我正在尝试插入一个使用圆处理器生成圆点的位置。文档中的位置[30，10]是使用圆点正确生成的。docs：圆处理器|ElasticSearch指南[8.5]|弹性

But if I use another location. The generated coordinate looks like an oval with the wrong radius.

这是一个问题还是它的工作如预期？因为坐标不是一个圆，所以它影响了搜索结果.

按热度按时间ubbxdtey1#
你需要用longitude first and then latitude指定你的坐标数组，我想你做了相反的事情，你的圆在南极洲的中间。
如果你这样做：
那么你的圆看起来就不再是椭圆了：
从official doc：
在GeoJSON和WKT以及Elasticsearch中，正确的坐标顺序是坐标数组中的longitude，latitude（X，Y），这与许多地理空间API（如Google Maps）不同，后者通常使用通俗的latitude，longitude（Y，X）。
