The Design And Realization Of The Cross Section Metrical Data Processing System

The 21st century is the rapid development century with science and technology changes every day. The science and technology becomes the most important resource and impelling force for the economic development. As an engineering construction leading discipline, survey profession response more intense. Along with the survey technology's development, computer is getting more and more popular in modern survey science application, which already penetrated into from the fundamental research to the actual production aspects. Because of its rapid, accurate and convenient, computer has brought the enormous convenience for the survey study fundamental research and the production application.Using computer program processing metrical data is not only convenient and rapid, but also accurate and repeatable. Therefore, the survey people more and more pay attention to using the union survey specialized knowledge, the comprehensive utilization computer programming language and the database handling technology as well as AutoCAD the re-development technologies to carry on the processing magnanimous survey data.This article has developed a set of more compatible and more automatic high cross section metrical data processing system by using the coordinates system, the VB visualization programming technology, the data bank technology, the AutoCAD technology and so on. This system changed the traditional manual processing cross section metrical data work pattern. The system has played the extremely vital role in the divert water from the south to the north project, Jiaodong adjusted the water project, east the river bank Shuhe River Si River and the flood the accent go south state-level priority projects and so on. The system has proved to be effective and received consistent high praise of the concerned Brother unit and technical experts.This paper mostly engaged in researches and design as follows:1. Elaborated the survey coordinates system knowledge which the system must rely on. Explored system's main programming language VB technical knowledge, programming technology, data bank technology as well as AutoCAD technology and re-development;2. Exploring this system's original intention , its design concept and system's system design portal frame construction;3. Elaborated this system's detailed function in realization;4. Summarized this system's actual application as well as its economic value.
