地理交集内合并

支持于: 批处理, 流处理

内合并左侧和右侧数据集基于输入几何是否重叠。结果中仅包括接触的几何。

变换类别: 地理空间, 合并

声明的参数

  • 左侧要选择的列的条件 - 将测试左侧输入架构中的所有列以查看它们是否符合此条件。如果符合，列将被选入输出。
    ColumnPredicate
  • 右侧要选择的列的条件 - 将测试右侧输入架构中的所有列以查看它们是否符合此条件。如果符合，列将被选入输出。
    ColumnPredicate
  • 合并键 - 用于合并的左侧和右侧输入的GeoJSON列。
    Tuple<Column<Geometry>, Column<Geometry>>
  • 左侧数据集 - 用于合并的左侧数据集。
    Table
  • 右侧数据集 - 用于合并的右侧数据集。
    Table
  • 非必填 右侧列的前缀 - 添加到右侧所有列的前缀。
    Literal<字符串>
