使用空间数据库查找包含点的多边形 [英] Using a spatial database to find polygons that contain a point

问题描述

我正在使用MongoDB来存储空间记录.一些记录是多边形，而另一些是点.数据正在不断插入.

I'm using MongoDB to store spatial records. Some records are polygons, and others are points. Data is being continually inserted.

我需要能够访问其多边形包含一个点的所有记录. Mongo的空间查询允许查找多边形内的所有点，但不能找到包含一个点的所有多边形.在另一个数据库系统MongoDB中，有什么好方法吗?

I need to be able to access all records whose polygon contains a point. Mongo's spatial queries allow finding all points within a polygon, but not all polygons that contain a point. Is there a good way to do this in MongoDB another database system?

推荐答案

不幸的是，目前无法运行此查询-除非您愿意简化应用程序(即，假设所有多边形都是a的圆)特定半径[或小半径集].

Unfortunately, there is no way to run this query at present -- unless you're willing to simplify the application (i.e., assume all polygons are circles of a particular radius [or small set of radii]).

有一张您描述的功能的公开票证: https://jira.mongodb.org/browse/SERVER-2874

There's an open ticket for the functionality you described: https://jira.mongodb.org/browse/SERVER-2874
