We explored the possibilities of thematic classification in the powerful and complex software ArcGIS Pro;we presented the methodology used in a detailed way that allows others with minimal knowledge of GIS to reproduce the classification process without having to decipher the specifics of the software. The classification implemented used ground truth from four classes related to the macro-occupations of the area. In a first phase we explore the standard algorithms with object-based capabilities, like K-Nearest Neighbor, Random Trees Forest and Support Vector Machine, and in a second phase we proceed to test three deep learning classifiers that provide semantic segmentation: a U-Net configuration, a Pyramid Scene Parsing Network and DeepLabV3. The resulting classifications were quantitatively evaluated with a set of 500 control points in a test area of 37,500 × 12,500 pixels, using confusion matrices and resorting to Cohen’s kappa statistic and the concept of global accuracy, achieving a Kappa in the range [0.72, 0.81] and a global accuracy between 88.9% and 92.9%;the option U-Net had the most interesting results. This work establishes a methodology to provide a baseline for assessing future changes in the distribution of Sado estuarine habitats, which can be replicated in other wetland ecosystems for conservation and management purposes.关键词：ESTUARY SEGMENTATION 潮滩泥沙抗侵能力的微生物作用研究综述 2024年 关键词：微生物作用 灌河口潮间带大型底栖动物群落结构 2024年 关键词：潮间带 大型底栖动物 群落结构 基于无人机摄影测量的潮间带单波束测深空间插值精度评估 2024年 关键词：单波束测深 无人机 潮间带 2种贝类鳃暴露于潮间带原油污染的氧化应激效应 2024年 关键词：缢蛏 泥蚶 潮间带 原油污染 生物监测 三亚小东海海域潮间带大型底栖动物资源调查与分析 2024年 关键词：潮间带 大型底栖动物 洋山港海域码头人工潮间带大型底栖无脊椎动物群落变化 2024年 关键词：洋山港 码头 大型底栖无脊椎动物 中国海岸潮间带沙坝概查:地貌特征与形成条件 2024年 关键词：地貌特征 沉积动力环境 中国海岸 春、秋季灌河口潮间带大型底栖动物群落结构特征 2024年 关键词：潮间带 大型底栖动物 群落结构
