
Creates a new Point at the given longitude, latitude, and optional altitude, and with optional bounding box bbox.
.new(pull : JSON::PullParser)
A Point is a Geometry representing a single Position in geographic space.
.new(coordinates : GeoJSON::Coordinates, *, bbox = nil)
Creates a new Point with the given coordinates and optional bounding box bbox.
.new(coordinates : Array(Float64), *, bbox = nil)
Creates a new Point with the given coordinates and optional bounding box bbox.
