Function: longlat( )

Syntax

longlat(<point>{,<projection>,{,<units>}})

Type

point

Returns

The inverse projection of a point in Cartesian space into longitude/ latitude. The resulting values of the answer are in degrees.

Parameters

• <point>
  The point to be inverse-projected.

• <projection>
  The cartographic projection to use. If omitted, the current projection mapping is used. If the projection has a supplied datum shift, the returned point will be based on the WGS84 ellipsoid, otherwise it will be based on the ellipsoid supplied with the projection.

• <units>
  A string value defining the units for <point>. If this is omitted, the value of the system string units is assumed. This cannot be the value "ll" (long/lat degrees).

Examples

point ll = longlat(mypoint)

point ll = longlat(mypoint,amg55)

point ll = longlat(mypoint,mercator,'km')
