根据纬度、经度和半径获取附近的景点

Question

我想知道是否会有一些 API 或 Web 服务给出经度和纬度，给我返回附近景点名称的列表（可能是餐馆、酒店等）。我一直在搜索谷歌，但没有发现任何有趣的东西。返回 JSON 对象的东西会很棒;)

Answer 1

Koordinates 有一个用于任意空间数据集的 lat/lng 查询的 API。响应可以是 XML、JSON 或 JSONP。有关信息，请参阅此页面：

• http://support.koordinates.com/entries/20182948-vector-query

例如，此处列出的任何兴趣点 (POI) 图层都可以使用纬度、经度和搜索半径进行查询：

• http://koordinates.com/layers/category/poi/

您可以免费上传和使用自己的数据，因此如果您找到更适合您所在位置的数据集，也可以添加。

-- 编辑：示例，第一次评论后的更多信息--

对于古巴，您需要查找/创建自己的兴趣点数据集 - 例如，可能获取您所在地区的 OpenStreetMap 数据的子集。基本上，您需要找到/创建要上传的 Shapefile 点数据集。

完成此操作后，您就可以使用上面链接的矢量 API。例如，在新西兰，Zenbu 提供了一个很好的 POI 层：

• http://koordinates.com/layer/1225-everything-from-zenbuconz-2011-august/webservices/

使用矢量 API 抓取一定半径内的特征。例如。要在我的（粗略）位置一公里内找到 10 个最近的点，我可以点击这个端点（使用我为此答案生成的密钥。您可以免费创建自己的 API 密钥）：

• http://api.koordinates.com/api/vectorQuery.json?key=ee1b29272cb844eb86706dd0e3cd2cd2&layer=1225&x=174.7771167755127&y=-36.852496745107175&max_results=10&radius=1000&geometry=false&with_field_names=true

响应如下所示：
