地理编码？将坐标列添加到点数据集中

Question

如果我有一个包含行业名称和所在城市的数据集，有没有办法可以从谷歌地图自动获取地址或坐标？我尝试询问 ChatGPt，后者告诉我使用 Geoocoding。

我需要在数据集中创建一个包含地址或坐标的列，以便我可以在地图上对它们进行地理定位。我只有城市栏。

示例：Smaltimento Rifiuti Ecoiso |那不勒斯。我需要另外两列，其中包含从 Google 地图获取的坐标，或另一列包含地址（第一列更好）

尝试获取 Google api

Answer 1

此代码使用 Google Places API 获取不同城市各个行业的地址和

Geolocation

（纬度和经度）。它迭代包含行业名称和城市的数据集，发出 API 请求来检索地点 ID 和详细信息，然后使用地址和位置信息记录结果。目标是使用 Google Places API 收集每个行业-城市对的地理数据

两个 Google API

您需要启用两个Google API 地点 API

地图 JavaScript API

您需要从您的Google帐户项目中复制API Key。

https://console.cloud.google.com/cloud-resource-manager

演示代码

此代码将解决您的问题。

另存为
