R d V i bl Random Variable Motivation • Classic Data  Classic Statistics Classic Data  Classic Statistics – iid: independent identically distributed rv. • Spatial Data  Spatial Statistics – spatially correlated data spatially correlated data – spatial heterogeneity – one realization 王劲峰等. 2006. 空间分析. 北京: 科学出版社

Motivation Objects & Spatial Tools Objects & Spatial Tools • Spatial objects: human economy land water climate • Spatial objects: human, economy, land, water, climate • Spatial Phenomena: distribution & movement Objective Tools Map GIS Display Display *** *** Enquiry *** P ttPatterns ** Determinants Simulation & Prediction Impact & Control *** *** * * *** excellent; ** good; * fine Spatial Analysis *** *** *** ***
