【摘要】：目前城市地理信息，如与建筑物相关的数据大部分是以二维的形式存储。地理信息系统的软件也是在二维数据上进行操作，诸如查询，修改和更新等。二维数据表示地理信息限制了2DGIS的发展，对一些需要三维表示的数据，2DGIS不能很好地满足要求。用3DGIS表示现实世界除了可以帮助查询者清晰，直观的获得所关心的信息，还可以动态的，交互的分析二维平面和垂直方向位置信息之间的关系。尽管3DGIS的应用有很大的优势，但是由于视野的局限性，用户在浏览查询得到的三维信息时，，就容易产生错觉，不能很好的分析三维信息，因此需要实现2DGIS和3DGIS的一体化，即实现2DGIS与3DGIS的结合，查询三维信息需要在3DGIS中实现，而查询和分析二维信息则需要在2DGIS中实现。本论文开发了基于GIS的油田社区信息系统，实现了主要的功能，主要包括2DGIS的基本功能，3DGIS的三维空间信息查询、漫游、分析功能，以及2DGIS和3DGIS互响应功能。设计开发了一个基于GIS的油田社区信息系统的原型系统－SLInfoSys（ShenLi YouTian Infor System）。本文的主要工作概括如下：（1）2DGIS系统的建立实现了2DGIS的基本功能，包括支持多种数据文件；图形显示；查询分析；空间分析；2DGIS到3DGIS的互响应等。（2）研究了三维模型的建立过程三维模型的建立包括模型数据的获取，模型数据的数据结构的选取等。3DGIS采用基于结构实体几何法和边界表示法的箱式分割数据结构，并以此为基础实现相应的数据模型的设计。（3）三维模型可视化的设计通过VRML中间数据格式，对数据进行进行分析，处理，然后将空间数据和属性数据存储到数据库中。在图形显示或查询分析时，直接从数据库中读取相应的空间数据，重构三维虚拟场景，实现三维数据的可视化。（4）交互操作的实现系统提供了三种基本的交互操作：用户与2DGIS的交互；用户与3DGIS的交互；2DGIS和3DGIS的交互。对互响应原理做了一定程度的研究。
[Abstract]:At present, most of the urban geographical information, such as building-related data, is stored in two-dimensional form. Geographic Information system (GIS) software also operates on two-dimensional data, such as query, modification and update. Two-dimensional data representation of geographic information limits the development of 2DGIS. 2DGIS can not meet the requirements of some data that need three-dimensional representation. Using 3DGIS to represent the real world can not only help the querier to obtain the concerned information clearly and intuitively, but also analyze the relationship between the two-dimensional plane and the vertical position information dynamically and interactively. Although the application of 3DGIS has great advantages, because of the limitation of visual field, users are prone to illusion when browsing the three-dimensional information obtained by query, and can not analyze the three-dimensional information very well, so it is necessary to realize the integration of 2DGIS and 3DGIS. That is, to realize the combination of 2DGIS and 3DGIS, querying 3D information needs to be implemented in 3DGIS, while querying and analyzing 2D information needs to be implemented in 2DGIS. In this paper, an oil field community information system based on GIS is developed, which realizes the main functions, including the basic functions of 2DGIS, the three-dimensional spatial information query, roaming and analysis functions of 3DGIS, and the mutual response function of 2DGIS and 3DGIS. A prototype system of oil field community information system based on GIS, SLInfoSys (ShenLi YouTian Infor System)., is designed and developed. The main work of this paper is summarized as follows: (1) the establishment of 2DGIS system realizes the basic functions of 2DGIS, including supporting a variety of data files, graphic display, query analysis, spatial analysis, 2DGIS to 3DGIS mutual response and so on. (2) the establishment of 3D model includes the acquisition of model data and the selection of data structure of model data. 3DGIS adopts box segmentation data structure based on structural entity geometry method and boundary representation method. On this basis, the design of the corresponding data model is realized. (3) the design of 3D model visualization analyzes and processes the data through VRML intermediate data format, and then stores the spatial data and attribute data into the database. In the process of graphic display or query analysis, the corresponding spatial data are read directly from the database, the 3D virtual scene is reconstructed, and the visualization of 3D data is realized. (4) the implementation system of interactive operation provides three basic interactive operations: the interaction between user and 2DGIS, the interaction between user and 3DGIS, and the interaction between 2DGIS and 3DGIS. The principle of mutual response is studied to a certain extent.
