ee.Geometry.Rectangle.closestPoint
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。
返回右侧输入中与左侧输入最接近的点。如果任一输入为空,则返回 null。如果两个输入都是无界限的,则返回任意点。如果一个输入是无界的,则返回有界输入中的任意点。
用法 | 返回 |
---|
Rectangle.closestPoint(right, maxError, proj) | 对象 |
参数 | 类型 | 详细信息 |

此:left | 几何图形 | 用作运算左操作数的几何图形。 |
right | 几何图形 | 用作相应运算的右操作数的几何图形。 |
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 | 执行操作的投影。如果未指定,则操作将在球面坐标系中执行,并且球面上的直线距离将以米为单位。 |
