Salish Sea Archipelagos

Mainland and islands within the Salish Sea Bioregion with a database of island names, small island chain names, and larger archipelago names. Island names were derived from the British Columbia Freshwater Atlas or transcribed from Google Maps. Where no name could be find, the name field was left blank. Coastlines were defined using the Washington ShoreZone Shoreline and British Columbia Freshwater Atlas shoreline. ShoreZone was given precedence where the datasets overlapped. ShoreZone gaps like river mouths were bridged with a straight line. Shoreline line features were converted to polygons. Multipart polygons were split and inland islands were removed. The entire dataset was clipped to the Salish Sea Bioregion boundary. All processing and analysis was completed using the NAD 83 UTM Zone 10N projection and coordinate system.

本数据集涵盖萨利什海生物区（Salish Sea Bioregion）内的大陆与岛屿，并配套建立了包含岛屿名称、小型岛群名称及大型群岛名称的数据库。岛屿名称数据来源于不列颠哥伦比亚省淡水图集（British Columbia Freshwater Atlas），或从谷歌地图（Google Maps）转录得到；若无法获取目标名称，则对应名称字段留空。海岸线数据采用华盛顿岸带海岸线（Washington ShoreZone Shoreline）与不列颠哥伦比亚省淡水图集海岸线进行界定，当两份数据集存在重叠区域时，优先采用华盛顿岸带海岸线数据集。针对华盛顿岸带海岸线数据中的河口等空白区段，以直线进行补全衔接。将海岸线线状要素转换为面状要素，拆分多部件面要素并移除内陆岛屿，随后将整份数据集裁切至萨利什海生物区边界范围内。所有处理与分析工作均基于NAD 83 UTM Zone 10N投影坐标系完成。
