[英]MongoDB / Geojson $geointersects problems
It's been now 8 hours I'm trying to deal with a MongoDB Geojson $geoIntersects issue:现在已经 8 小时了,我正在尝试处理 MongoDB Geojson $geoIntersects 问题:
It's working very well when my polygon is a square, or a rectangle, but I'm unable to get some results from a $geoIntersects request when my Polygon has crossing vertices, like this example:当我的多边形是正方形或矩形时,它工作得很好,但是当我的多边形有交叉顶点时,我无法从 $geoIntersects 请求中获得一些结果,如下例所示:

The polygon data looks like this:多边形数据如下所示:
{
"type": "Feature",
"properties": {
"shape": "Polygon"
},
"geometry": {
"type": "Polygon",
"coordinates": [
[
[-1.565584, 47.226352],
[-1.564704, 47.226927],
[-1.564093, 47.225616],
[-1.563138, 47.226374],
[-1.565584, 47.226352]
]
]
},
"id": "dda54a42-090b-46ea-9dd0-fdda6d240f90"
}
For this example, I need to know if the Polygon includes my Point coordinates.对于这个例子,我需要知道 Polygon 是否包含我的 Point 坐标。 This is my simple query:这是我的简单查询:
db.geojsondatas.find({
geometry: {
$geoIntersects: {
$geometry: {
type: "Point",
coordinates: [ -1.555638, 47.216245 ]
}
}
}
});
Anyone knows if there is a way to do this?任何人都知道是否有办法做到这一点?
Thanks by advance.提前谢谢。
Maybe try with JTS Topology Suite and investigate your polygon:也许尝试使用JTS 拓扑套件并调查您的多边形:
I don't think $geoIntersects
supports Self-intersecting polygon.我不认为$geoIntersects
支持自相交多边形。
