摘要
随着测绘技术的进步,使水下地形测量中水位的施测变得简单;而随着绘图软件的不断完善,使内业人员从繁重的水位计算中解放出来,可以从图面上将水深改成高程,提高了工效。本文针对河流水下地形测量中水位的应用给出了现阶段图上处理过程。
Along with progress of survey technology,it becomes simply to survey water-level in the underwater topography. And with the developing of mapping software, peoples are getting rid of the arduous water - level computation, and can turn the depth to the elevation on screen directly to increase efficiency. This paper made the treating processes for water - level of the underwater topography at present.
