Research On Geographic Information Data Processing Method For Digital City Construction

The current rapid social and economic development, at the same time, thedeepening degree of information, China’s urban construction gradually towards thefurther development, planning and construction, urban planning and construction,basic industrial planning and regional economic development plans and otherinfrastructure to demand digital city construction is very urgent, in order to betterrespond to the development of society, to raise public life experience, digital cityconstruction becomes particularly important. In the process of digitizing the entirecity construction, geographical information and data played a very important role,depending on the user, divided into basic geographic information data, bothgovernment and the public version version of the framework data frame data, whichafter all from the basic geographic information data extracted through the treatmentprocess, but also need to go through these two types of data confidentiality processingof the relevant government departments to share and use. From this, basic geographicinformation data in the process of digitizing the entire city to play a fundamental roleis to provide support for all data, which has multi-source, multi-scale andmulti-resolution side features the entire digital city construction core. Therefore, howto quickly and accurately on the basis of data processing is to promote theconstruction of digital cities important part of the problem we have to face.In this paper, the digital city construction, the geographic information dataacquisition and processing method was studied, established a set of multi-scale,multiple source geographic information data processing process and methods. Mainlystudy the basic geographic information data acquisition method, summarizes DLG,,DOM, DEM,3d data,Name address etc.), e-government framework of geographicdata, the public version of the framework of geographical data processing process andmethods and geographic database construction, and integration of multi-source andmulti-scale geographic information database of the technological process and method,for the digital city construction, and even wisdom city construction in the process ofdata processing and database construction provides the basis for reference.
