Geo::Space - A collection of various items
Geo::Space
is a Geo::Shape
my $island1 = Geo::Line->filled(...);
my $island2 = Geo::Space->new(...);
my $islands = Geo::Space->new($island1, $island2)
Where a Geo::Surface can only contains sets of nested polygons,
the Space can contain anything you like: lines, points, and unrelated
polygons.

- $obj->new( [$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()
Extends "Attributes" in Geo::Shape.
- $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()
- Inherited, see "Attributes" in Geo::Shape
- $obj->proj4()
- Inherited, see "Attributes" in Geo::Shape
Extends "Projections" in Geo::Shape.
- $obj->in( <$label|'utm'> )
- Inherited, see "Projections" in Geo::Shape
- $obj->projectOn($nick, @points)
- Inherited, see "Projections" in Geo::Shape
Extends "Geometry" in Geo::Shape.
- $obj->area()
- Returns the area enclosed by the combined components. Only useful when the
points are in some orthogonal projection.
- $obj->bbox()
- Inherited, see "Geometry" in Geo::Shape
- $obj->bboxCenter()
- Inherited, see "Geometry" in Geo::Shape
- $obj->bboxRing( [$xmin, $ymin, $xmax, $ymax, [$proj]] )
- Geo::Space->bboxRing(
[$xmin, $ymin, $xmax, $ymax, [$proj]] )
- Inherited, see "Geometry" in Geo::Shape
- $obj->distance( $object, [$unit] )
- Inherited, see "Geometry" in Geo::Shape
- $obj->perimeter()
- The length of the outer polygons of all components. Only useful in a
orthogonal coordinate systems.
Extends "Display" in Geo::Shape.
- $obj->deg2dm($degrees, $pos, $neg)
- Geo::Space->deg2dm($degrees,
$pos, $neg)
- Inherited, see "Display" in Geo::Shape
- $obj->deg2dms($degrees, $pos, $neg)
- Geo::Space->deg2dms($degrees,
$pos, $neg)
- Inherited, see "Display" in Geo::Shape
- $obj->dms2deg($dms)
- Geo::Space->dms2deg($dms)
- Inherited, see "Display" in Geo::Shape
- $obj->toString( [$projection] )
- Returns a string representation of the line, which is also used for
stringification.
