ee.Geometry.Point.coveringGrid
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。
返回覆盖相应几何图形的一系列要素，其中每个要素都是由指定投影定义的网格中的一个矩形。
| 用法 | 返回 |
|---|
Point.coveringGrid(proj, scale) | FeatureCollection |
| 参数 | 类型 | 详细信息 |
|---|
此：geometry | 几何图形 | 结果是与相应区域相交的网格单元。 |
proj | 投影 | 用于构建网格的投影。为与“geometry”相交的每个网格单元生成一个特征，其中单元格角位于投影中的整数值位置。如果投影按米缩放，则点将位于真实比例点处相应大小的网格上。 |
scale | 浮点数，默认值：null | 如果提供，则替换投影的缩放比例。如果投影尚未缩放，则可能需要此参数。 |
