ALKMaps.Geometry.Curve

A Curve is a MultiPoint, whose points are assumed to be connected. To this end, we provide a “getLength()” function, which iterates through the points, summing the distances between them.

ALKMaps.Geometry.MultiPoint

Summary

ALKMaps.Geometry.Curve	A Curve is a MultiPoint, whose points are assumed to be connected.
Properties
componentTypes	{Array(String)} An array of class names representing the types of components that the collection can include.
Constructor
ALKMaps.Geometry.Curve
Functions
getLength	{Float} The length of the curve
getGeodesicLength	Calculate the approximate length of the geometry were it projected onto the earth.

Properties

componentTypes

{Array(String)} An array of class names representing the types of components that the collection can include. A null value means the component types are not restricted.

Constructor

ALKMaps.Geometry.Curve

Parameters

point

{Array(ALKMaps.Geometry.Point)}

Functions

getLength

getLength: function()

Returns

{Float} The length of the curve

getGeodesicLength

getGeodesicLength: function( projection )

Calculate the approximate length of the geometry were it projected onto the earth.

projection

{ALKMaps.Projection} The spatial reference system for the geometry coordinates. If not provided, Geographic/WGS84 is assumed.

Returns

{Float} The approximate geodesic length of the geometry in meters.
