The paper introduces the latest development and application in the production of engineering survey technology. GPS allocation technology and the combination of GPS and total station have been widely used in plane surveying of control survey. Electron distance trigonometric leveling can replace third and fourth-order spirit leveling in vertical survey. Data collection, processing and drawing by total station has achieved automation and integration in topographic survey, etc.

随着工程测量技术的发展，控制测量中平面测量已广泛地采用了GPS定位技术、GPS与全站仪相结合的技术，高程测量中电子测距三角高程能代替三、四等几何水准测量；地形图测绘中，实现了全站仪从野外数据采集、处理到绘图过程的自动化和一体化；摄影测量和高分辨率遥感技术在大比例尺地形测图中的应用等。

Point/Snap toggle Allows you to choose between Point Mode (exact point of cursor click determines point selected) or Snap Mode (point is determined by, or "snaps to," nearest endpoint of an existing item to cursor click) while drawing .

点击/捕捉切换当你正在绘图的时候，允许你在 Point Mode 点模式（精确选择鼠标指针所单击的点位置）和 Snap Mode 捕捉模式（点位置的选择被确定在距离指针单击位置最近的一个现有内容上的一个距离指针单击位置最近的端点）之间自由切换

In order to draw a photorealistic surface, Bidirectional Texture Functions, a 6D texture function which extends Bidirectional Reflectance Distribution Function to include the self-shadowing, self-occlusion and inter-reflection effects, has been mentioned frequently in recent years. Its main drawback is its massive data size. To solve this, Spatial Bidirectional Reflectance Function techniques compress BTFs into reflectance model parameters. However, SBRDF cannot producethe self-shadowing and self-occlusion effects in real-world surface geometry. This work is aimed to this drawback. I find how self-shadowing and self-occlusion affect the surface by additional physical-based analysis. And I rely on two physical phenomena to divide self-shadowing and self-occlusion into two independent effects. First, self-shadowing is view independent. Second, self-occlusion is independent of lighting direction changes. After these analyses, I use SBRDF and additional self-shadowing and self-occlusion I found to render a photorealistic surface as non-compressed BTFs doing.

为了把物体表面呈现的更真实，六维函数BTFs ( Bidirectional Texture Functions)目前已经被使用的相当频繁，但BTFs的资料量实在太大而没办法直接使用，为了解决资料庞大的问题，传统的SBRDF以逼近光反射模型参数，来达到资料压缩的效果，但是SBRDF对於表面的凹凸所产生的阴影及遮蔽，不能达到逼真的呈现，为了改善这个问题，我们选择从物理方面，找出资料中阴影和遮蔽等属於表面几何的资料并去除，使参数更正确，同时利用两个物理现象去区分阴影及遮蔽为两个互不干涉资料，第一是阴影不会因视角不同而改变，第二是遮蔽不因光线方向不同而改变，经过这些分析，我可以利用SBRDF加上附加的阴影及遮蔽两种独立的效应，来达到彷佛跟未压缩过的BTFs一样的真实绘图。
