【摘要】：信息化时代已经以迅猛的脚步跨入当今世界。经济社会的各个领域在信息技术的带领下正发生着深刻的变革。同样国土资源管理也面临着势不可挡、发展迅猛的信息化革命。近年来，“数字国土”工程的实施、国家“一张图”工作的积极推进，各省、市、县国土资源信息化建设工作正如火如荼的开展。然而“一张图”的数据来源广泛、数据种类繁多、格式多源、数据量大等问题，，势必对数据管理、数据地图服务及应用等带来一定的困难。本论文结合江西省“一张图”工程建设项目，首先研究了基于MapGIS的江西省省级“一张图”工程的平台技术背景，结合江西省“一张图”工程建设的技术路线，分析研究了江西省“一张图”工程的总体系统框架、C/S和B/S混搭的网络运行结构。其次对空间数据库的结构内容、数据的组织存储和核心数据库的设计等进行了详细的研究分析。最后论述了“一张图”工程建设中的功能模块以及实现这些功能的关键技术，研究的主要内容和成果包括： ⒈入库前的数据需进行一系列规范性的检查，剖析了数据检查流程、导入导出的技术； ⒉省级“一张图”是个浩大的工程，汇集各个县市数据包括矢量数据、影像数据、业务数据等多源异构数据，提出以中间件技术解决异构数据管理的思想及其配置中间件的方法。 ⒊研究分析了WebGIS信息发布、地图瓦片技术在“一张图”工程建设中的应用，以江西省四个年度的遥感影像数据为例，介绍了同一窗口多时域对比浏览技术在“一张图”工程中的实现；根据江西省“一张图”工程的建设情况，阐述了实施地图瓦片技术的系统配置，以江西省会昌县总体规划数据为例，以理论辅以技术实践，详细介绍了地图瓦片技术的发布实现过程； ⒋结合江西省“一张图”三维发布系统的建设，介绍了二三维一体化的雏形。
[Abstract]:The information age has entered the world with swift and violent steps. Under the leadership of information technology, profound changes are taking place in all fields of economy and society. Similarly, land and resources management is also facing an unstoppable, rapid development of the information revolution. In recent years, with the implementation of the "Digital Land" project and the active promotion of the "one map" work, the information construction of the land and resources of the provinces, cities and counties is being carried out in full swing. However, the "one chart" has a wide range of data sources, a wide variety of data types, multiple formats, large amounts of data, and so on, which is bound to manage the data. Data map service and application bring some difficulties. In this paper, based on the construction project of "one map" in Jiangxi Province, the platform technology background of "one map" project in Jiangxi province based on MapGIS is studied. Combined with the technical route of the "one drawing" project in Jiangxi Province, the network operation structure of the "one map" project in Jiangxi Province is analyzed and studied, which is composed of C / S and B / S. Secondly, the structure content of spatial database, the organization and storage of data and the design of core database are studied and analyzed in detail. Finally, the function modules in the construction of "one drawing" project and the key technologies to realize these functions are discussed. The main contents and results of the research include: 1 the data before entering the warehouse need a series of normative checks, and the data checking flow is analyzed. The technology of importing and exporting. 2 the provincial "one map" is a huge project, which gathers the data of various counties and cities, including vector data, image data, business data, and so on. This paper puts forward the idea of using middleware technology to solve the problem of heterogeneous data management and the method of configuring middleware. 3 the application of WebGIS information publishing and map tile technology in the construction of "one map" project is studied and analyzed. Taking the remote sensing image data of four years in Jiangxi Province as an example, this paper introduces the realization of the same window multi-time domain contrast browsing technology in the "one picture" project, and according to the construction situation of the "one map" project in Jiangxi Province, The system configuration of implementing map tile technology is expounded. Taking the data of general planning of Huichang County in Jiangxi Province as an example, the theory is used to assist the technical practice. The realization process of map tile technology is introduced in detail, and the embryonic form of integration of two and three dimensions is introduced combining with the construction of "one map" 3D publishing system in Jiangxi Province.
