海洋遥感动态监测场景舟山市海岸线岛屿变化统计数据

该数据为二次加工数据，主要是以13-18年舟山海域遥感数据为基础，运用海岸线识别与提取模型和海岸线动态变化检测算法，实现各岛屿海岸线描绘和动态变化情况分析，数据可用于岛屿岸线变化情况统计分析展示及科学研究等场景。依托13-18年舟山海域遥感影像数据，构建海岸线识别与提取模型和海岸线动态变化检测模型，接入遥感影像（多光谱、微波）数据，获取海岸线信息，描绘舟山海岸线的几何轮廓和长度并通过多时相、多源遥感影像自动配准，获取海岸线的动态变化，生成不同时间段内的海岸线空间分布情况。

This is a secondary processed dataset primarily based on remote sensing data of the Zhoushan sea area from 2013 to 2018. By applying coastline recognition and extraction models and coastline dynamic change detection algorithms, it enables the delineation of coastlines of various islands and the analysis of their dynamic changes. The dataset is applicable to scenarios including statistical analysis and display of island coastline changes, as well as scientific research.

Constructed based on remote sensing image data of the Zhoushan sea area from 2013 to 2018, the coastline recognition and extraction model and coastline dynamic change detection model are developed. Remote sensing image data (multispectral and microwave) are accessed to obtain coastline information, based on which the geometric contours and lengths of the Zhoushan coastlines are delineated. Through automatic registration of multi-temporal and multi-source remote sensing images, dynamic changes of the coastlines are captured, and the spatial distribution of coastlines across different time periods is generated.
