I am working on a program using Eclipse. I added all the jars to my Java
and I managed to show multiple points and lines on the JMapFrame by adding
layers to the MapContent according to example codes online.
Now I am wondering if I can add a text string next to my point or line to
indicate the name of the location. I had a hard time finding the example
codes.
Below is the codes I used to create a layer with multipoints. Can anoyone
help me with creating a layer with text strings next to certain
coordinates? Thank you so much for your help.
Coordinate[] coordinates = getCoordinatesSequence();
SimpleFeatureTypeBuilder builder = new SimpleFeatureTypeBuilder();
builder.setName("feature");
builder.setCRS(DefaultGeographicCRS.WGS84);
builder.add("Location", Point.class);
final SimpleFeatureType TYPE = DataUtilities.createType("RoutePoints",
"points", "the_geom:MultiPoint");
SimpleFeatureBuilder featureBuilder = new SimpleFeatureBuilder(TYPE);
GeometryFactory geometryFactory = (GeometryFactory)
JTSFactoryFinder.getGeometryFactory();
MultiPoint points = geometryFactory.createMultiPoint(coordinates);
featureBuilder.add(points);
SimpleFeature feature = featureBuilder.buildFeature(null);
DefaultFeatureCollection featureCollection = new DefaultFeatureCollection(
"internal", TYPE);
featureCollection.add(feature);
Style style = SLD.createSimpleStyle(TYPE,Color.cyan);
Layer layer = new FeatureLayer(featureCollection, style);
Thanks.
Kind regards,
Johnny
