问题描述
由于Geojson是实际的json，所以我认为我可以使用mongoimport从.geojson文件将数据加载到我的MongoDB数据库中.
Since Geojson is actual json I thought i could to use mongoimport to load data into my MongoDB database from a .geojson file.
但是我遇到以下错误:
exception:BSON representation of supplied JSON is too large: code FailedToParse: FailedToParse: Expecting '{': offset:0
文件为25MB，它是其中的一部分:
The file is 25MB and this is a fragment of it:
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"id": "node/2661561690",
"properties": {
"timestamp": "2014-02-08T17:58:24Z",
"version": "1",
"changeset": "20451306",

},
"geometry": {
"type": "Point",
"coordinates": [
-66.9162255,
10.5056439
]
}
},
// ... Omitted data
{
"type": "Feature",
"id": "node/2664472516",
"properties": {

}
推荐答案
下载 jq (类似于sed的程序，但对于JSON)
Download jq (it's sed-like program but for JSON)
然后运行:
jq --compact-output ".features" input.geojson > output.geojson
然后
mongoimport --db dbname -c collectionname --file "output.geojson" --jsonArray
