Development And Application Of GIS-based Hydropower Engineering Resettlement Investigation System

The hydropower engineering is basic facilities and public service industries in thenational economy, hydropower immigrants is an important part of hydropower project and it’sa complex systems engineering, policy, involving a wide range of population relocation,infrastructure and even the urban re-planning and construction, to use a lot of documentationand complicated information, and how to effectively manage, query, utilization of the data,concern to the resettlement work efficiency and results. Traditional immigration work is usedof paper maps or CAD drawings, invest more human and inefficient. However, use GISspatial data management and processing power, can improve the efficiency of the resettlementwork, the planning, management and decision-making more scientific. Therefore, strive to dohydropower project resettlement work, there will be conducive to promoting the harmony ofthe national economy, sustainable development, it facilitates implementation ofpeople-oriented, scientific development concept and building a harmonious concept in thereservoir area, and help to improve the building of a harmonious immigrants, so as to ensureand Hydropower Engineering construction quality and safety, to ensure that the lives andproperty of the masses of immigrants, to ensure the smooth progress of the resettlement work,to promote the successful realization of hydropower engineering.In this paper, based on detailed analysis of Hydropower Project Resettlement businessneeds and query a large number of relevant literature. Hydropower immigrants physicalindicators survey system research and development, the use of component technologycombined with the three-tier C/S structure, select ESRI’s the Component Product ArcGISEngine, used object-oriented development language C#integrated Re-development, improvethe efficiency of development and enhance the spatial analysis functions. On the design of thedatabase, ArcSDE spatial data engine and SQL Server2005large database storage resettlement spatial data and attribute data. Through the computer program design to realizethe automation management of migration data, reduce the human factor, to improve thecredibility of the results, data automation, computerized resettlement work. The system has agood user interface, complete the information input, query, statistics and printout by means ofhuman-computer interaction. System is an open system, and lay a good foundation for futuresystem.Overall, through this system design to achieve visualization, digital of immigrationinformation management, greatly improving the efficiency of data management. To provide afull range of information support for hydropower resettlement work, to achieve highefficiency in the true sense of the concept of high-tech immigrants.
