等高线

This paper presents a new algorithm of adding elevation annotation automatically.

提出了一种新的等高线高程自动算法。

At first this paper introduces a new method which is named as the concentric circles cutting method of drawing terrain characteristic line on the basis of contour vector data, and has made the program design and realized to this method.

本文首先介绍了一种基于等高线矢量数据提取地形特征线的新方法——同心圆剖切法，并对该方法进行了程序设计与实现。

The cartographic generalization system can be used to generalize contours and rivers. Although it don't realize completely automation, most tasks can be done by the program, and by means of the interactive method, the results are similar with the results generalized by cartographer.

该系统实现了等高线以及河流的综合，虽然不是完全的自动化，但是可以把大部分的工作交给程序实现，主要通过人机交互的方式，尽量使综合后的结果与手工综合的结果相一致。

At last,a preliminary visual 3D model system for coal seam is established based on coal seem 3D model and using OpenGL and Vc~6.0.Currently a part of research results has been applied to Mine Survey Geological Information System(MSGIS3.0),including constrained triangulation of coal bed suface, coal bed scaleboard contours with fault,part encrypt of contours,excellent turn of triangle,space encrypt,any direction profile of coal bed and so on.

论文的部分研究成果已经应用于煤矿地质测量空间信息系统MSGIS3.0中，主要表现为通过煤层底板表面的约束三角剖分，实现了煤层底板等高线的断层处理、等高线的局部加密、三角形优化、空间插值、任意切割煤层剖面等方面。

DEM is one of the important contents in photogrammetric.

DEM是摄影测量中的一个重要的内容，利用DEM生成等高线已经是摄影测量数字化作业中必不可少的环节，从内插DEM生成的等高线与原始等高。。。

This domination of anafronts was probably due to the fact that the angle between 700 hPa flow and the surface front was very small in the subtropics, so that the surface front usually moved faster than wind speed at the upper levels, resulting in a relative upslope motion of warm air along frontal interface.

分析显示，台湾附近700 hPa等高线多为纬向分布，该层等高线与地面锋面的交角普遍较小，因而该层垂直於地面锋面的风向量不易大於地面锋面移速，气流易出现相对於锋面上滑的情形，形成上滑锋。

The contour map is the easiest to distinguish the height of the terrain. According to the study, it demonstrated that the contour map has to be understudied by learning.But there have not suitable teaching materials to supply learning. However, the conventional map is restricted on the paper; the real world must be displayed by usingthe two-dimension. From this research, using the olography in order to get observe the terrain of stereoscopic vision and analyze the geology.

中文摘要等高线地图是最易判别地形高低的地图，但相关研究中显示等高线图必须经由学习才能看的懂且并无适当的教学媒材及设备供学习，而早期传统的地图受限於纸上，必须将真实的世界以二维的方式来展示，现在如果透过全像立体影像的技术，便可将一般平面影像制作成三维立体影像，以便於做地形的立体观察及地质判释。

By discussing the theory of mapping contour maps, we realize the automatic mapping contour maps including singular and cross-bedded faults.

本文通过探讨等高线的绘制原理，在计算机上实现了单一断层和交叉断层地质等高线图的自动绘制。

Apply the complete and stereo image to the contour map. It can help to differentiate the slop of the contour map. On the other hand, the information and stereo image is helpful to differentiate the depth. It will be a basis to display flat and stereo idea or manufacture the depth of spatial map in the future.

等高线图运用了全像立体影像辅媒材成像时，有助於等高线图坡形的判别，也就是全像立体影像有助於深度的判别，以后可运用在视觉领域里表现平面立体概念时或未来制作成全像地图表现的参考依据。

The two adjacent contour of the elevation difference as the high or away from the contour interval.

相邻两条的等高线的高程差称为等高距或等高线间隔。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
