Class Detail

eniro.maps.Coordinate(x, y, srs)

A (typed) coordinate which is a variant of point. The type is the spatial reference system used.

Class is considered a value type.

Parameters:
{number} x: The x (east-west) value.
{number} y: The y (north-south) value.
{eniro.maps.Srs} srs: The spatial reference system.

Method Detail

approxEquals(other, tol)

Compare this coordinate with the given one and tell if they are approximately equal using an optional tolerance. If the tolerance isn't specified it defaults to 5 meters.

Parameters:
{eniro.maps.Coordinate} other: The coordinate to compare to.
{number} tol Optional, Default: 5: The approximation tolerance in meters.

Returns:: true if this coordinate roughly equals the given one within the tolerance.

{boolean} equals(other)

Compare this instance with another instance.

Parameters:
{eniro.maps.Coordinate} other: The instance to compare this instance to.

Returns:: {boolean} true If this instance is equal to the given one.

{eniro.maps.Srs} getSrs()

Returns she spatial reference system.

Returns:: {eniro.maps.Srs} The spatial reference system.

{eniro.maps.Coordinate} transform(srs)

Transforms this coordinate to the spatial reference system given.

Parameters:
{eniro.maps.Srs} srs: The target srs to transform to.

Returns:: {eniro.maps.Coordinate} If srs differ, a new Coordinate otherwise this.
