Abstract The multisource geographical data may correspond to the diversity of storage formats and, as a result, the storage formats fail to carry out relevant interoperation and spatial analysis, which hinders the information sharing. The authors have hence developed a model for transformation from the Excel data file to Shapefile vector files by virtue of a secondary development based on the ArcGIS Engine modules, which include file access, defining the spatial reference, transformation of spatial and attribute information. As a more visualized expression, this data management method has preliminarily filled the gap between various geographical data and provided the sharing or operating. At the same time, the exploitation right file transformation from Access to Excel and then to Shapefile formats has realized, which is also a transformed expression with the nature of non-destruction, dimensional reduction and visuality in comparison with that of the original files. The essence of this method lies in resolving the information as the record format into the spatial and attribute format. The former format means the superposition of exploitation layer and corresponding remote sensing image, and seamless connection exists between the latter (like mineral species, mining pattern etc.) and the former. On such a basis, the exploitation information of the present situation can be obtained, and the remote sensing monitoring of mineral resources can be carried out.
