【摘要】：國家空間信息基礎(chǔ)設(shè)施建設(shè)是國民經(jīng)濟(jì)和社會信息化水平整體實力的重要體現(xiàn)，也是目前測繪行業(yè)的主要任務(wù)。國家空間信息基礎(chǔ)設(shè)施的核心是建立國家基礎(chǔ)地理信息數(shù)據(jù)庫，以4D產(chǎn)品為代表，這些數(shù)據(jù)需要大量的人力與物力來維護(hù)。空間數(shù)據(jù)和地圖作為基礎(chǔ)地理信息中比較重要的兩種數(shù)據(jù)，是對同一空間要素的兩種不同抽象表達(dá)，本質(zhì)上是一致的。多年來，空間數(shù)據(jù)與地圖的一體化研究一直是地理信息領(lǐng)域的熱點(diǎn)問題，行業(yè)內(nèi)對其也有了高度重視，人們在這兩種數(shù)據(jù)的一體化生產(chǎn)流程、一體化數(shù)據(jù)模型、一體化應(yīng)用等多方面做了很多研究�，F(xiàn)有的空間數(shù)據(jù)和地圖經(jīng)常是對同一目標(biāo)區(qū)域重復(fù)生產(chǎn)，造成人力和物力的耗費(fèi)，數(shù)據(jù)冗余大。陜西測繪局與長安大學(xué)共同提出的數(shù)字線劃地圖產(chǎn)品，是一種與軟件無關(guān)的一體化數(shù)據(jù)，能同時生產(chǎn)這兩種數(shù)據(jù)，且保持兩種數(shù)據(jù)的相互關(guān)聯(lián)及一致性，對國家空間基礎(chǔ)設(shè)施的發(fā)展具有重要意義，本文對其生產(chǎn)工藝和生產(chǎn)流程進(jìn)行研究。 數(shù)字線劃地圖以拓?fù)涞貓D模型為理論基礎(chǔ)，是表達(dá)地形圖要素的矢量數(shù)據(jù)集，同時保存要素間的空間關(guān)系、要素相關(guān)的屬性信息、要素的地圖表達(dá)數(shù)據(jù)。該產(chǎn)品中要素集合的幾何、屬性部分就是空間數(shù)據(jù)，而符號圖形部分的集合就是地圖。兩種數(shù)據(jù)在一種數(shù)據(jù)模型下合理的表達(dá)，優(yōu)化生產(chǎn)工序，減少中間環(huán)節(jié)，兩者互為參照。它以地圖表達(dá)機(jī)制實現(xiàn)空間數(shù)據(jù)的可視化，空間數(shù)據(jù)和地圖符號具有一定的關(guān)聯(lián)性，也具有獨(dú)立性，符號的編輯不會影響空間數(shù)據(jù)的精度。針對數(shù)字線劃地圖的特點(diǎn)，論文中探討了該產(chǎn)品的生產(chǎn)工藝，包括模板的制作、幾何構(gòu)造工藝、實體構(gòu)造工藝和地圖構(gòu)造工藝，并對該構(gòu)造工藝與傳統(tǒng)的繪制工藝進(jìn)行效率和質(zhì)量方面的比較。同時，在數(shù)字線劃地圖的生產(chǎn)平臺上，通過1:10000數(shù)據(jù)加工，驗證了數(shù)字線劃地圖的生產(chǎn)工藝。 本文主要針對數(shù)字線劃地圖的生產(chǎn)，從數(shù)據(jù)模型、生產(chǎn)流程、生產(chǎn)工藝到應(yīng)用實踐上都做了一系列工作，驗證了構(gòu)造工藝和繪制工藝兩種生產(chǎn)工藝下的生產(chǎn)效率和質(zhì)量，說明數(shù)字線劃地圖產(chǎn)品生產(chǎn)工藝的高效性與實用性價值。
[Abstract]:The construction of national spatial information infrastructure is an important embodiment of the overall strength of the national economy and the level of social information, and is also the main task of the surveying and mapping industry at present. The core of the national spatial information infrastructure is the establishment of the national basic geographic information database, represented by 4D products, which requires a great deal of manpower and material resources to maintain. Spatial data and map are two kinds of important data in the basic geographic information. They are two different abstract expressions of the same spatial elements, which are consistent in nature. Over the years, the integration of spatial data and maps has been a hot issue in the field of geographic information, and has been attached great importance to in the industry, people in these two kinds of data integrated production process, integrated data model, A lot of research has been done on integrative application. The existing spatial data and maps are often repeated production to the same target area, resulting in the cost of manpower and material resources, and the data redundancy. The digital line map product proposed by Shaanxi Survey and Mapping Bureau and Changan University is a kind of integrated data independent of software. It can produce the two kinds of data at the same time and maintain the correlation and consistency of the two kinds of data. It is of great significance to the development of national space infrastructure. Digital line map is based on topological map model. It is a vector data set to express the elements of topographic map. At the same time, it preserves the spatial relationship between the elements, the attribute information related to the elements, and the map representation data of the elements. The geometric and attribute parts of the set of elements in the product are spatial data, while the set of symbolic graphics is the map. The two kinds of data are expressed reasonably under one data model, the production procedure is optimized and the intermediate link is reduced. The two kinds of data are referred to each other. It realizes the visualization of spatial data by the mechanism of map representation. The spatial data and the map symbol are related and independent, and the editing of the symbols will not affect the precision of the spatial data. According to the characteristics of digital line map, this paper discusses the production technology of this product, including the manufacture of template, geometric construction, solid construction and map construction. The efficiency and quality of the construction process are compared with the traditional drawing process. At the same time, on the production platform of digital line map, the production technology of digital line map is verified by 1: 10000 data processing. This paper mainly aims at the production of digital line map, from data model, production process, production process to application practice, has done a series of work, has verified the production efficiency and the quality under two kinds of production technology: construction technology and drawing technology. This paper explains the high efficiency and practical value of the production technology of digital line map.
