[Geotools-gt2-users] Forced Coordinate Display for LineString (Example) - More effective/better/flexible?

[Oliver G. <ol...@dr...>]

Hi,

I'm continuing my efforts with forced coordinate display by integrating LineString.

In a prior example I did multiple coordinate display for Points.

What I’m wondering is if there is anything more effective/better/flexible I can do then below for displaying a series of coordinates via LineString.

One line specifically that I wonder if could be done better is the following:
final SimpleFeatureType TYPE = DataUtilities.createType("Location", "location:LineString,name:String");

Any input would be greatly appreciated. :-)

Oliver

Below is my main source for forced coordinate LineString display.  Based on input from all you and alteration I will eventually put a full example on the forum.

public static void main(String[] args) throws Exception {
    final SimpleFeatureType TYPE = DataUtilities.createType("Location", "location:LineString,name:String");

    FeatureCollection collection = FeatureCollections.newCollection();

        
        double lon[] = {20.22, 30.33, 40.44};
        double lat[] = {20.22, 30.33, 40.44};
        String name="test";
        
        ArrayList cords = new ArrayList();

        for(int i=0;i<=2;i++){
            cords.add(new Coordinate(lon[i],lat[i]));
        }
         
        GeometryFactory factory = JTSFactoryFinder.getGeometryFactory(null);    
        
        CoordinateArrays ca = new CoordinateArrays();
        Coordinate[] cord = ca.toCoordinateArray(cords);
        
    LineString lineString = factory.createLineString(cord);
        SimpleFeature feature = SimpleFeatureBuilder.build( TYPE, new Object[]{lineString, name}, null );

    collection.add( feature );
        
        FeatureSource featureSource = DataUtilities.source(collection);
        MapContext map = new DefaultMapContext();
        map.setTitle("Quickstart");
        map.addLayer(featureSource, null);

        // Now display the map
        JMapFrame.showMap(map);
}
