Seascape Character Areas

Seascape is defined as an area of sea, coastline or land, as perceived by people, whose character results from actions and Interactions of land with sea by natural and/or human factors. GIS datsets from varying disciplines were gathered and analysed — bathymetry, geology, habitats, archaeology, conservation designations, fisheries, energy — among others. Seascape Character Assessment boundaries were determined using a 1 Km inland buffer of the Osi 1:250,000 coastline. This was merged with the Maritime Boundary Irish Territorial Sea to 12 nm. Additional limits were applied using the Irish Exclusive Economic Zone Maritime Boundary and the outer boundaries of the Northern Ireland seascape Character Assessment (DAERA). GIS and visual analysis combined with field work determined the individual seascape character areas. A Baseline regional scale of 1:500,000 was used during analysis but final areas vary in scale from 1:100,000 to 1:800,000 Owing to local variations and nuances of seascape character. Analysis and mapping used QGIS v3.8 Regional Seascapes Character Assessment (2020) project was carried out by Minogue and Associates on behalf of the Marine Institute.海景（Seascape）被定义为人类感知范畴内的海域、海岸线或陆地区域，其特质由陆地与海洋在自然及/或人为因素作用下的互动过程共同塑造。本研究收集并分析了多学科的地理信息系统（Geographic Information System，GIS）数据集，涵盖水深测量、地质学、生境、考古学、保护区划、渔业、能源等多个领域。 海景特质评估（Seascape Character Assessment）边界以Osi 1:250,000比例尺海岸线向内陆延伸1公里的缓冲区为基准确定，随后将该缓冲区与爱尔兰领海12海里海事边界进行合并。额外边界则依据爱尔兰专属经济区海事边界以及北爱尔兰海景特质评估（Seascape Character Assessment，DAERA）的外围边界划定。结合地理信息系统分析、视觉分析与实地调研，最终划定各独立海景特质区域。分析阶段采用1:500,000的区域基准比例尺，但由于海景特质存在本地差异与细微特征，最终划定区域的比例尺介于1:100,000至1:800,000之间。分析与制图工作均采用QGIS v3.8软件完成。 本次《区域海景特质评估（Regional Seascapes Character Assessment，2020）》项目由Minogue and Associates受爱尔兰海洋研究所委托开展。
