我正在尝试构建一个CQL查询,以便在我的spartial数据库中找到某个形状。
我希望我的查询返回最大交点的形状。我的想法是设置LIMIT = 1和sortBy交集。
如果您看到附带的屏幕截图,我希望我的查询返回以下内容:
从左到右的三角形
有什么方法可以解决我的问题吗?
到目前为止我使用了以下代码:
Filter f1 = CQL.toFilter("INTERSECTS(the_geom, POLYGON((10.07051 53.23476, 10.08143 53.23512, 10.07596 53.22838, 10.07051 53.23476)))");
Filter f2 = CQL.toFilter("INTERSECTS(the_geom, POLYGON((10.06268 53.23756, 10.06889 53.23865, 10.06260 53.24903, 10.06268 53.23756)))");
Filter f3 = CQL.toFilter("INTERSECTS(the_geom, POLYGON((10.08146 53.24462, 10.09540 53.24761, 10.08247 53.26067, 10.08146 53.24462)))");
Query query = new Query( typeName, f3);
query.setMaxFeatures(1);
source.getFeatures(query);
SimpleFeatureCollection features = source.getFeatures(query);
SimpleFeatureIterator it = features.features();
while (it.hasNext()){
SimpleFeature sf = it.next();
System.out.println(sf.getAttributes());
}
