Geo::Space(3pm)

Usage

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

Inheritance

 Geo::Space
   is a Geo::Shape

Overview

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

Extends "DESCRIPTION" in Geo::Shape.

Methods

Extends "METHODS" in Geo::Shape.

Constructors

Extends "Constructors" in Geo::Shape.

$obj->new( [$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.

Attributes

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

Projections

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

Geometry

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.

Display

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.

example:

Overload

Extends "OVERLOAD" in Geo::Shape.

`overload: '""' (stringification)`	Inherited, see "OVERLOAD" in Geo::Shape
`overload: 'bool' (truth value)`	Inherited, 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
