Ephemeris data by comparison is very precise orbital and clock correction for each SV and is necessary for precise positioning.

Ephemeris 数据相比之下是十分精确的轨道和时钟纠正信息，每一颗卫星只会广播自己的Ephemeris 数据，这类数据的有效期或许有几个小时（取决于广播信息的包含的内容）。

This method uses all noisy datapoints directly to implement triangulation and dispenses with smoothing and datareduction process, which may lead to loss of geometric character. Moreover, thismethod is of lower complexity than other triangulation and the amount of vertexes inmesh can also be calculated, so we can control the size of mesh in advance. At last, apractical example is given to prove its effectiveness.

这种方法利用全部数据点信息进行网格剖分，无需对数据进行平滑、精简等预处理，避免了因平滑或精简而丢失重要的几何信息的可能，这种方法不仅比现有三角网格剖分算法降低了算法复杂度，而且具有可以直接处理带有噪声的数据，网格规模可控，生成的三角网格形状较好等优点。

Using the model of whole data object-oriented, the paper abstracts several objects of campus pictures, buildings, floor pictures and rooms, through the department office attributes of the room, links space information with non-space information, realizes the interconnections of GIS, OA, MIS, interflows, and inter-dynamic, really accomplishes "model of digital campus" of the space data and attribute data seamless link.

使用面向对象的整体数据模型，抽象出校园图、楼、楼层图和房间几个对象，通过房间具有部门办公室的属性，将空间信息与非空间信息联系起来，实现GIS、OA、MIS的互连、互通、互动，建立了空间数据和属性数据无缝连接的&数字校园模型&。

The new one has the following advantages:(1) inheriting and enlarging attribute data management function of original SOTER, and enhancing the integrith and safety of SOTER;(2) integrating the attribute database, spatial database and model base into a unique system, and using the windows graphic user interface, as interactive tools which make establishment and maintenance of SOTER database convenient;(3) promoting the quantitativity, model standardization and automation of soil information, and serring as a good example for building new soil databases and information system.

新系统继承和扩充了原有系统的属性数据管理功能，增强了SOTER数据库的完整性与安全性；将属性数据管理、空间数据管理和模型库集成在一个系统中，采用Windows的图形用户界面与用户交互，使SOTER数据库的建立与维扩更加方便；同时促进了土壤信息应用的定量化、模式化和自动化，也为进一步建立土壤信息系统打下了良好基础。

In this paper a novel ontology-based data semantic fusing frame named ODSF is introduced, the basic element of ODSF is dataset its semantic is obtained by the mapping between the domain ontology and dataset. ODSF adopts nested relation model to represent the schema information of dataset, and realizes the data fusing from coarse-grained level to the small-grained level by wrapping the datasets registered in virtual database as a new dataset. We also present the semantic model of ODSF, query executing process and algorithm of virtual database, so ODSF can provide the semantic supported and QoS supported data access for user. The experiments demonstrate our work and show the feasibility and effectiveness of ODSF and its key techniques.

本文提出了基于本体的语义数据容融合方法ODSF；该方法中的基本元素是数据对象，通过数据对象和领域本体之间的映射关系来表达数据对象的语义，使用嵌套关系模型来表达数据对象的模式信息，通过一个网格节点中集成的所有数据对象作为下一个节点的数据对象来实现数据资源由粗到细的融合；定义了ODSF的语义模型，给出了虚拟数据库的查询执行过程和算法，可以为使用者提供具有语义支持、服务质量保障的数据访问服务；通过原型系统验证了ODSF中理论和关键技术的正确性和可行性。

The Geographic Information System theory as a guide, point-set topology theory as basis, this paper uses object-oriented method to study on profile-based three-dimensional topological data model and data structure. By use of computational geometry, GIS, computer graphics images, 3DGM, the construction and dynamic updating methods of 3DGM are researched on the basis of amended OO-Solid data model.

本文以地理信息系统理论为指导，以点集拓扑理论为基础，采用面向对象的方法研究了基于剖面的三维拓扑数据模型和数据结构，采用计算几何、地理信息系统、计算机图形图像学等方法研究了基于修正后的OO-Solid数据模型的三维地质模型构建与动态更新方法。

However, it can only implement the limited operation to the spatial objects, cannot carry on transformation, index, interlink age and excavation to the spatial data, and hard integrate other information with combining map variable to set up and analysis new variable. Meanwhile, relational model in the traditional DBMS and the object- oriented modeling do not completely suit the spatial application domain. The relational model can handle topological relation well, but shows inabilities to that complicated level crossing the spatial region. Object-oriented model using software method based on the principle of the customer defined data type supports the abstract data type, especially spatial abstract data type, and possesses polymorphism and inheritances, and it can deal with topological and the layer relation, but hardly processes important continuous phenomenon in space.

GIS是当今操作有关空间信息的成熟工具和技术，但其只能对空间对象进行有限的操作，不能对空间数据进行变换、索引、链接和挖掘，难以集成其他信息来构建和分析新变量；而传统数据库管理模型中的关系模型和面向对象建模也不完全适合空间应用这一领域，关系模型能够较好地处理拓扑关系，但对表示横跨空间区域的复杂层次却无能为力；面向对象模型的软件方法支持抽象数据类型，特别是空间抽象数据类型，具有继承性和多态性，能够处理拓扑和层次关系，但难以处理空间中重要的连续性现象。

In addition, more detail analysis and design on the prototyped system are done. The PPOR (Product, Process, Organization and Resource) model is proposed as the core and inner framework of PDM supporting collaborative work.

本文提出了产品数据管理的PPOR模型，该模型是产品数据管理内部框架和核心，亦是支持协同工作的信息框架，各信息模型之间相互关联，并首次以面向对象的EXPRESS语言给予完全计算机可实现的描述，从而构造了一个比较完整的产品数据管理内核。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
