Digital Mapping And Database Building Based On Multi-source Data

In recent years,surveying and mapping technology has increasingly served the direction of government decision-making,urban construction,urban planning,etc.The new service content has put forward new requirements and challenges for surveying and mapping technology.Traditional surveying and mapping is more to provide a single surveying and mapping results to serve specific needs,while the government,planning and other departments need more integration and analysis of multi-source surveying and mapping data for decision-making and planning.Therefore,how to efficiently use existing sources of data combined with demand data for rapid mapping and database building,and go hand in hand Line analysis and display is an important demand of the government and related departments at present.Aiming at the above problems,this paper studies the acquisition,processing,fusion,database building,analysis and display of multi-source data of attachments on the ground,establishes a fast way of automatic mapping of field data acquisition and mapping software,and forms a new technological process.Through the combination and expansion of multi-source data,it is easy to check.Multi-Source Data Integrated Management Platform for Inquiry and Analysis and Display.The main research contents include: acquisition and fusion of multi-source aboveground attachment data: the methods of acquisition,processing and fusion of multi-source aboveground attachment data are studied,and a new process of multi-source mapping data acquisition is formed;digital mapping of multi-source aboveground attachment data: three mapping methods are applied to study the integration of data.The methods of on-site surveying and updating,multi-source ground attachment data database building,geographic information data structure suitable for the development characteristics of urban fringe areas and core methods of multi-source data integrated management platform are explored.Through the above research,a multi-source data integrated management platform has been formed.The platform has the characteristics of flexible display of results,convenient query,accurate data and convenient updating.It realizes the comprehensive query,analysis and display of multi-source data.The construction of Beijing New Business District is based on the spirit of General Secretary Xi Jinping’s two visits to Beijing’s important speeches.It is necessary to firmly establish and thoroughly implement new development concepts,closely focus on the positioning of "four centers","four services" and the criteria of "the best areas",which conform to the general outline of current mediation work.This paper takes the construction project as an example to quickly map and manage the data of the survey of attachments in the Inland area.Through the method test,this method saves the cost of production of attachments survey personnel and equipment on the ground,and greatly shortens the survey and mapping cycle.It can create more benefits for surveying and mapping units and provide more abundant data support for other departments.
