深圳海岸线修测及数据处理

深圳经济发展迅速,特别是沿岸段海岸线的开发与利用,使得部分海岸线变迁较快,依据实际现状对现今海岸线进行全面、系统的测量 、修正、补充、绘制和分析 ,确保海岸线的现势性具有重要意义 . 论文介绍深圳全市海岸线的定测以及海岸线两侧的地形测量方法,即采用GPS RTK 、GPS等方法进行全市现状海岸线定测工作,采用GPS动态测量(RTK)配合PDA方法对陆域方向300米、GPS配合测深仪采用无验潮测深法向海域方向500米进行 1 :2 000 水下地形测绘工作. 给出了海岸线数据转换、地形图转换 、陆域高程转换、水域高程转换等方法和结果,为今后的各项用海提供了科学、精准的海岸线数据.

Survey and Data Processing of Shenzhen Coastline

Shenzhen's economic development rapidly and , in particular , the development and utilization of coastal shoreline segments ,making some shoreline change rapidly .This study was based on the actual status of the coastline of Shenzhen today a comprehensive measurement system ,amend,supplement,drawing and analysis is important in ensuring that the coastline in terms of reality .This paper introduces the coastline on both sides of a given method of measuring and topographic survey of the city of Shenzhen coastline .That use of GPS RTK ,GPS and other methods to Shenzhen coastline fixed measurement work .And the use of GPS dynamic measurements (RTK) method with the PDA direction of land 300 meters,GPS with sounder use Tide sounding ,direction to the sea 500 meters at the beginning of 1:2000 Underwater Topo-graphic works .It also gives the coastline data conversion ,topographic maps ,land elevation conversion ,water elevation con-version methods and results ,the use of the sea for future decision-making provide a scientific ,accurate data shoreline .
