在哪里放置额外的 GeoJson 属性

Where to put extra GeoJson properties

我正在使用 GeoJson 格式为一个国家/地区创建地图,但我想知道在哪里放置额外的国家/地区信息,例如 NameCountry Code 和一些有用的信息。

我知道我们可以很容易地为特征(在我的例子中是区域数据)做到这一点,但是我可以在哪里放置国家/地区属性?

us.json

{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "properties": {
                "REGION_ID": 1,
                "REGION_NAME": "My First Region",
            },
            "geometry": {
                "type": "Polygon",
                "coordinates": [
                    [
                        [1.83, 15.93]
                    ],
                    ...
                ]
            }
        }
        ...
    ]
}

如果我将其插入 Mapbox geojsonhint,它不会显示任何错误:

{
    "type": "FeatureCollection",
    "properties": {
        "name": "United states of America"  
    },
    "features": [
        {
            "type": "Feature",
            "properties": {
                "REGION_ID": 1,
                "REGION_NAME": "My First Region"
            },
            "geometry": {
                "type": "Polygon",
                "coordinates": [
                    [
                        [1.83, 15.93], [1.83, 15.93], [1.83, 15.93], [1.83, 15.93]
                    ]
                ]
            }
        }

    ]
}
