NAME¶

Geo::Converter::WKT2KML - Simple converter between WKT and KML

SYNOPSIS¶

    use Geo::Converter::WKT2KML;
    
    # Convert WKT to KML's geometry fragment
    wkt2kml('POINT(135 35)');
    
    # Convert KML's geometry fragment to KML
    kml2wkt('<Point><coordinates>135,35</coordinates></Point>');

DESCRIPTION¶

    This module provides two functions, wkt2kml and kml2wkt.
    These are convert geometry formats WKT (Well-Known Text) and KML 
    each other.
    
    This module can interpret only geometry fragment of KML, cannot
    interpret full spec KML.
    Only elements can be understood are:
     * Point
     * LineString
     * Polygon
     * MultiGeometry
     * (Belows are child elements of aboves)
     * coordinates
     * LinearRing
     * outerBoundaryIs
     * innerBoundaryIs 
    WKT is also understood full spec one.
    "POINT ZM ..." or "POLYGON EMPTY" are cannot interpreted.
    Only commands can be understood are:
     * POINT
     * MULTIPOINT
     * LINESTRING
     * MULTILINESTRING
     * POLYGON
     * MULTIPOLYGON
     * GEOMETRYCOLLECTION

EXPORT¶
