根据您的偏好保存内容并对其进行分类。
构建一个边为纬度和经度线的矩形。
结果是一个平面 WGS84 矩形。
如果(东经 - 西经)≥ 360,则经度范围将归一化为 -180 到 +180;否则,它们将被视为指定圆上的点(例如,东经可能在数值上小于西经)。
用法 | 返回 |

ee.Algorithms.GeometryConstructors.BBox(west, south, east, north) | 几何图形 |
参数 | 类型 | 详细信息 |
---|
west | 浮点数 | 最西侧的封闭经度。将调整为介于 -180 到 180 之间。 |
south | 浮点数 | 最南端的封闭纬度。如果小于 -90(南极),则会被视为 -90。 |
east | 浮点数 | 最东侧的封闭经度。 |
north | 浮点数 | 最北端的封闭纬度。如果大于 +90(北极),则会被视为 +90。 |
