The Conne River watershed is dominated by wetlands that provide valuable ecosystem services, including contributing to the survivability and propagation of Atlantic salmon, an important subsistence species that has shown a dramatic decline over the past 30 years. To better understand and improve the management of the watershed, and in turn, the Atlantic salmon, a wetland inventory of the area is developed using advanced remote sensing methods including field-collected data, object-based image analysis of Sentinel-1, Sentinel-2, and digital elevation model Earth observation data. The resulting classification maps consisted of bog, fen, swamp, marsh, and open water wetlands with an overall accuracy of 92% and a kappa coefficient of 0.916. Among wetland classes, user and producer accuracies range between 84% and 100%. Results show the dominance of peatland wetlands such as bog and fen, and the relative rareness of marsh wetlands.

加拿大纽芬兰康纳河基于对象的随机森林湿地制图

康恩河流域以湿地为主，这些湿地提供有价值的生态系统服务，包括促进大西洋鲑鱼的生存和繁殖，大西洋鲑鱼是一种重要的生存物种，在过去 30 年中急剧下降。为了更好地了解和改善流域的管理，进而改善大西洋鲑鱼的管理，该地区的湿地清单是使用先进的遥感方法开发的，包括现场收集的数据、Sentinel-1 的基于对象的图像分析、Sentinel- 2、数字高程模型地球观测数据。所得分类图由沼泽、沼泽、沼泽和开阔水域湿地组成，总体准确度为 92%，kappa 系数为 0.916。在湿地类别中，用户和生产者的准确率在 84% 到 100% 之间。
