关于《中国土地资源调查数据集》的专题地图制作技术

以《中国土地资源调查数据集》中的专题地图制作技术为例 ,提出了基于现有 GIS与桌面出版系统功能的集成式的现代专题地图制作系统的软硬件构成和制作工艺流程 ,简要分析了该系统中有关数据接口、分析和处理等方面的特点 ,认为发展现有的 GIS系统 ,提高它的兼容性及制图出版能力 ,同时桌面出版系统借鉴 GIS技术 ,提供数据库操作功能 ,能够直接不丢失信息地读取 GIS数据将是未来的发展方向。

Technology of Thematic Mapping in the Atlas of "China Land Resources Investigation Dataset"

"China Land Resources Investigation Dataset", one of the national land investigation products, shows the present status of land use and property situation in China. It is the composition of tables, thematic maps, text explanation and pictures. The statistical cell spreads out from the whole world, the 30 representative countries, and the provinces/counties of China. About 40% of the dataset is more than 50 pieces and 309×460mm format thematic maps.Since it has to be finished and published in 3 months; so the modern technical of cartography adopted. 　　Fully digital cartography system has characteristics in mapping with high speed, high accuracy, quick update and WYSWYG. It has solved the problem of long production periods and slow update in traditional mapping. 　　Firstly, present situation of the modern cartography and publishing system based GIS are analyzed simply. Two representative systems such as the MGE system of the American Intergraph Company and the Mirage V4.5 system of the Founder Group are analyzed and compared. 　　Secondly, taking the cartography technology used in the atlas as an example, the supported hardware and software structure of the modern cartography system based on the integration of GIS and desktop publish system are brought forward. Especially the various software system functions such as GIS, DTP and office system are focused. 　　Thirdly,the technical flow of digital mapping is presented. The main tasks and goals of various stages from start to end are discussed. 　　Lastly,some system analysis and technical issues including the data interfaces, data analysis and data processing are discussed.
