mongodb - 如何将 Geojson 文件导入 MongoDB

Question

由于 Geojson 是实际的 json，我想我可以使用 mongoimport 将数据从 .geojson 文件加载到我的 MongoDB 数据库中。

但我收到以下错误:

exception:BSON representation of supplied JSON is too large: code FailedToParse: FailedToParse: Expecting '{': offset:0

文件大小为 25MB，这是其中的一个片段:

{
"type": "FeatureCollection",
"features": [
{
    "type": "Feature",
    "id": "node/2661561690",
    "properties": {
        "timestamp": "2014-02-08T17:58:24Z",
        "version": "1",
        "changeset": "20451306",
        "user": "Schandlers",
        "uid": "51690",
        "natural": "tree",
        "id": "node/2661561690"
    },
    "geometry": {
        "type": "Point",
        "coordinates": [
            -66.9162255,
            10.5056439
        ]
    }
},
// ... Omitted data
{
    "type": "Feature",
    "id": "node/2664472516",
    "properties": {
        "timestamp": "2014-02-10T04:27:30Z",

        "shop": "car_parts",

    },
    "geometry": {
        "type": "Point",
        "coordinates": [
            -66.9388903,
            10.4833647
        ]
    }
}
]
}

下载jq (它是类似于 sed 的程序，但用于 JSON)

然后运行:

jq --compact-output ".features"input.geojson > output.geojson

然后

mongoimport --db dbname -c collectionname --file "output.geojson"--jsonArray
