目标

在本教程中，您将执行以下操作：

  • 使用地理空间分析函数将纬度和经度列转换为地理位置点
  • 运行绘制飓风路径的查询
  • 在 BigQuery 中将结果可视化
  • 在 BigQuery Geo Viz 中可视化您的结果

费用

BigQuery 是一款付费产品，本教程中涉及的操作将产生 BigQuery 使用费。BigQuery 提供一些有特定限额的免费资源。如需了解详情，请参阅 BigQuery 免费操作和免费层级。

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.
