Research On Digitai Station Location

With the development of social and economic,a variety of factors that affect the digital stations are more complicated than ever,become increasingly important to scientifically determine the spatial location of the site object,and become increasingly difficult.The face of new requirements, station location grid method and the Voronoi diagram exposed many inadequacies, and the development of GIS space site provides new techniques, GIS technology is appliedspatial location field showed a huge advantage.Theoretical knowledge on the basis of the site are involved in the site selection study for the status quo in the current domestic and international space station space was first proposed wavefront advancing to the digital station site, and summarized to promote the use of wavefrontconstitute the Delaunay triangulation algorithm process.This paper analyzes the data base and influencing factors in the site planning of digital terrestrial television broadcasting stations, station propulsion method based on wavefront optimization site analysis method.Digital station location factors complicated the problem, not only related to radio wave propagation characteristics, and topography, population, culture and other related GIS development for the station site to provide new technology means:GIS geographic information analysis capabilities will no doubt be the siting of a scientific, standardized. Overlay analysis, buffer analysis, network analysis, and statistical area, distance, and geospatial information analysis, extraction and location related to geospatial information, and quantitative analysis of the various elements and their spatial relationships.In this paper, based on the spatial distribution of geographic information systems and geographical factors, space analysis, the method for large-scale digital television stations will be planning to provide a new way of thinking.
