Analytical Protocols for Hydrological Vulnerability Assessment and BMP Targeting in the Cannonsville Watershed

Shared repository for data processing, analysis, modeling, and visualization

The live site is deployed at https://elliemadsen.net/ccsr-watershed-gis/visualization/index.html

Contributing

• Put raw and processed data files in data/
• Put scripts in data_processing/
• Put web viz in visualization/
• Document your work in README files within subdirectories
  • Include libraries, dependencies, methods, metadata (resolution, year, attributes, etc)
• Follow the established naming convention “variable_stage_resolution.ext"
• Use EPSG:32618 (WGS 84 / UTM zone 18N) for projection
• For large files, either add to LFS (.gitattributes) or .gitignore

Directory Structure

ccsr-watershed-gis/
├── data/                      # All raw and processed data files
├── data_processing/           # All processing scripts
└── visualization/             # Web-based visualization tools

Where possible, use the same sub-directory structure for data and data processing. E.g. the script and README in data_processing/precipitation/ refer to data/precipitation, and so on.
