如何对行政和邮政区域进行地理编码
地理编码 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、区域（州或省）或城市的名称。该 API 响应包含位置详细信息，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得分。
潜在使用案例
-
获取行政区域的坐标：在其他地点 API 中使用坐标作为偏差位置或中心。
-
在地图上直观显示信息：地理编码坐标可用于在地图上直观地显示数据。
示例
- Sample request
-
{ "QueryText": "Canada" } - Sample response
-
{ "ResultItems": [ { "PlaceId":"<Redacted>", "PlaceType": "Country", "Title": "Canada", "Address": { "Label": "Canada", "Country": { "Code2": "CA", "Code3": "CAN", "Name": "Canada" } }, "Position": [-75.69122, 45.42177], "MapView": [-141.00271, 41.67659, -52.61901, 83.11062], "MatchScores": { "Overall": 1, "Components": { "Address": { "Country": 1 } } } } ] } - cURL
-

-
aws geo-places geocode --key ${YourAPIKey} --query-text "Canada"
- Sample request
-
{ "QueryText": "BC" } - Sample response
-
{ "ResultItems": [ { "PlaceId": "<Redacted>", "PlaceType": "Region", "Title": "BC, Canada", "Address": { "Label": "BC, Canada", "Country": { "Code2": "CA", "Code3": "CAN", "Name": "Canada" }, "Region": { "Code": "BC", "Name": "British Columbia" } }, "Position": [-123.36445, 48.42854], "MapView": [-139.04941, 48.22478, -114.05201, 60.00043], "MatchScores": { "Overall": 1, "Components": { "Address": { "Region": 1 } } } } ] } - cURL

-
aws geo-places geocode --key ${YourAPIKey} --query-text "BC"
- Sample request
-
{ "QueryText": "Vancouver" } - Sample response
-
{ "ResultItems": [ { "PlaceId": "<Redacted>", "PlaceType": "Locality", "Title": "Vancouver, BC, Canada", "Address": { "Label": "Vancouver, BC, Canada", "Country": { "Code2": "CA", "Code3": "CAN", "Name": "Canada" }, "Region": { "Code": "BC", "Name": "British Columbia" }, "SubRegion": { "Name": "Metro Vancouver" }, "Locality": "Vancouver", "PostalCode": "V5Y" }, "Position": [-123.11336, 49.26038], "MapView": [-123.26754, 49.19891, -123.02301, 49.33557], "MatchScores": { "Overall": 1, "Components": { "Address": { "Locality": 1 } } } } ] } - cURL
-
curl --request POST \ --url 'https://places.geo.eu-central-1.amazonaws.com/v2/geocode?key=Your_Key' \ --header 'Content-Type: application/json' \ --data '{ "QueryText": "Vancouver" }' - AWS CLI
-
aws geo-places geocode --key ${YourAPIKey} --query-text "Vancouver"
您可以对邮政编码进行地理编码。将 IncludePlaceTypes 与 ["PostalCode"] 结合使用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 } } } } ] } - cURL
-
curl --request POST \ --url 'https://places.geo.eu-central-1.amazonaws.com/v2/geocode?key=Your_Key' \ --header 'Content-Type: application/json' \ --data '{ "QueryText": "800006", "Filter": { "IncludePlaceTypes": ["PostalCode"] } }' - AWS CLI
-
aws geo-places geocode --key ${YourAPIKey} --query-text "800006" --filter '{"IncludePlaceTypes": ["PostalCode"]}'
开发人员提示
使用 IncludeCountries 和 IncludePlaceTypes 之类的筛选条件可获得更有针对性的结果。例如，为确保结果来自美国的温哥华，请设置 "IncludeCountries": ["USA"]。有关更多详细信息，请参阅。
