Surfer软件在疏浚水深测量中的应用

Application of surfer software in dredging depth measurement

航道疏浚施工中,如何用直观的图形来反映原地形地貌和后期的地形变化情况,用以控制施工进度和质量,是施工过程的重点和难点。以CASS数字测图所绘制平面二维图形为基础,结合Surfer软件所绘三维图形,对水底地形进行分析。该方法充分发挥三维模型在水深测量后期绘图中的优越性,取得了令人满意的效果。

How to use the intuitive graphics to reflect the original landform and topography and alteration to control construction progress and quality in construction of waterway dredging is important and difficult in the construction process. Based on a 2D graphics by CASS digital, combined a 3D graphics by Surfer software, the underwater topography is analyzed.The method can fully develop the superiority of 3D model in post bathymetric surveying and mapping, and the satisfactory result is achieved.
