Example of Watershed Delineation and Map Visualization for the Data Processing Kernel in CyberGIS-Jupyter for Water (CJW)

These are examples to test Data Processing Kernel in CyberGIS-Jupyter for water.
The 1_watershed_delineation folder is an example of a watershed delineation which is the basic step to analyze an interesting watershed. We used GRASS GIS 7.8 version and shell script to apply GRASS GIS library.
The 2_map_visualization folder is an example of an interactive map visualization which is the high-level visualization using PyViz tools as post-processing of environmental modeling. For this example, we used the following PyViz tools:
- geopandas (https://geopandas.org/), cartopy (https://scitools.org.uk/cartopy/), geoviews (https://geoviews.org/), and holoviews (https://holoviews.org/)

本数据集旨在检验 CyberGIS-Jupyter 中的数据处理核心功能，针对水资源领域。1_watershed_delineation 文件夹展示了流域划分的实例，这是分析特定流域的基础步骤。本研究采用 GRASS GIS 7.8 版本及 shell 脚本执行 GRASS GIS 库的应用。2_map_visualization 文件夹则是一个交互式地图可视化的示例，该可视化属于高级层次，利用 PyViz 工具对环境模型进行后处理。本示例中，我们使用了以下 PyViz 工具：geopandas (https://geopandas.org/)、cartopy (https://scitools.org.uk/cartopy/)、geoviews (https://geoviews.org/) 和 holoviews (https://holoviews.org/).
