我在geomesa中使用Point
几何类型来获取要素类型中的强拉特细节。在存储新功能的用例中,我没有lat-long的值,所以我尝试为null
函数发送createPoint
对象,但是库'jts'在处理null时抛出异常几何类型。 Here是源代码。通过查看jts
库的实现,在geomesa Point中存储null似乎很困难。我有什么可能的选择?
这是我的代码的快照:
sf.setAttribute(Attributes.GEOMETRY.getValue(), JTSFactoryFinder.getGeometryFactory().createPoint((Coordinate)null/*new Coordinate(event.lat, event.lng)*/));
附加异常日志:
java.lang.IllegalStateException: getX called on empty Point

答案 0 :(得分:0)
GeoMesa是一个空间/时空数据库系统。因此,存储没有几何的数据不是主要用例。 GeoMesa中的许多指数都假定有效的经度 - 纬度点。
