【摘要】：面对经济社会的不断发展,我国先后在“十一五”、“十二五”期间就国土资源信息共享服务平台建设进行了详细的规定。目前我国大部分省市都建立了国土资源遥感监测“一张图”地理信息共享平台,为我国国土资源事业的发展提供了很大的帮助。作为我国重点发展的沿海主要港口,日照港区位优势显著,发展迅速,但由于缺乏统一的标准体系和共享管理机制,很多部门和单位为了自身的发展组织人员对自己业务范围内的数据进行采集和处理,由此造成了港区内系统重复建设,共享机制不完善导致信息化程度低、数据冗余等问题。本文针对以上问题,提出了日照港“一张图”地理信息共享平台,以该平台为研究对象,建立了港区基础地理信息数据分类和编码的标准,为港区基础信息测绘、数据处理和入库提供依据;提出了地图数据格式转化方法和专题图制作方法,基于该方法对种类繁多的基础地理信息数据进行了处理,按照《1:500地形图图式》制作了港区地理要素符号,参照国内外成熟的地图制作实例,进行了港区地图的配色,并对制作完成的地图进行了制图综合处理;针对制作完成的专题地图,按照数据库属性数据入库要求进行了图层属性结构表的设计,为空间数据库建设提供支持;为避免平台之间不能进行数据共享,编写了本平台嵌入其他应用系统接口,从而避免了资源浪费;开发完成了基于B/S模式的港区地理信息共享平台和基于C/S模式的数据库管理系统,从而实现了数据处理、展示、查询、管理一体化集成,为港区地理信息共享服务。建立港口资源信息共享“一张图”,使得不同单位的人员可以使用同一套数据来了解港区中不同地理信息资源的分布状况,同时利用数据库技术实现特殊资源的实时动态显示,逐步形成空间数据的信息化,为真正实现资源共享、信息产业化做出贡献。
[Abstract]:In the face of the continuous development of economy and society, the construction of land and resources information sharing service platform has been stipulated in detail in the period of the 11th Five-Year Plan and the 12th Five-Year Plan in China. At present, most provinces and cities in China have established the "one map" geographic information sharing platform for remote sensing monitoring of land and resources, which provides a great help for the development of land and resources in our country. As the main coastal port of our country, Rizhao Port has obvious location advantage and rapid development. However, it lacks a unified standard system and shared management mechanism. For the sake of their own development, many departments and units organize personnel to collect and process the data in their own business scope, which results in the repeated construction of the system in the port area, the imperfection of the sharing mechanism leads to the low level of informatization and the redundancy of the data, and so on. Aiming at the above problems, this paper puts forward the "one map" geographic information sharing platform of Rizhao Port. Taking the platform as the research object, the standard of classification and coding of the basic geographic information data of the port area is established, which can be used as the surveying and mapping of the basic information of the port area. Data processing and storage to provide the basis; The transformation method of map data format and the method of making thematic map are put forward. Based on this method, various kinds of basic geographic information data are processed, and the geographical element symbols of port area are made according to < 1: 500 topographic map schema >. With reference to the mature map making examples at home and abroad, the color matching of the map of the port area is carried out, and the cartographic generalization of the completed map is carried out. According to the requirement of database attribute data, the design of layer attribute structure table is carried out according to the completed thematic map, which provides support for the construction of spatial database. In order to avoid the data sharing between platforms, the platform is embedded in other application system interfaces, thus avoiding the waste of resources. The GIS sharing platform based on B / S mode and the database management system based on C / S mode are developed, which can realize the integration of data processing, display, query and management, and serve the sharing of geographical information in Hong Kong. The establishment of "one map" for information sharing of port resources enables people of different units to use the same set of data to understand the distribution of different geographical information resources in port areas, and to realize the real-time and dynamic display of special resources by using database technology. Gradually form the information of spatial data, for the real realization of resource sharing, information industrialization.
