Greenland-wide proglacial rivers and lakes

This repository provides the code and datasets corresponding to the manuscript "Satellite mapping and hydrographic characterization of Greenland-wide proglacial rivers and lakes". Detailed discriptions are provided below.Folder "datasets_proglaical"Greenland_proglacial_river_network: Proglacial river networks mapped from Sentinel-2 imagery.Greenland_proglacial_lake_3classes_region: Proglacial lakes mapped from Sentinel-2 imagery, including pathway lakes, ice-marginal lakes and isolated lakes.River_sample_points_of_proglacial_Greenland: Proglacial river width sampling points. The attribute table provides river width (width), braiding index (BraidCount), and stream order (sorder).Greenland_proglacial_DEM_modeled_drainage_network: Proglacial drainage networks derived from Copernicus DEM.Greenland_proglacial_land_catchment: Supraglacial-proglacial catchments and proglacial catchments.Greenland_proglacial_outlets: The outlets of supraglacial-proglacial catchments and proglacial catchments.Greenland_marine-terminating_glacier_catchment: Marine-terminating catchments in Greenland.CodesCode01_Detect_pathway_lakes_using_width_points: A Jupyter Notebook for pathway lake detection. Input data must include river width, braiding index, individual profile identification, and along-stream distance.Code02_Greenland_proglacial_rivers_and_lakes: A Jupyter Notebook to analyze proglacial rivers and lakes, reproducing most of the tables and figures presented in the manuscript using the provided datasets.本仓库提供了与学术论文《格陵兰全域冰前河流与湖泊的卫星制图及水文特征表征》相对应的代码与数据集，下文将给出详细说明。 ### 「datasets_proglaical」文件夹 1. `Greenland_proglacial_river_network`：基于哨兵-2（Sentinel-2）影像绘制的冰前河网。 2. `Greenland_proglacial_lake_3classes_region`：基于哨兵-2（Sentinel-2）影像绘制的冰前湖泊，涵盖路径湖（pathway lakes）、冰缘湖（ice-marginal lakes）与孤立湖（isolated lakes）三类。 3. `River_sample_points_of_proglacial_Greenland`：格陵兰冰前河流宽度采样点，其属性表包含河宽（width）、辫状指数（BraidCount）以及河流级别（sorder）。 4. `Greenland_proglacial_DEM_modeled_drainage_network`：基于哥白尼数字高程模型（Copernicus DEM）推导得到的冰前排水网络。 5. `Greenland_proglacial_land_catchment`：表碛-冰前汇水区与冰前汇水区。 6. `Greenland_proglacial_outlets`：表碛-冰前汇水区与冰前汇水区的出水口。 7. `Greenland_marine-terminating_glacier_catchment`：格陵兰海洋终止型冰川汇水区。 ### 代码 1. `Code01_Detect_pathway_lakes_using_width_points`：一款用于路径湖检测的Jupyter Notebook，其输入数据需包含河宽、辫状指数、单个剖面标识以及沿程距离。 2. `Code02_Greenland_proglacial_rivers_and_lakes`：一款用于分析冰前河流与湖泊的Jupyter Notebook，可利用本仓库提供的数据集复现该论文中绝大多数表格与配图。
