copied!<p>Following the <a href="https://code.google.com/p/javaapiforkml/downloads/detail?name=JavaAPIforKml-apidocs.zip" rel="nofollow noreferrer">javadocs</a> (<a href="http://www.nilab.info/docs/jak091130/" rel="nofollow noreferrer">unofficial</a>) you need to check - using <code>instanceof</code> - each <code>Feature</code> whether is is a <code>Placemark</code>, if yes cast to it and get the <code>Geometry</code> which itself needs to be checked whether it is a <code>Polygon</code>, if yes then cast to it. After that the path to the coordinates is the following (just as it come in the kml-file):</p> <pre><code>getOuterBoundaryIs > getlinearRing > getCoordinates </code></pre> <p>Here is how it looks like in code:</p> <pre><code>@Test public void parseKml() { String src = "misctests/stackoverflow/kml/labasa.kml"; try(InputStream is = getClass().getClassLoader().getResourceAsStream(src)) { Assert.assertNotNull(is); Kml kml = Kml.unmarshal(is); Feature feature = kml.getFeature(); parseFeature(feature); } } private void parseFeature(Feature feature) { if(feature != null) { if(feature instanceof Document) { Document document = (Document) feature; List<Feature> featureList = document.getFeature(); for(Feature documentFeature : featureList) { if(documentFeature instanceof Placemark) { Placemark placemark = (Placemark) documentFeature; Geometry geometry = placemark.getGeometry(); parseGeometry(geometry); } } } } } private void parseGeometry(Geometry geometry) { if(geometry != null) { if(geometry instanceof Polygon) { Polygon polygon = (Polygon) geometry; Boundary outerBoundaryIs = polygon.getOuterBoundaryIs(); if(outerBoundaryIs != null) { LinearRing linearRing = outerBoundaryIs.getLinearRing(); if(linearRing != null) { List<Coordinate> coordinates = linearRing.getCoordinates(); if(coordinates != null) { for(Coordinate coordinate : coordinates) { parseCoordinate(coordinate); } } } } } } } private void parseCoordinate(Coordinate coordinate) { if(coordinate != null) { System.out.println("Longitude: " + coordinate.getLongitude()); System.out.println("Latitude : " + coordinate.getLatitude()); System.out.println("Altitude : " + coordinate.getAltitude()); System.out.println(""); } } </code></pre>
