Collections GeoTools:创建点并将其添加到featureCollection
我正在实现轨迹点的插值。所以,基本上,我需要沿着从起点到终点的方位角创建几个点。问题是,我无法将创建的点添加到集合:Collections GeoTools:创建点并将其添加到featureCollection,collections,gis,point,geotools,Collections,Gis,Point,Geotools,我正在实现轨迹点的插值。所以,基本上,我需要沿着从起点到终点的方位角创建几个点。问题是,我无法将创建的点添加到集合: SimpleFeatureType featureType = featureSource.getSchema(); GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory(null); SimpleFeatureBuilder featureBuilder = new SimpleFeat
SimpleFeatureType featureType = featureSource.getSchema();
GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory(null);
SimpleFeatureBuilder featureBuilder = new SimpleFeatureBuilder(featureType);
SimpleFeatureCollection collection = featureSource.getFeatures();
/* Irrelevant code here
-----------------------
*/
Point2D newPt = setPointByAzimuth(startingPointCoords, azimuth, distance_to_next_point);
Point pointToCollection = geometryFactory.createPoint(new Coordinate(newPt.getX(), newPt.getY()));
featureBuilder.add(pointToCollection); //not quite sure what this does
SimpleFeature feature = featureBuilder.buildFeature(null);
collection.add(feature);
但是,当我运行此操作时,集合大小不会更改,并且不会向该集合添加任何内容。
我不确定这里有什么问题
谢谢,
尝试另一种方式:
- 创建并向其中添加您的点李>
- 然后使用将其添加到
MapContent
MapContent
。很抱歉,SimpleFeatureType对象存在问题,该对象已作为构造函数的形式参数应用于MemoryFeatureCollection,因此,没有显示任何内容。再次抱歉,您的解决方案帮助了我。
