Land Survey Delimitation Summary System Development

According to the need of land acquisition, allocation, transfer, agricultural land conversion, land use planning, land development, consolidation and reclamation, the land survey and delimitation is to define the land range, determine the boundary position, draw the land use category, calculate Land area and land classification area, in order to provide scientific, accurate basic data and technical services work of land and resources administrative department in charge of land use approval and cadastral. With the era of information and scientific&technological progress, survey and delimitation transferred from manual operation to automated information processing. There are many shortcomings of China’s current land Surveying delimited data processing software. There is the need to rely on third-party software and you can not deal with spatial data topology. It’s attribute information management capacity is weak and troubleshooting ability is poor. Data collection, report preparation and electronic offer are not high integration of the productions. However, the summary of land survey and delimitation on system development and research is to solve the data collection, reporting, newsletters, plate production, and the integration of information management.The subject of this article is representative of medium-sized hydropower project survey delimitation project. This article Uses software engineering research methods, Managing survey delimited data, combined with popular database and a common programming language as a programming tool, and develop a suitable software system to deal with complex issues.The system design is summarized below:(1) The needs analysis:communication with the user’s user needs, data flow diagrams, data dictionary.(2) Database design:Including design of the database conceptual structure and logical structure. Data flow diagram according to the needs analysis, combined with the storage of data dictionary entries and data entry to generate database ER diagram, according to the logical structure of the ER diagram to establish a database table.(3) Modular design:Mainly based on user needs analysis, data flow diagrams, by the conversion method and the partial adjustment available to the delimitation of the system block diagram of the ground investigation. (4) Interface design:Through the system function and data Analysis and Combined with modular division, Make sure the system consists of the system registry and the main interface and render the system interface to the user.(5) Detailed design:for each event, each module according to a structured program design method using VB6.0design details code.(6) System integration:Established in accordance with the ADO component+of the front of the application+the middle of the back-end Access database applications.Land Surveying summary system has achieved functions of construction project management, Surveying project management, land management, figure spot management, construction unit management, Investigation unit management, classification standards management, government agencies management, summary of the data, data query, report generation, offer database generation Etc.Verified by an example, the use of information technology tools developed land surveying delimitation summary of the system is feasible. Verified by an example, the use of information technology tools developed land surveying delimitation summary of the system is feasible. The ground investigation the delimitation summary system has a high applicability, accuracy, versatility, and efficiency.
