我在几何台面中使用Point
几何类型,以获得特征类型中强烈的经度细节。在存储新功能的用例中,我没有 lat-long 的值,所以我尝试为createPoint
函数发送null
对象,但库"jts"在处理空几何类型时抛出异常。这是源代码。通过查看jts
库的实现,似乎很难在几何台面点中存储null。我可以尝试哪些可能性?这是我的代码快照:
sf.setAttribute(Attributes.GEOMETRY.getValue(), JTSFactoryFinder.getGeometryFactory().createPoint((Coordinate)null/*new Coordinate(event.lat, event.lng)*/));
附加异常日志:

GeoMesa是一个空间/时空数据库系统。 因此,在没有几何图形的情况下存储数据不是主要用例。 GeoMesa中的许多索引都假定有效的经纬度点。
