GeoJSON#

一种基于 JSON 的地理空间数据交换格式，它定义了几种类型 JSON 对象以及它们组合在一起的方法，以表示有关地理要素、属性和它们的空间范围的数据。

点#

{
    "type": "Point",
    "coordinates": [30, 10]
}

复合点

{
    "type": "MultiPoint",
    "coordinates": [
        [10, 40], [40, 30], [20, 20], [30, 10]
    ]
}

线#

{
    "type": "LineString",
    "coordinates": [
        [30, 10], [10, 30], [40, 40]
    ]
}

复合线

{
    "type": "MultiLineString",
    "coordinates": [
        [[10, 10], [20, 20], [10, 40]],
        [[40, 40], [30, 30], [40, 20], [30, 10]]
    ]
}

多边形#

多边形

{
    "type": "Polygon",
    "coordinates": [
        [[30, 10], [40, 40], [20, 40], [10, 20], [30, 10]]
    ]
}

空心多边形

{
    "type": "Polygon",
    "coordinates": [
        [[35, 10], [45, 45], [15, 40], [10, 20], [35, 10]],
        [[20, 30], [35, 35], [30, 20], [20, 30]]
    ]
}

复合多边形

{
    "type": "MultiPolygon",
    "coordinates": [
        [
            [[30, 20], [45, 40], [10, 40], [30, 20]]
        ],
        [
            [[15, 5], [40, 10], [10, 20], [5, 10], [15, 5]]
        ]
    ]
}

复合空心多边形

{
    "type": "MultiPolygon",
    "coordinates": [
        [
            [[40, 40], [20, 45], [45, 30], [40, 40]]
        ],
        [
            [[20, 35], [10, 30], [10, 10], [30, 5], [45, 20], [20, 35]],
            [[30, 20], [20, 15], [20, 25], [30, 20]]
        ]
    ]
}
