| 摘 要： | 空间数据库质量的优劣直接影响到GIS应用分析结果的准确性与可靠性.因此,质量控制是区域地质图数据库建设的内在要求,而由于所有的空间基础信息在产生时都存在误差,所以,空间数据库的质量控制必须严格贯彻在数据库建设流程的每一个环节.本文以1∶5万山东省区域地质图空间数据库的建设流程为例,通过对基于MAPGIS建设区域地质图空...

| Abstract: | The emphasis of Geological Map Spatial Database constructing is the quality control throughout each step.For the quality of the data directly affects the accuracy and reliability of the results of the analysis in using GIS,and for deviations exist objectively in all the basic spatial geological information,quality control is the inherent demand in constructing Geological Map Spatial Database.Through the analysis of quality problems which may arise from building of the regional geological map spatial database based on MapGIS,especially in the process of map pretreatment,digitization,vectorization,error correction,topological reconstruction,attribute input and projection transformation,the authors try to find the solutions and preventive measures,so as to implement the control of quality,most minimize the deviations of spatial data,improve the efficiency of mapping and precision of spatial data,and provide better service for the public application fields of spatial database,such as the constructing of national economy,the developing of regional planning and the protecting of geological environment. |
