Geo::WKT - Well Known Text representation of geometry information
Geo::WKT is a Exporter
# use coordinate pairs ... print wkt_linestring([1,2], [2,3], [3,2], [1,2]); # --> LINESTRING(1 2,2 3,3 2,1 2) # ... or coordinatie objects my $gp1 = Geo::Point->xy(6,7); my $gp2 = Geo::Point->xy(8,9); my $gp3 = Geo::Point->xy(6,9); print wkt_linestring($gp1, $gp2, $gp3); # --> LINESTRING(6 7,8 9,6 9) # Combine with Geo::Point registration of projections my $p = parse_wkt_point "POINT(3.5 6.7)", 'wgs84'; print $p->toString; # point[wgs84](6.7000 3.5000)
GIS application often communicate geographical structures in WKT format, defined by the OpenGIS consortium. This module translates Geo::Point objects from and to this WKT.
Parse any STRING into the applicable Geo::Shape structure.
Convert a WKT string into Geo::Space objects, containing the exterior and optionally some interior polygons.
Convert a WKT string into one Geo::Line object.
Convert a WKT string into one Geo::Point object.
Convert a WKT string into one Geo::Surface objects, containing the exterior and optionally some interior polygons.
Whole bunch of unsorted geometries. You may specify one Geo::Space or multiple things.
A line string is a non-closed list ('string') of points.
Format a list of lines into WKT. A line contains Geo::Point objects or ARRAY-REFs to coordinate pairs. You may also provide a Geo::Line or a Math::Polygon.
A set of points, which must be specified as list. They can be stored in a Geo::Space.
Format a list of closed lines into WKT. A line contains Geo::Point objects or ARRAY-REFs to coordinate pairs. You may also provide a Geo::Line or a Math::Polygon.
Pass any Geo::Shape object, and the easiest representation is returned.
Format one point into WKT format.
Format one polygon (exterior with optional interiors) into WKT format. An ARRAY contains Geo::Point objects or ARRAY-REFs to pairs. You may also provide a Geo::Line or Geo::Surface OBJECTS.
example:
wkt_polygon [2,3],[4,5]; #list of points for outer wkt_polygon $gp1, $gp2; #list of Geo::Points for outer wkt_polygon [[2,3],[4,5]]; #array of points for outer wkt_polygon [$gp1, $gp2]; #array with Geo::Points for outer my $outer = Geo::Line->new; wkt_polygon $outer; wkt_polygon $outer, $inner1, $inner2; wkt_polygon [$gp1,$gp2],[$gp3,$gp4,...];
