Spatial data modeling for coalfield geological environment

Presented a study on the design and implementation of spatial data modeling and application in the spatial data organization and management of a coalfield geological environment database. Based on analysis of a number of existing data models and taking into account the unique data structure and characteristic, methodology and key techniques in the object-oriented spatial data modeling were proposed for the coalfield geological environment. The model building process was developed using object-oriented technology and the Unified Modeling Language (UML) on the platform of ESRI geodatabase data models. A case study of spatial data modeling in UML was presented with successful implementation in the spatial database of the coalfield geological environment. The model building and implementation provided an effective way of representing the complexity and specificity of coalfield geological environment spatial data and an integrated management of spatial and property data.
