Javascript 使用mongoose在mongoDB中存储可查询的GeoJson

因此，我试图能够查询到我的数据库，查找大型GeoJson文件的指定部分。原始文件的格式如下：

{
    "type": "FeatureCollection",
    "features": [{
            "type": "Feature",
            "properties": {
                "GEO_ID": "xxxxdhuxxx",
                "STATE": "01",
                "COUNTY": "029",
                "NAME": "Cleburne",
                "LSAD": "County",
                "CENSUSAREA": 560.100000
            },
            "geometry": {
                "type": "Polygon",
                "coordinates": [
                    [
                        [-85.388717, 33.913044],
                        [-85.380885, 33.873508]
                    ]
                ]
            }
        },
        {
            "type": "Feature",
            "properties": {
                "GEO_ID": "xxxxuiuyxxx",
                "STATE": "01",
                "COUNTY": "031",
                "NAME": "Coffee",
                "LSAD": "County",
                "CENSUSAREA": 678.972000
            },
            "geometry": {
                "type": "Polygon",
                "coordinates": [
                    [
                        [-86.030441, 31.618939],
                        [-86.004085, 31.619067],
                        [-85.999948, 31.619311],
                        [-85.980098, 31.619189],
                        [-85.926702, 31.618966],
                        [-86.030441, 31.618939]
                    ]
                ]
            }
        }
    ]
}

我当前的Mongoose模式是一个嵌套模式，其形式如下： GeoJson.model.js

`var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var Features = require('./Feature.model.js')

//Example schema with possible input types.
var GeoJsonSchema = new Schema({
"type": { "type": String },
"features": [Features]
  });`

和Feature.model.js

`var mongoose = require('mongoose');
var Schema = mongoose.Schema;


var FeatureSchema = new Schema({
"type": { "type": String},
"properties": {
  "GEO_ID": String,
  "STATE": String,
  "COUNTY": String,
  "NAME": String,
  "LSAD": String,
  "CENSUSAREA": Number
},
"geometry": {
  "type": { "type": String },
  "coordinates": []
}
  });


module.exports = mongoose.model('Feature', FeatureSchema);`

我不断得到验证错误，所以有些东西是错误的，但我就是不能发现它。有什么想法吗？

手册中列出了所有支持的类型<代码>功能集合不在支持的类型中。您可以使用

GeometryCollection

，或者只是将这些文档建模为普通MongoDB集合中的单个文档。相关：带有两个点的多边形看起来可疑。格式化的json更容易阅读。
