Spatial data model lays a foundation for the spatial data to organize,express,analyze,process and apply.By analyzing the shortage of spatial vector description methods on factor,object-oriented vector model(OOVM)is put forward on the view of incorporate management,and model structure,describing method and managing model of spatial object are discussed.In order to manage spatial information in network environment,the model describes spatial information as spatial object whose ID,attribute,method are encapsulated.Taking company information management as an example,the paper designs organizing process of distributed spacial data on OOVM.The researches above provide a new way for construction and sharing of the spatial data.
