| Abstract: | Aiming at the actual demands of dynamic protracting and real time updating of geologic map in oilfield, we have studied the practical methods of protracting geologic map based on WebGIS. It realizes the dynamic connect of the figure and image data and the attribution data and provides the function of the view-query and interspace analysis in the interspace frame using the availabilitive mechanism of geographic information expression, management, query and analysis with MapX. The database of exploration and development in oil field is extended to database of GIS that can be regarded as bottom data in order to realize the dynamic generation and updating of various geologic maps under Internet/Intranet environment and to query and analyze for image using the own function of geographic information technology. It achieves better effect in the practical application. |
