The invention relates to the technical field of geographic information systems, in particular to a construction method, a system and a drawing method of an ArcGIS-based online intelligent drawing system.
Background
The smart city promotes a new concept and a new mode of city planning, construction, management and service intellectualization by applying new generation information technologies such as internet of things, cloud computing, big data and geographic information integration, and from the concept of the smart city, a Geographic Information System (GIS) and related technologies thereof form a core technology of smart city construction in parallel together with novel IT technologies such as cloud computing, internet of things and big data; according to '2016 + 2018 task division of a novel intelligent city construction department coordination workgroup' issued by the national development reform committee and the central network letter office, in division of labor of construction of an intelligent city, the positioning and the function of a mapping and geographic information department are responsible for constructing urban space-time infrastructure which is used as an important component of the intelligent city, is not only an indispensable and basic information resource of the intelligent city, but also a carrier for other information exchange sharing and cooperative application, and the core technology for constructing the urban space-time infrastructure needs to utilize a Geographic Information System (GIS) and related technologies; a Geographic Information System (GIS) collects or imports data, and after a series of editing, processing and analyzing, the final purpose is visualization, namely drawing and outputting; therefore, it can be said that map making is one of the main purposes of Geographic Information System (GIS) related technology application, and the GIS is one of the core technologies of smart city construction, so that, based on GIS and related technologies, development of an online and intelligent map making system is an important work content in smart city construction.
Desktop tools in common Geographic Information System (GIS) software, such as ArcGIS Desktop, Supermap iDesktop, etc., generally include advanced geographic analysis and processing capabilities, provide powerful editing tools, and complete map production processes, but traditional Desktop software is mainly for relatively professional users, the provided drawing function is professional and complex, the desktop software mostly adopts a single machine and a deployment mode of a C/S framework, the application range of a user is limited, the smart city space-time infrastructure needs to provide mapping service for every department and every industry of the city, the user range is wide, moreover, most users are not familiar with professional desktop software, and in addition, rapid, efficient, online and intelligent map drawing is performed by using data services and functional services provided by smart city space-time infrastructures, so that the core appeal of many smart city application department users is achieved.
At present, Desktop tools in the Geographic Information System (GIS) software, such as ArcGIS Desktop, Supermap itdesktop, etc., are mostly adopted in the existing map making, and the following disadvantages generally exist: 1) the method is professional and complex, and is not suitable for popularization and use in all departments of the smart city: although the professional desktop tools include advanced geographic analysis and data processing capabilities and provide powerful editing tools and a complete map production process, users in many departments of smart cities are often not familiar with the use of professional software and are more difficult to perform conventional map drawing operations by using the professional desktop tools; 2) the deployment mode of single machine and C/S architecture is not beneficial to multi-user online and collaborative drawing: the professional desktop tools mostly adopt a single machine and C/S (client/Server) architecture deployment mode, the user application range is limited mainly aiming at individual users of map making, the smart city space-time infrastructure needs to provide map making services for all departments and all industries of a city, the user range is wide, and the single machine deployment mode is obviously not beneficial to multi-user online collaborative map making; 3) map drawing results are difficult to satisfy sharing and communication of multiple users: because professional desktop tools are professional and complex and are mostly deployed in a mode of single machine and C/S architecture, the map drawing result is difficult to share and exchange among multiple users; 4) the cloud computing architecture is difficult to fully utilize for big data analysis and drawing: with the application of big data, especially space-time big data, in smart cities becoming more and more extensive, users often need to map on the basis of analyzing the space-time big data, and the traditional desktop mapping tool does not support a cloud computing architecture, so that the space-time big data is difficult to be analyzed quickly and efficiently on line by fully utilizing computing resources of a cloud computing center.
