About

WKB is a Java library for writing and reading Well-Known Binary Geometries to and from bytes. The library includes a hierarchy of Geometry objects. Although developed as part of the GeoPackage Libraries, this library does not contain GeoPackage functionality and can be used separately.

Usage

View the latest Javadoc

Read

//byte[] bytes = ...    

ByteReader reader = new ByteReader(bytes);
reader.setByteOrder(ByteOrder.BIG_ENDIAN);
Geometry geometry = WkbGeometryReader.readGeometry(reader);
GeometryType geometryType = geometry.getGeometryType();

Write

//Geometry geometry = ...

ByteWriter writer = new ByteWriter();
writer.setByteOrder(ByteOrder.BIG_ENDIAN);
WkbGeometryWriter.writeGeometry(writer, geometry);
byte[] bytes = writer.getBytes();
writer.close();
