获取覆盖几何图形的H3索引

支持于: 批处理, 流式

将几何图形转换为特定分辨率的H3索引。分辨率必须在0到15之间（含）。对于多边形，支持三种转换：a) 完全覆盖多边形的H3索引，b) 完全包含于多边形内的H3索引，c) 其重心包含在多边形内的H3索引。当预期的H3索引数量超过700万时，返回null。

表达式类别: 地理空间

声明的参数

  • 覆盖类型 - 指定多边形的H3覆盖类型。
    枚举<Centroid, Inner, Outer>
  • 几何图形 - GeoJSON类型的多边形、线或点。
    表达式<Geometry>
  • 分辨率 - H3网格分辨率在0到15之间（含）。
    表达式<Byte | Integer | Long | Short>

输出类型: 数组<H3 索引>
