地址描述符请求和响应

地址描述符包含其他信息,可帮助您使用地标和区域描述地点。请查看地址描述符演示 来探索这项功能

其他参数

您可以使用 extra_computations 参数启用地址描述符。在地理编码请求中包含 extra_computations=ADDRESS_DESCRIPTORS反向地理编码请求地点地理编码请求 在响应中接收地址描述符。

地理编码示例

以下查询包含了德里某个地点的地址:

https://maps.googleapis.com/maps/api/geocode/json?address=4118,+Kalan+Mehal+Chandni+Chowk,+New+Delhi&extra_computations=ADDRESS_DESCRIPTORS&key=YOUR_API_KEY

地点地理编码示例

以下查询包含了德里某个地点的地点 ID:

https://maps.googleapis.com/maps/api/geocode/json?place_id=ChIJyxAX8Bj9DDkRgBfAnBYa66Q&extra_computations=ADDRESS_DESCRIPTORS&key=YOUR_API_KEY

反向地理编码示例

以下查询包含了德里某个位置的纬度/经度值:

https://maps.googleapis.com/maps/api/geocode/json?latlng=28.640964,77.235875&extra_computations=ADDRESS_DESCRIPTORS&key=YOUR_API_KEY

每个 address_descriptor 对象中都有两个数组:landmarksareaslandmarks 数组最多包含 5 个结果,这些结果会按相关性排序,并考虑与请求的坐标的距离、地标的普及程度和可见性。每个地标结果都包含 以下值:

  • place_id 是地标结果的地点 ID。查看地点 ID 概览
  • display_name 是地标的显示名称,包含 language_codetext
  • straight_line_distance_meters 表示输入坐标和地标结果之间的点对点距离(以米为单位)。
  • travel_distance_meters 是输入坐标与地图注点结果之间通过道路网络(忽略道路限制)行驶的距离(以米为单位)。
  • spatial_relationship 是输入坐标与地标结果之间的估算关系:
    • 如果不符合上述任何情况,则默认关系为 "NEAR"
    • 当输入坐标包含在与地标关联的结构边界内时,值为 "WITHIN"
    • 如果输入坐标与地标或地标的接入点直接相邻,则为 "BESIDE"
    • "ACROSS_THE_ROAD"(当输入坐标与路线另一侧的地标直接相反时)。
    • 如果输入坐标与地标位于同一路线上,但不是 "BESIDES""ACROSS_THE_ROAD",则为 "DOWN_THE_ROAD"
    • "AROUND_THE_CORNER"(当输入坐标沿着垂直路线作为地标时)。
    • 当输入坐标在空间上靠近地标,但远离其接入点时,使用 "BEHIND"
  • types 是地标的地点类型

areas 对象最多包含 3 个回答,并且仅限于代表小区域的地点,例如社区、子区域和大型建筑群。包含请求坐标的区域会先列出,并按面积从小到大排序。每个 areas 结果都包含以下值:

  • place_id 是相应区域结果的地点 ID。请参阅地点 ID 概览
  • display_name 是相应区域的显示名称,包含 language_codetext
  • containment 是输入坐标与区域结果之间的估计包含关系:
    • 当以下项均不适用时,"NEAR" 是默认关系。
    • 如果输入坐标接近区域中心,则为 "WITHIN"
    • 当输入坐标接近相应区域边缘时,返回 "OUTSKIRTS"
