文回顾与评述了三维GIS的相关发展情况,探讨了三维GIS的有关基本问题,如数据获取、大数据量存贮与处理、三维空间分析,同时指出科学计算可视化、数据库系统管理、数字影象处理等技术的成熟和二维GIS长期发展提供的理论实践经验等为三维GIS的发展提供了良好的基础。最后为三维GIS实际系统的开发提出了几个值得注意的要点。-In this paper,the review and comment on the development of 3 dimension GIS are first made.Then the basic aspects about 3D GIS,such as data acquisition,storing and processing of mass data,analysis of 3D space,are discussed.Meanwhile, it points out that the techniques such as scientific computation visualization,database system management and digital image processing,and theories and experiences provided by development of 2D GIS offer a better platform form the development of 3D GIS.Finaally,some key points in developing practical system of 3D GIS is proposed.

tframeviewer,thtmlviewer,和tframebrowser
TFrameViewer, ThtmlViewer, and TFrameBrowser
The HTML component set consists of the ThtmlViewer, TFrameViewer, and TFrameBrowser components. All three are HTML document display components:
ThtmlViewer The basic component. ThtmlViewer displays single (non-frame) documents. It also forms the basis for the other two components.
TFrameViewer Displays both Frame and single HTML documents. TFrameViewer is oriented more for local disk file use.
TFrameBrowser Also displays Frame and single HTML documents. However, TFrameBrower is oriented toward Internet style protocols and URL usage. Additional code and/or components are generally required to use TFrameBrowser.
If you know that your appication will not be using Frames, you can save a fair amount of code overhead by using ThtmlViewer rather than one of the Frame components. Many operations are also simpler using ThtmlViewer. -TFrameViewer, ThtmlViewer, and TFrameBrowser
The HTML component set consists of the ThtmlVie

FCM算法是一种基于划分的聚类算法,它的思想就是使得被划分到同一簇的对象之间相似度最大,而不同簇之间的相似度最小。模糊C均值算法是普通C均值算法的改进,普通C均值算法对于数据的划分是硬性的,而FCM则是一种柔性的模糊划分。在介绍FCM具体算法之前我们先介绍一些模糊集合的基本知识。-FCM algorithm is a clustering algorithm based on the division of its thinking is that it is making is divided into clusters with the greatest similarity between the object, and different similarity between the smallest cluster. Fuzzy C-means algorithm is an ordinary C-means algorithm, the general C-means algorithm for data delineation is rigid, while the FCM is a soft fuzzy partition. FCM in the introduction prior to the specific algorithm we first introduce some basic knowledge of fuzzy sets.
