Thiessen Irrigation Weighting QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Computes the area-weighted average of point station data (rainfall, irrigation water requirement, discharge, etc.) using the Thiessen (Voronoi) polygon method.
About
This plugin generates Thiessen polygons (a Voronoi diagram) from point data such as meteorological or irrigation stations, optionally clips them to an irrigation area boundary, and computes the area-weighted average value (e.g. area-weighted average rainfall or irrigation water requirement) based on each polygon's area. AREA_HA, AREA_PCT and WEIGHT_CONTRIB fields are added to the result layer.
