A QGIS plugin for planning surface drainage water management like Keyline-Design.
It automates the extraction of main valleys and ridges, creates off-contour line and supports creating Keyline Designs and other water-retention planning measures. The tool can also be used for other tasks, such as planning the location and alignment of paths and roads.
DOCUMENTATION: Detailed INSTALLATION MANUAL and TUTORIAL GUIDES are available on the project homepage: https://github.com/wickit7/topo-drain-plugin
Core algorithms leverage whitebox_workflows as the runtime backend (Whitebox Geospatial Inc., Dr. John B. Lindsay: https://github.com/jblindsay/whitebox_next_gen).
It is recommended to install the "Whitebox Workflows for QGIS" plugin first.
This plugin requires several Python packages (numpy, shapely, pandas, geopandas, scipy, whitebox_workflows).
These packages are widely used in geospatial data processing, but may not all are included in default QGIS installations. See on github site for more informations! -> https://github.com/wickit7/topo-drain-plugin
