如何验证Geojson中的属性密钥

how to validate properties key in a geojson(如何验证Geojson中的属性密钥)

问题描述

我想知道为什么下面发布的Geojson格式无效。我试图将它的数据可视化 http://geojson.io

但未显示任何内容。

Geojson

{
 "type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Polygon",
"coordinates": [
[
[[7.85563468082516,49.90287230375267],[7.855636808249913,49.902782379662085],[7.855776033932631,49.902783753651605],[7.855773906766568,49.902873677746555]]
]
]
},"properties": {"areaOfCoverage":"30"}},
}

推荐答案

试试：

{
  "type": "FeatureCollection",
  "features": [
    {
      "properties":{"areaOfCoverage":"30"},
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [
               7.85563468082516,
              49.90287230375267
            ],
            [
              7.855636808249913,
              49.902782379662085
            ],
            [
              7.855776033932631,
              49.902783753651605
            ],
            [
              7.85563468082516,
              49.90287230375267
            ]
          ]
        ]
      }
    }
  ]
}
