ArcGIS 9.3 矢量数据分析工具使用说明书

Exercise 2: Working with Vector Data in ArcGIS 9.3Step1: Start ArcMap with a new project. Add the following data layers located in c:\REM402\idaho_utmData Layer Description Source Scale Boundary Idaho boundary Inside IdahoCounty Counties of Idaho Inside Idaho Road_100 Highways, roads and trails USGS 1:100,000 Stream_100 Streams USGS 1:100,000 idstwrd_utm Idaho ownership GAP data 1:100,000We will use this base data to create a GIS dataset for the Craig Mountain WildlifeManagement Area located south of Lewiston, Idaho north of the confluence of the Snake and Salmon River.Step 2: Add the Craig Mountain boundary to ArcMap. The boundary is a shape file located in the folder c:\REM402\Craig and named craig_bnd.shpClipCLIP operation: Clip one layer based on another. The CLIP operation works like acookie-cutter. In this exercise we will clip streams, roads and ownership to the boundary of Craig Mountain.Step 5: Use the Clip function to clip out streams (stream_100) and then ownership (idstwrd_utm) using the Craig Mountain boundary as the clip-layer.After you have created the subset layers of roads, streams and ownership you can remove the statewide layers from the project by right-clicking on the layer and select remove. This removes the layer from the map project, however the data file still resides in c:\REM402\Idaho_utm on your computer.Remember to save your work periodically!Xtools extensionXtools is a ‘third party’ extension (not created by ESRI) that can be downloaded at no cost from ESRI(/). Xtools is already on the GIS lab computers. Search on Xtools.After the search is done, select to download Xtools Pro 3.0.The downloaded file is compressed (zip) and must be uncompressed using the WinZip software. You can download WinZip for free from (search on WinZip) if you don’t have this software on your computer.Install the Xtools Pro 3.0 software on your computer.Create a summary table in ArcMapStep 6: Open the theme table for the ownership layer for the Craig Mountain ownership layer. Make sure the area has been updated according to above instructions. The attribute OWNERNAME designates the land-managing entity (BLM, Forest Service, Private etc.) for each one of the over 200 polygons in the table. In the next step you will create a summary table that summarizes the area for each owner category.IntersectThe INTERSECT operation is an overlay analysis between two vector data layers that creates an output data layer that contains the spatial and attribute information from both the input layers.For example, if we intersect the Craig Mountain ownership layer with the Idaho counties we create a layer that contains both the information about ownership and what county each polygon belongs to.Step 8: Use the ArcToolbox Analysis Tools to intersect the Craig Mountain ownership layer with the Idaho counties. Select Analysis Tools – Overlay – Intersect in ArcToolbox.Step 10: Notice how the arcs from the county layer have been incorporated into the ownership layer. The polygons along the county boundary have been split in two – one that resides in Lewis County and one that resides in Nez Perce County.The attribute table for the resulting theme contains information about both ownership and what county each polygon resides in.Proximity AnalysisIn natural resource applications proximity analysis (buffering) is often used to estimate area of riparian zone and habitat along streams. Roads, shorelines and legal boundaries are other features commonly buffered.Point locations can also be buffered. In analyses of wildlife habitat it is often of interest to determine what habitats are within a certain distance of animal observation locations such as nests, foraging areas, etc.In the following exercise you will buffer the streams on Craig Mountain and calculate how much area is within 30 m of a stream.Step 12: Select Analysis Tools – Proximity – Buffer in ArcToolbox. Buffer the streams on Craig Mountain with a 30 m buffer (make sure to buffer the streams on Craig Mountain rather than all of the streams in Idaho!!).Step 13: Use Xtools to update the area for the stream buffer. How much area on Craig Mountain is within 30 m of a stream?Save the project. You will be using this project in the next lesson!Deliverables Lesson 21. A map displaying the land owner categories on Craig Mountain. Also include roads and streams on the map. Include a legible legend, scalebar, northarrow etc.2. The summary table of area in different land ownership created as part of this lab.3. An estimate for how much area is within 30 meters of a stream on Craig Mountain. Please compile all deliverables in ONE document before submitting in Blackboard!。

arcgis矢量化基本操作全解

arcgis矢量化基本操作全解ArcGIS的矢量化操作:一在ArcMAP中进行编辑的流程:1.打开ArcMAP。
2.在ArcCatalog中新建Shapfile图层(点,线,面),并拖入ArcMAP 中。
3.加载地图到ArcMAP中,增加Editor toolbar。
4.在Editor toolbar中点开始编辑,ok,这时你可以开始你的矢量化过程。
Tip:有几个快捷键可以试试,不错的,Z,放大,X,缩小,C,移动,V,显示节点。
最后记得保存结果哦。
二创造新特征:我们可以创造三种主要类型特征:点,线,面。
为了创造线和面,我们首先要创造一个草图,草图由节点和线段组成,如何画点,线,面,我想比较简单(依葫芦画瓢吧!)关键是那几个工具(Sketch construction tools)如何使用:Sketch tool:主要是用来创造线和面特征的节点,在你完成了草图之后,ArcMAP就会增加最后的线段,形成矢量图。
Arc tool:这个主要是帮你创造一个弧段的,选中这个工具后,先在弧段起点点一下,然后在弧段高度方向大致位置点一下(这个点是不可见的,只是给你确定弧段的高度),最后在弧段的终点点一下,就形成一条弧段了。
Direction-distance tool:这个主要是从已知某一个方向和某一个距离来确定一个点。
首先点一个已知方向的点,这是会有一条线出来,你确定好方向后,再点已知距离的点,这是出来一个圆,确定距离后,直线和圆有交点,这就是你要的点,再上面点一下就ok!Distance-distance tool:这个和上面的一样的道理,只是它都用距离来确定一个点,也就是两个圆确定你要的点。
Endpoint arc tool:这也是创造弧段用的,与Arc tool 工具不同的是,它是先在弧段的起点点一下,然后在弧段的终点点一下,再点一个点确定弧段的半径。
个人认为这个工具要比Arc tool工具更精确些。

ESA-E4402B 矢量分析软件操作手册一、计算机、硬件的I/O连接及矢量分析软件安装本软件主要是利用ESA收集到的信号资源通过数字信息的方式与电脑之间进行传输,然后利用电脑的强大计算能力将收集的信号数字信息进行矢量分析及相关操作。
首先要安装I/O软件,放入相应光盘,点击“安装软件”即可自动进入安装程序,安装完毕后,桌面会出现“Agilent Connection Expert”,点击后即进入I/O接口软件界面:点击“USB/GPIB(GPIB0)”选项,即出现:表示硬件还没有连接上计算机,这是需要将ESA和计算机USB口的连接线拿出,在ESA处于关机状态时(连接线请勿热拔插),将ESA和计算机进行连接,连接线连接完成后,启动ESA,然后点击“”,即出现更新窗口,当更新完成后,图标前的小红叉即会变成绿色小钩,表示连接完成!下面介绍本矢量分析软件的安装:首先将相应的光盘放进光驱,出现安装界面后,点击“安装Agilent 89600 VSA”进入正式安装。
安装完成后会在桌面出现“Vector Signal Analyzer”“Spectrum Analyzer”两个图标。
点击第一个即可进入操作软件界面:二、功能按键详解软件操作分为11大项:FILE 、EDIT 、CONTROL 、SOURCE 、INPUT 、MEAS-SETUP 、DISPLAY 、TRACE 、MARKERS 、UTILITIES 、HELP。
①FILE其界面如下:Recall 调用Preset 重新设定Save保存数据,界面如下:Recall:Preset:Save:其中:三项菜单的前四项分别为:(调用/重设/保存)设置、(调用/重设/保存)菜单工具栏、(调用/重设/保存)颜色、字体等外观显示、(调用/重设/保存)光谱图的颜色显示。
State Definitions (State Defs…):规定精确度Recall Recording调出保存的信号图像Preset All将所有设置均重置,恢复原始设置。
Save Recording 保存信号图像。
Copy Trace 为拷贝正处于活动状态(ACTIVE)的某一信号轨迹Remove Register 清除数据寄存器的登陆、注册Print 、Print Setup 、Print Options 为常用打印菜单,打印正处于活动状态ACTIVE轨迹Exit 关闭矢量分析软件②EDIT其界面如下:Undo 取消最后一个已经应用的动作(后退)Copy Trace Data 将当前的轨迹数据写入剪切版Copy Text 将当前文字框里的内容写入剪切版Copy Markers 将当前标记点的数据写入剪切版③CONTROL 其界面如下:Restart 开始一项新测试活动Pause/Single. 暂停/单步执行某一测试Stop 停止当前的测试Disconnect 切断矢量分析软件和硬件之间的通讯联系Record 播放记录的信号Player 打开波形重放特写面板,界面如下:Sweep 切换间断扫描或者连续扫描④SOURCE其界面如下:⑤INPUT其界面如下:Channels 选择1或2输入通道(E4402B只有1个输入通道)Range 为输入信道设定输入范围Coupling 选择交流或直流耦合方式,其总界面如下:其中:Connection 线路种类Reference Impedance 参考阻抗值Trigger 选择触发信号的种类,其界面如下:Data From 选择输入信道信号或者记录的信号:Recording 设置记录参数,界面如下:(图中为记录时需要设置的参数)⑥MeasSetup其界面如下:Frequency Bands 选择合适的频带,有2种方式选择(一般我们选择36MHz-6GHz):Frequency 设置中心频率、带宽的方式;或者是起始频率的方式,界面如下:其中:Frequency step 频率步距Auto Frequency Step 为设置自动设定频率步距,为频带宽度的1/10。
Full Span 设置带宽为最大值From Spec Analyzer 设置矢量分析软件(Vector Signal Analyzer application)的频率参数与频谱分析软件(Spectrum Analyzer)软件相匹配Signal Track 选择根据输入信道的信号频率飘移而自动改变中心频率Time Data 选择在开始频率为0Hz的时候启动分析器的数字本机震荡器,默认为不启动。
