Properties

lon

{Float} The x-axis coodinate in map units

lat

{Float} The y-axis coordinate in map units

Constructor

OpenLayers. LonLat

Create a new map location.

Parameters

lon	{Number} The x-axis coordinate in map units. If your map is in a geographic projection, this will be the Longitude. Otherwise, it will be the x coordinate of the map location in your map units.
lat	{Number} The y-axis coordinate in map units. If your map is in a geographic projection, this will be the Latitude. Otherwise, it will be the y coordinate of the map location in your map units.

Functions

toShortString

toShortString:function()

Returns

{String} Shortened String representation of OpenLayers.LonLat object. (ex. <i>”5, 42”</i>)

clone

clone:function()

Returns

{OpenLayers.LonLat} New OpenLayers.LonLat object with the same lon and lat values

add

add:function( lon,
lat )

Parameters

lon	{Float}
lat	{Float}

Returns

{OpenLayers.LonLat} A new OpenLayers.LonLat object with the lon and lat passed-in added to this’s.

equals

equals:function( ll )

Parameters

ll	{OpenLayers.LonLat}

Returns

{Boolean} Boolean value indicating whether the passed-in OpenLayers.LonLat object has the same lon and lat components as this. Note: if ll passed in is null, returns false

transform

transform: function( source,
dest )

Transform the LonLat object from source to dest. This transformation is in place: if you want a new lonlat, use .clone() first.

Parameters

source	{OpenLayers.Projection} Source projection.
dest	{OpenLayers.Projection} Destination projection.

Returns

{OpenLayers.LonLat} Itself, for use in chaining operations.

wrapDateLine

wrapDateLine: function( maxExtent )

Parameters

maxExtent

{OpenLayers.Bounds}

Returns

{OpenLayers.LonLat} A copy of this lonlat, but wrapped around the “dateline” (as specified by the borders of maxExtent)
