ee.Geometry.MultiPoint.cutLines
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
通过将 LineString、MultiLineString 和 LinearRing 几何图形沿其长度切割成不超过指定距离的部分，将其转换为 MultiLineString。所有其他几何图形类型都将转换为空的 MultiLineString。
| 用法 | 返回 |
|---|
MultiPoint.cutLines(distances, maxError, proj) | 几何图形 |
| 参数 | 类型 | 详细信息 |
|---|
此：geometry | 几何图形 | 剪切相应几何图形的线条。 |
distances | 列表 | 沿每条 LineString 的距离，用于将该线切割成单独的片段，以指定投影的单位或米为单位（如果未指定投影）。 |
maxError | ErrorMargin，默认值：null | 执行任何必要的重新投影时可容忍的最大误差量。 |
proj | 投影，默认值：null | 结果和距离测量的投影，如果未指定，则为 EPSG:4326。 |
