WKTParser

A simple WKT (Well Know Text) parser grammar written for JavaCC.

The goal was to use it in a jEdit plugin, but you can use it for any other purpose

It does not support all WKT syntax but might be extended in the future.

Dependency

Available through Maven central

<dependency>
  <groupId>com.kpouer</groupId>
  <artifactId>wktparser</artifactId>
  <version>1.1.1</version>
</dependency>

Supported structures

• POINT
• LINESTRING
• POLYGON
• MULTIPOINT
• MULTIPOLYGON
• MULTILINESTRING
• GEOMETRYCOLLECTION

Example

Start start = new WKT(new StringReader("LINESTRING(30 10,-3.2011243453   -101.12124240)"))
    .Start();
LineString linestring = (LineString) start.jjtGetChild(0);
Point point1 = (Point) linestring.jjtGetChild(0);
Point point2 = (Point) linestring.jjtGetChild(1);

By default the parser will use JJT tree classes. But you could also use the shapes from com.kpouer.wkt.shape package that implements shapes using double values.

Polygon polygon = WKT.parseShape("POLYGON((40 40, 20 45, 45 30, 40 40))");
