Salish Sea Bioregion Detailed Land Cover

2015 Detailed Land Cover for the Salish Sea Bioregion. Created for the Salish Sea Atlas. Detailed land cover classes for the Salish Sea Bioregion. Based on 30x30 meter Landsat imagery from 2015 (Canada) or 2016 (USA). This land cover classification was derived from the North American Land Change Monitoring System. Land cover classes were subset, combined, and renamed to create a simpler set of classes customized for this region. Some areas' land cover classes were manually modified based on comparison with USGS GAP land cover data and recent aerial imagery. Most of these manual modifications were along the coastline. This dataset still seems to under-represent intertidal mudflats compared with the GAP land cover classification. The dataset was clipped to the Salish Sea Bioregion boundary from the Salish Sea Atlas. All processing and analysis was completed using the NAD 83 UTM Zone 10N projection and coordinate system. This is a tile layer designed for cartographic purposes. You can also download a .TIFF version of the file for analysis purposes from the Salish Sea Atlas website.

2015年萨利希海生物区（Salish Sea Bioregion）精细土地覆盖数据集。本数据集专为萨利希海地图集（Salish Sea Atlas）打造，为萨利希海生物区提供精细土地覆盖分类结果。数据基于2015年（加拿大区域）或2016年（美国区域）的30×30米分辨率Landsat影像。本次土地覆盖分类源自北美土地变化监测系统（North American Land Change Monitoring System）。研究人员对原始土地覆盖类别进行了筛选、合并与重命名，以此构建适配该区域的简化分类体系。部分区域的土地覆盖类别经与美国地质调查局（USGS）GAP土地覆盖数据及最新航空影像比对后完成人工修正，此类修正大多集中于沿海岸线区域。相较于GAP土地覆盖分类产品，本数据集对潮间带泥滩的表征仍存在不足。数据集已基于萨利希海地图集提供的萨利希海生物区边界完成裁切。所有处理与分析均采用NAD 83 UTM 10N投影与坐标系完成。本数据集为面向制图需求设计的瓦片图层。用户亦可从萨利希海地图集官网下载该数据集的TIFF格式版本以用于分析工作。
