Application And Analysis Based On The Construction Of XX Digital City

In recent years, the digital city constructions in many places arealready in full swing. The achievements of digital city construction havebeen used widely in many fields and departments such as land, electricity,agriculture. The Handan city was the first to complete the nationaldigital city construction of city, in Hebei province to realize the "fourfirst". The construction of Handan digital geo-spatial framework is theneed of buildding a conservation-minded society and improving the levelof information management system of Handan city government. Theconstruction of Handan digital city can not only to solve the basic urbanmanagement issues, such as the non-uniform data format and informationgap in the basic geographic information and also make the urban managementand geographic information services convenient, real,3D visualization,The urban management upgrade to a new stage based on informationtechnology tools. The construction of Digital Handan lays a solidfoundation for the Handan City "integration" of e-government, providingauthoritative and convenient public geographic information services forthe public.This study takes the construction of Handan digital city as an example.summarizes the technical routes and some problems encountered during theconstruction of digital Handan and demonstration of digital Handanconstruction process, And combined with the construction of smart Handanto analyze trends the future applications of digital Handan, the mainresearch results are as follows:1）This paper studied the key technologies of the current digital city construction and the future digital city application development,including synchronous display, query, analysis of two dimensional vectorand the three-dimensional model Vast geographic information data engineconcurrent access technology; Confidential data processing technology;Big data technology, cloud computing technology, sensor technology,mobile Internet technology, etc.2）This paper takes the construction and pratical application of thedigital Handan geo-spatial framework as an example, concludes a set oftechnical route including data acquisition, data warehousing, platformconstruction, data updating, platform service/function application andaudit. At the same time, this research summarizes some issues of theconstruction and application of digital Handan, providing a model andreference for other cities.3）The research and analysis of digital Handan future applicationdevelopment direction, the results show that the digital Handan will beapplied mostly in city emergency command, the integration of urban groundand underground space, urban indoor navigation, online environmentmonitoring, digital city360degree streect view. It will bringconvenience to the public life and improve the comprehensive managementlevel of Handan city government departments and the city emergency commandability.4）With the widespread development and application of "ubiquitous"cloud computing, big data, mobile Internet and the new generation ofinformation technology, It will link the reality Handan and the digitalHandan to achieve the smart Handan, so the future digital Handanapplication development direction also will be more intelligent, andconvenient, it will play an import role in wisdom travelling, wisdomcatering, wisdom intelligent, pipe network and so on.
