| 摘要: |
| 广西1:5万数字地质图空间数据库质量控制内容主要包括数据源、MAPGIS数据和元数据3个部分,在空间数据库建库过程应该从空间数据质量监控、数据库质量检查、质量监控制度落实3个方面进行质量监控,把数据质量控制在数据库建库的各个阶段,尽量减小人为误差,就能提高空间数据库的质量。 |

| Abstract: |
| Take 1:50000 geologic maps as an example, the content of monitoring and controlling spatial data quality is the source of database, MAPGIS database and metadata database. During the space database construction, the quality control of space data, the quality investigation of database and the policy of quality control should be monitored to improved database quality and minimize the man-made errors. |
