海岸线遥感判绘与提取系统实现

本文基于Access构建了海岸线类型数据库和解译标志数据库,实现了现场照片、解译标志图片、文字等信息的统一存储;并充分顾及海岸线判绘与提取工作特点进行系统设计,开发了数据库管理、海岸线判绘、海岸线提取和制图表达等4个子系统,实现了海岸线的流程化提取与制图。该系统简单实用、针对性强,提高了作业效率和准确性,可服务于海岸线动态变化遥感监测和管理。

Realization of the system for coastline protraction and extraction

The paper constructed the coastline type database and interpreting marks database,so the photos,interpreting marks and characters could be uniformly stored using Access database.Based on C# and ArcGIS Engine,it designed the system according to the work characteristic,developed the subsystems of database management,coastline protraction,coastline extraction and mapping expression,and realized the flow of extraction and mapping for coastline.The system could be manipulated simply and practically,and improve the working efficiency and accuracy,serving for dynamic monitoring and management of the coastline.
