Design and Realization of a Geospatial Data Sharing Model

ZHANG Wei,CUI Tie-jun,GUO Li,YAO Hui-min(S/M College,Information Engineering University,Zhengzhou 450052,China)  
Aiming at the inconsistency of the people's urgent requirement to multisource data with the geographical space data has different sources,the article analyzed the advantages and disadvantages of the existing data sharing methods.From the perspective of multisource data sharing,an object-oriented unified data model was designed,and carried on elaborating explanation on the conversion from data formats which are in usually used to the unified data model format.
