摘要
This paper introduces three type spatial data models(the feature model,field model and hybrid model)and their modeling methods.Three application cases are listed:(1)mineral resources evaluation mode;(2)city geological model;(3)underground water evaluation model.In mineral resources evaluation mode the entity model and field model was integrated,three-dimensional entity model was used to display and retrieval,field model was used in reserve estimation and mineralization distribution prediction.In city geological model DEM modeling method was used to stratified geological;bodies in engineering geology.In underground water evaluation model hydrogeological sections are the main data source and hydrogeological borehole data,contour lines of aquifer group bottom depths the constraints.
