Satellite Derived Bathymetry(卫星测深)研究综述
Satellite Derived Bathymetry 卫星测深 - Bathymetry retrievals from 2D, multispectral imagery, referred to as Satellite‐Derived Bathymetry (SDB), afford the potential to obtain global, nearshore bathymetric data in optically clear waters. [1] Although many studies have been conducted on satellite derived bathymetry (SDB), previously used methods basically require supervised data for analysis, and cannot be used to analyze areas that are unreachable by boat or airplane. [2] In this study, a satellite derived bathymetry (SDB) map, considered suitable for shallow water, was created using random forests (RF) and multi-temporal satellite images from Google Earth Engine. [3] The results demonstrate that the satellite derived bathymetry is efficient for retrieving depths up to 10 m for coastal regions and up to 30 m for lake environment. [4] Untuk menyelesaikan masalah tersebut, Satellite Derived Bathymetry, sebuah teknologi pemetaan yang memperoleh data bathimetri dari citra satelit multispektral resolusi tinggi diterapkan. [5] Satellite derived bathymetry (SDB) enables rapid mapping of large coastal areas through measurement of optical penetration of the water column. [6] Satellite Derived Bathymetry (SDB) method uses satellite or other remote multispectral imagery for depth determination in very shallow coastal areas with clear waters. [7]从 2D、多光谱图像中检索水深，称为卫星测深 (SDB)，有可能在光学清澈的海水中获得全球近岸水深数据。 [1] 尽管已经对卫星测深（SDB）进行了许多研究，但以前使用的方法基本上需要有监督的数据进行分析，不能用于分析船只或飞机无法到达的区域。 [2] 在这项研究中，使用随机森林 (RF) 和来自 Google 地球引擎的多时相卫星图像创建了一张被认为适用于浅水区的卫星衍生测深 (SDB) 地图。 [3] 结果表明，卫星测深可有效检索沿海地区高达 10 m 的深度和湖泊环境高达 30 m 的深度。 [4] 为了解决这个问题，应用了卫星衍生测深，这是一种从高分辨率多光谱卫星图像中获取测深数据的测绘技术。 [5] 卫星测深 (SDB) 可以通过测量水柱的光学穿透力来快速绘制大片沿海地区的地图。 [6] 卫星测深 (SDB) 方法使用卫星或其他远程多光谱图像来确定具有清澈海水的非常浅的沿海地区的深度。 [7]
