如何对行政区和邮政区域进行地理编码

Geocode API 允许您使用查询文本输入对地理区域进行地理编码，例如国家、地区（州或省）或城市的名称。API 响应包括位置详细信息，例如地理坐标、地图可视化的边界框以及表示结果与查询相关性的匹配分数。

潜在用例

• 获取行政区域的坐标：在其他地方使用坐标作为偏差位置或中心 APIs。

• 在@@ 地图上可视化信息：地理编码坐标可用于在地图上直观地显示数据。

对邮政编码进行地理编码

您可以对邮政编码进行地理编码。IncludePlaceTypes与一起使用["PostalCode"]可获得更精确的结果。

Sample request

{
  "QueryText": "800006",
  "Filter": { "IncludePlaceTypes": ["PostalCode"] }
}

Sample response

{
    "ResultItems": [
        {
            "PlaceId": "<Redacted>",
            "PlaceType": "PostalCodeArea",
            "Title": "800006, Patna, Bihar, India",
            "Address": {
                "Label": "800006, Patna, Bihar, India",
                "Country": {
                    "Code2": "IN",
                    "Code3": "IND",
                    "Name": "India"
                },
                "Region": {
                    "Code": "BR",
                    "Name": "Bihar"
                },
                "SubRegion": { "Name": "Patna" },
                "Locality": "Patna",
                "PostalCode": "800006"
            },
            "Position": [85.18048, 25.61532],
            "MapView": [85.16599, 25.60054, 85.19103, 25.6221],
            "MatchScores": {
                "Overall": 1,
                "Components": {
                    "Address": { "PostalCode": 1 }
                }
            }
        }
    ]
}

开发者小贴士

使用IncludeCountries和之类的过滤器IncludePlaceTypes可获得更有针对性的结果。例如，为了确保来自美国温哥华的结果，请设置"IncludeCountries": ["USA"]。有关更多详细信息，请参阅 。

{
  "QueryText": "Vancouver",
  "Filter": { "IncludeCountries": ["USA"] }
