摘要:

该文介绍了1∶1万基础地理信息数据库地形要素更新的作业方法和地形要素更新模式，数字线划图数据更新、等高线和高程点的更新、数据库构建、成果库更新等关键技术环节，工作中的注意事项和工作安排。结合实际工作经验，指出地形要素数据标准应进一步严格对照国家相关规范，综合考虑信息完整表达、符合使用习惯等因素，更好地满足应用和图面表达美观的制图数据标准。

Abstract:

In this paper, present condition of updating basic geographic information database with the scale of 1∶10000 in Shandong province has been introduced. The updating method and mode have been studied. Based on key technologies, such as digital line drawing data updating, contour line and elevation point updating, database construction, and result library updating, specific matters which should be paid more attention and work arrangements have been elaborated. Combined with actual work experience, specific requirements for updating terrain elements have been put forward. It is pointed out that the data standard of topographic elements should be further strictly compared to the relevant national standards. Information expression and use habits should be considered omprehensively in order to meet the demand of drawing standard graphic data.
