Bivariate Mapping of Rainfall, Groundwater Level, and Landcover

Bivariate Mapping of Rainfall, Groundwater Level, and Landcover: This dataset contains a complete, reproducible workflow for spatial, bivariate analysis of rainfall, groundwater level, and landcover at the regional scale. All source code (R scripts) is organized for clarity, rigour, and cross-platform use following open science best practices. Raster datasets (GeoTIFFs), output maps, and derived tables are included, along with a README.md, LICENSE, and package-locked environment via renv for transparency. Key features: 1. Bivariate mapping of rainfall and groundwater using the biscale approach. 2. Landcover–groundwater relationships, including custom categorical–continuous legends. 3. All R code is well-commented, modular, and ready for use in teaching or derivative studies. 4. Scripted workflow ensures figures are fully reproducible from raw inputs. 5. Includes helper functions and robust error-handling for flexible adaptation. 6. Supplemented with detailed README and session information for review and provenance. Typical applications: Hydrological assessment, aquifer mapping, GIS education, reproducible environmental research.降雨、地下水位与土地覆被双变量制图： 本数据集包含一套完整且可复现的区域尺度降雨、地下水位与土地覆被空间双变量分析工作流。所有源代码（R脚本）均遵循开放科学最佳实践进行组织，兼顾清晰性、严谨性与跨平台可用性。数据集包含栅格数据集（GeoTIFF格式文件）、输出制图成果与衍生数据表，同时附带README.md文档、许可协议（LICENSE）以及通过renv构建的包锁定环境，以保障研究透明度。 核心特性： 1. 采用biscale方法开展降雨与地下水位的双变量制图 2. 涵盖土地覆被-地下水位关联分析，包含自定义的分类-连续型图例 3. 所有R脚本均附带详细注释、采用模块化设计，可直接用于教学或衍生研究 4. 脚本化工作流可确保从原始输入数据即可完整复现所有制图成果 5. 内置辅助函数与完善的错误处理机制，便于灵活适配不同应用场景 6. 附带详细的README文档与会话信息，便于成果审核与研究溯源 典型应用场景： 水文评估、含水层制图、GIS教学以及可复现的环境科学研究
