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.

	    Option--Defined in--Default
	    proj    Geo::Shape	see Geo::Proj::defaultProjection()

	   . 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:

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
