| Abstract:The main research achievements made from 1998 to 2000 for the project "The Share and Contrast Research of the Deep Geophysical Probing Data" are reported in this paper: 1 on the basis of analyzing the distribution and store conditions of the data, the dispersed data were rescued and collected according to technological regulations of the database and were input into the database after being arranged; 859 km deep seismic reflection profiles, 13 390 km profiles of deep seismic sounding, 5150 km Magnetotelluric Sounding data of 245 sites, 2 210 km Broadband Digital Seismographic Survey data of 44 GB, 839 sites of geothermal flow values and 19 346 km deep gravity and deep magnetic profile data collected on the scales of 1∶500 000 and 1∶1 000 000, were all input in the database; totally 146 CDs were made; the collected data possess about 92 percent of all the data; 2 the technologic regulations of the database in relation to seven speciality methods were studied; 3 the data normal formats of seven specialty methods were built, regulations and normalization of the data were preliminary realized, the technological preparation was provided for rescue and collection of data scattered in various units and individual persons as well as for inputting them into database; 4 the transition between different data media and data formats were realized; 5 the advanced system softwares, such as Access 97,VB6 , were used; the sub database system of seven specialties, way of data share, the sub system of CD database, the total management system of the database and graph database of geoscience digital transects were studied and established; some other advanced softwares, such as GIS, MAPGIS, were also used and developed in the process of the research,which help to combine the computer technology with the method and theory of the specialty so as to realize the preservation and polyfunctional search of the data rapidly and easily; 6 the principles of the data share were sought after and investigated with reference to experience gained both at home and abroad; an doable scheme(third manuscript) for data share adapted to the conditions of the Ministry of Land and Resources was proposed, which can carry forward the work of data share in the deep geophysical probing. |
