GEN_MAT: A MATLAB‐based map generalization algorithm toolbox

Assistive tools are important for improving teaching and learning quality in courses that involve practical work. This article presents an overview of GEN_MAT, the first MATLAB-based map generalization algorithm toolbox. The toolbox provides 42 map generalization algorithms for aggregation, selective omission, simplification, smoothing, collapse, agglomeration, merging, dissolving, displacement, and typification. A beta test of the application of GEN_MAT in teaching and learning was conducted. Evaluations showed that GEN_MAT has positive effects on teaching and learning. Comparing tool-based and non-tool-based courses indicated that the experimental group performed better than the control group, and the two groups exhibited significant discrepancy (p<0.05) in confidence, awareness, skills and attitudes or behaviors.
