Geo::Space(3pm) User Contributed Perl Documentation Geo::Space(3pm) 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 SEE ALSO
