Digital Yangling Platform' Production Based On The ArcGIS

Digital City is the use of communication networks and digital information technology,geographic information system (GIS), remote sensing (RS), global positioning system (GPS)and a virtual simulation technology and other technology system, build a city informationplatform. Information platform in the city, you can query a variety of resource information tothe city, and their integration, management and analysis.The city as a center of regional political, economic cultural and information, which is theradiation source and a gathering place of the human civilization. Looking to the future of thecity, which can cater to the global wave of information technology, will be developed rapidly.Digital City, also known as network cities, smart cities, information cities, which Integrateduse infrastructure and the functional mechanism of GIS, remote sensing, telemetry, networkcommunications, database, multimedia and virtual reality and other advanced informationtechnology to make a full range of digital acquisition and processing.Used the powerfulsupport features to urban geography, resources, ecological environment, population,economic, social and so complex system. And also used the rehearsal of effect of majordecisions and planning projections for future development.This article access to the extensive literature, is to do a certain amount analysisdescription on the connotation of the digital City, the background of digital city' production,the research status of the domestic and international digital city, the construction content ofdigital city, the basic theory of the construction of digital cities, geographic informationsystems with "Digital City" and China's digital city construction problems and developmentcountermeasures.Based on Yangling district, using the remote sensing images, the administrative maps,topographic maps, land use maps and a variety of statistical data as the basic data source,making digital operation on the geographic information of the study area using ArcGIS9.3software, reconstructing vector graphic data and attribute data based on the raw data,realizing the composite processing and application of text data,statistics data,graphics dataand remote sensing data of a variety of data.Using the bottom picture of Yangling high-resolution remote sensing image as the reference map, and based on administrative map, topography map, land use status map as thereference data, made digital processing on Yangling rural homestead, on the Yangling villagesand towns, on Yangling administrative divisions;and under the reference of Yangling collectedsoil data of distribution types, made the Yangling soil classification maps; and made asmall-scale digitization of Yangling demonstration area under the reference of Google EarthYangling satellite map, to show regional location and so on.
