Read Shapefile extent with Geotools

Is there any possibility to get the extent of a Shapefile using the GeoTools library? I want to read the TOP, LEFT, BOTTOM, RIGHT coordinates from the SHP.

Seems like there is no kind of getExtent() method...

Solution

  • I haven't compiled the following but it should work. 

    File file = new File("example.shp");
Map map = new HashMap();
map.put( "url", file.toURL() );
DataStore dataStore = DataStoreFinder.getDataStore(map);

SimpleFeatureSource featureSource = dataStore.getFeatureSource( typeName );
SimpleFeatureCollection collection = featureSource.getFeatures();

ReferencedEnvelope env = collection.getBounds();
double left = env.getMinX();
double right = env.getMaxX();
double top = env.getMaxY();
double bottom = env.getMinY();
