Open Vector Analysis
摘要
Vector data represent spatial objects and phenomena by modelling the geometry and the attribute. Vector data enable us to describe spatial distribution and analyze spatial patterns in the world. This chapter introduces the concept of the vector data model, and the vector processing and analysis functions. Several typical open-source GIS softwares are presented, including GRASS, QGIS, GeoDa, Whitebox GAT, gVSIG, and MapWindow. Exercises are provided to solve real-world problems.
