高程数据 meaning in English
altimetric data
altitude figures
Examples
- The disaster prognostication method consists of disaster primary prediction part and disaster correction part . the primary prediction part considers and analyzes various factors which affect the situation of the disaster , to get the flooding area , depth and duration
灾情预测方法分为灾情初步预测和灾情修正两个部分，灾情初步预测部分依据高程数据建立dem模型，综合考虑和分析影响灾情的若干因素，得到淹没的区域、深度和持续时间。 - Large - scale digital elevation model is foundation of spatial information in cybercity and provides a great deal of information for 2d map and 3d model of cybercity , and it provides a kind of efficient method to manage , store and maintain a great many data of cities " elevation
大比例尺数字高程模型是数字城市空间信息的基础，它提供了数字城市中的二维地图和三维城市模型信息，为海量的城市高程数据提供了管理、存储和维护的有效手段。 - Visualization of terrain information is playing a key role in many applications such as flight simulation , 3d geographic information system , etc . however , with the rapid development of the remote sense and satellite technology , people expect to investigate or view larger terrain regions with finer precision , which inevitably leads to the real time visualization of huge terrain dataset
地形信息的可视化在实时仿真和地理信息可视化系统中占有十分重要的地位。然而随着遥感技术，卫星技术的发展，使得获取高分辨率的数字几何高程数据以及影像纹理数据成为可能，人们希望观察更广范围的地形，对地形的实时绘制提出了更高的要求。 - So the conception of los ( light of sign ) is introduced into the equivalent treatment of treat avoidance in order to take account of terrain - shiled affection . finally , a new genetic algorithm is developed in this paper . three new arithmetic operators which are introduced into the algorithm are recording better , restoration and reconstruction . what ' s more , the known arithmetic operators are also improved in order to expand searching scope
因此在对威胁回避的等效处理上，本文引进了los (视线)概念进行地形可视概率计算，把威胁回避等效为地形回避，然后把等效地形数据离散化叠加到原先的地形高程数据中，这样就充分地考虑了地形的屏蔽作用。 - The geological factors are important besides them , which are related to the loess landslide and evolution of gullies , specially for bedrock folds , bedrock joints and loess joints . in field , the data of the bedrock elevation in the three sheets combined with the research from south to north lively were got by gps12xlc pocket locator , the type and its evolution of bedrock , loess landslides and distribution of hydrographical net were explored too . at office , the synthetic analysis and contrast were used including the simulating analysis about the data by mapinfo 6 . 5 , software of gis , discussion and communication with experts , in order to demonstrate and reveal the rules between the loess landforms and its pale bedrock landforms and the impact of structure on erosion interiorly in shaan bei
在野外，以代表调查区和路线调查相结合的方法，利用gps12xc型手提式定位仪采集基底高程数据，实地观察基底地层产态变化规律和特征，观察黄土地貌、黄土崩塌、水系展布及土壤侵蚀等与地质构造之间的关系；在室内主要进行综合分析与对比，利用gis系统的mapinfo6 . 5软件对采集数据模拟分析，并将认识成果与其他专家学者进行交流和探讨，从而论证和揭示陕北黄土地貌南北纵向分异与基底古样式关系特征及水土流失与构造因素之间的内在规律。
