Research And Development Of Engineering Survey Data Processing System

The survey data processing plays an important role in geodesy and engineering and is the core of surveying. It is also the basic tool of research and engineering practice. With the development of large domestic projects, there are new requirements in many aspects of survey data processing. The integration and automation of survey data processing is the key requirement in surveying and mapping. So the research and development of the system is not only part of survey engineering but also has practical significance in actual project.The main content of the three parts in the thesis is as follows:(1) descript the development of survey data processing in both of theoretical and technical aspects. Analyzes the strengths and weaknesses of the existing software systems, summarizes the background and significance of the subject in this article. (2)Describes the basic theory of survey data processing, analyzes the key technologies of data processing:approximate coordinate calculation, gross error detection, closed loop searching, data model designing. (3)develops an economic and practical software using.Net platform and C# language whose main functions include data downloading, data format transforming, general adjustment deformation analysis and report output. The software can improve the progress of the project and reduce the workload of survey data processing the main designing and developing works is as follows:(1) Fully analyzes the data concept involved in survey data processing and completes the model design. Use T-sql script to create database.(2) Software architecture use MVVM design model to isolate the persistent and non persistent data with view and models which facilitate system maintenance and improve the scalability of the software.(3) Use WPF technology to deigns user interface and developed easy and intuitive user interface of input and output to reduce the errors in data processing(4) Use Entity Framework solution to access the database with object-oriented way which can reduce the coupling between business problem of data processing and the database...
