基于VC 6.0平台的水准网平差数据库设计与实现

Design and realization of database for adjustment of leveling network on the basis of VC 6.0

为了适应现代工程需求,将某项目的水准网数据平差计算进行数据库设计,实现数据调用及读写、内业编程平差计算、精度评定、数据处理软件化自动化运行,提高数据处理和精度评定的效率,并实现高质量有效地管理水准测量数据,满足测绘专业工作人员的需要。通过数据库设计,合理地组织水准网数据库,经过高程控制网的数据估算和精度评定,达到高效解算的目的,可应用于实际工程中。

In order to meet the demand of modern engineering, the design is used in the standard networkdata of a certain project adjustment calculation of design and realization of database, the database and tabledesign, data calls and read and write, industry programming adjustment calculation, precision evaluation,realizes the data processing software of the automatic operation, improves the efficiency level network dataprocessing and precision evaluation, and to achieve a high quality and effective management of levelingdata, to meet the needs of professional surveying and mapping staff. Through the design, rationalorganization of leveling network database, through the elevation data to estimate and accuracy of controlnetwork, to achieve efficient solution, can be used in engineering practice.
