NAME

       Geo::Space - A collection of various  items

INHERITANCE

        Geo::Space
          is a Geo::Shape

SYNOPSIS

        my $island1 = Geo::Line->filled(...);
        my $island2 = Geo::Space->new(...);
        my $islands = Geo::Space->new($island1, $island2)

DESCRIPTION

       Where a Geo::Surface can only contains sets of nested polygons, the Space can contain
       anything you like: lines, points, and unrelated polygons.

METHODS

   Constructors
       $obj->new([COMPONENTS], [OPTIONS])
       Geo::Space->new([COMPONENTS], [OPTIONS])
           When called as instance method, some defaults are copied from the object where the
           call is made upon.  Usually called as class method.

           COMPONENTS are Math::Polygon, Math::Polygon::Surface, Geo::Point, Geo::Line,
           Geo::Surface, Geo::Space objects.

           proj => LABEL

   Attributes
       $obj->component(INDEX, [INDEX, ...])
           Returns the component (or components) with the specified INDEX(es). One Geo::Shape
           object in scalar context, and multiple in list context.

       $obj->components()
           Returns a list of Geo::Shape objects, all located in this space.

       $obj->lines()
           Returns a list of Geo::Line objects, which are defined as separate components.

       $obj->nrComponents()
           Returns the number of components.

       $obj->onlyLines()
           Returns true when all components are lines; Geo::Line objects.

       $obj->onlyPoints()
           Returns true when all components are points; Geo::Point objects.

       $obj->onlyRings()
           Returns true when all components are closed lines; Geo::Line objects each defined as
           ring.

       $obj->points()
           Returns a list of Geo::Point objects, which are defined as separate components.

       $obj->proj()
           See "Attributes" in Geo::Shape

       $obj->proj4()
           See "Attributes" in Geo::Shape

   Projections
       $obj->in(LABEL|'utm')
           See "Projections" in Geo::Shape

       $obj->projectOn(NICK, POINTS)
           See "Projections" in Geo::Shape

   Geometry
       $obj->area()
           Returns the area enclosed by the combined components.  Only useful when the points are
           in some orthogonal projection.

       $obj->bbox()
           See "Geometry" in Geo::Shape

       $obj->bboxCenter()
           See "Geometry" in Geo::Shape

       $obj->bboxRing([XMIN, YMIN, XMAX, YMAX, [PROJ]])
       Geo::Space->bboxRing([XMIN, YMIN, XMAX, YMAX, [PROJ]])
           See "Geometry" in Geo::Shape

       $obj->distance(OBJECT, [UNIT])
           See "Geometry" in Geo::Shape

       $obj->perimeter()
           The length of the outer polygons of all components. Only useful in a orthogonal
           coordinate systems.

   Display
       $obj->deg2dm(DEGREES, POS, NEG)
       Geo::Space->deg2dm(DEGREES, POS, NEG)
           See "Display" in Geo::Shape

       $obj->deg2dms(DEGREES, POS, NEG)
       Geo::Space->deg2dms(DEGREES, POS, NEG)
           See "Display" in Geo::Shape

       $obj->dms2deg(DMS)
       Geo::Space->dms2deg(DMS)
           See "Display" in Geo::Shape

       $obj->toString([PROJECTION])
           Returns a string representation of the line, which is also used for stringification.

           example:

OVERLOAD

       overload: '""' (stringification)()
           See "OVERLOAD" in Geo::Shape

       overload: 'bool' (truth value)()
           See "OVERLOAD" in Geo::Shape

DIAGNOSTICS

       Error: distance calculation not implemented between a $kind and a $kind
           Only a subset of all objects can be used in the distance calculation.  The limitation
           is purely caused by lack of time to implement this.

       Error: in() not implemented for a $class
