【摘要】:通過以GPS載波相位差分定位技術(shù)和回聲測深儀等組成的三維數(shù)據(jù)自動采集系統(tǒng),按照規(guī)定的測線,快速準確地采集高密度、高精度水下地形數(shù)據(jù),獲取水底測點平面和深度信息,利用以ArcGIS為平臺的數(shù)據(jù)處理編輯軟件,制作水下地形圖、計算庫容、生成庫容曲線,并與初設庫容曲線進行復核分析,為探查泥沙淤積對庫容的影響、節(jié)能增效提供詳實可靠的基礎數(shù)據(jù)。
[Abstract]:Based on the GPS carrier phase differential positioning technology and echo sounder, a 3D data acquisition system is developed to collect high-density and high-precision underwater terrain data quickly and accurately according to the prescribed line. The data processing and editing software based on ArcGIS is used to make the underwater topographic map, to calculate the storage capacity, to generate the reservoir capacity curve, and to review and analyze it with the initial reservoir capacity curve, and obtain the plane and depth information of the measuring points under the water, and make use of the data processing and editing software based on ArcGIS as the platform. In order to investigate the effect of siltation on reservoir capacity, detailed and reliable basic data are provided for energy saving and efficiency increasing.
