基于多源数据的广西大陆海岸线变迁研究

The Research of Guangxi Continental Coastline - Changing Based on Multi - Source GIS Data

海岸线变迁是海岸信息动态变化研究的重要组成部分,为了能够更精确地获取海岸线空间变化和地理信息要素变化信息,需要基于多种数据源获得历史各个时相的海岸线数据,保证研究的准确性。广西大陆海岸线变迁研究中,采用了多个历史时相、多类型和多种数据格式的数据源,通过地理信息框架统一实现数据源融合统一,采用多种技术手段处理和提取海岸线空间位置信息与其他信息,采用多种手段统计和分析广西海岸线过去50年来的演变情况和未来发展趋势,为广西海岸的保护条件下利用提供了可靠材料。

The coastline-changing is one of the most important parts in coast variation research.To get the more accurate and plentiful GIS information of coastline-changing,it’s necessary to get he coastline data of different historical time from multi-source data.In the research of coastline-changing in Guangxi to get the situations and the regular patterns of coastline-changing in Guangxi,we use multi-historical times,different kinds and different formats GIS data to realize the merging of a standardized coordinate and framework,and use multi-ways to analyse the changing of coastline in Guangxi in the past 50 years.The results can be referred to protect and develop the coastline in Guangxi.
