Accuracy assessment done right — Olofsson, Pontius, and publication-ready reports in one click.
GeoAccuRate provides statistically rigorous accuracy assessment for land cover
and remote sensing classification validation in QGIS. It implements the area-weighted
estimation method of Olofsson et al. (2014), Pontius quantity and allocation
disagreement metrics, Wilson confidence intervals, and automated stratified random
sampling with sample size optimization. Generates publication-ready PDF reports with
confusion matrices (counts and row-normalized), per-class metrics, interpretation
notes, ISO 19157 quality element mapping, and auto-generated methods text with
citations. Designed for researchers, students, and agencies requiring reproducible
and defensible accuracy assessment without leaving QGIS.
