ArcGIS make use of CAD tracing process teacher assigned a job, less than ten minutes to complete the workload Ninety-five percent! ! !

EDITORIAL

After coming Cheng Xiaojun should all be on the teacher's class digital topographic survey of the students, I believe that drawing is not very easy to do the job right (CAD great God skip), I also worked hard to complete drawings, and only learned arcscan, innovation under the guidance of the project and reminded his teammates to complete the rapid tracing, wave now share with you.

Tools needed

Look at the title we all know it, first, ArcGIS , second, is the CAD .

Specific steps

In order to improve the collection efficiency and the quality of digitized, ArcGIS ArcScan extension module is provided. It can easily create new features from scanned raster images by ArcScan module, which also gives us an opportunity .

1. Start ArcMap, create a new template
2. The folder where the files you want to connect to describe the picture folder, then right after layer, select Add Data, the tif format images added to it, if you pop out of what to say to build the pyramids, select No, out of the second a pop select OK. After determining, open the directory, right-click the link to the folder, select Create a new document management system database . Built after the database, right-click the database, select New, feature class , give the name in pop elements, and then select the type of feature line feature , click 'Next' until completion, repeat the operation, the establishment of surface elements . (Steps below) can begin to do after setting ArcScan work environment .
3. To use ArcScan, you first need to load this extension. Click on the main menu [Custom] -> [extension], select [ArcScan], then click [Close]. Click on the main menu [Custom] -> [Toolbar] -> [ArcScan] to show the toolbar ArcScan
   followed ArcScan only binary image processing, and therefore should raster image to a binary image. In the ArcMap table of contents, click [topographic map screen drawing operations .tif] -> [Property], [in] the Layer Properties dialog box, click the symbol [System] tab, [show] box, click [ The only value], press OK to return. Third, ArcScan must be used with ArcMap editing environment, and only after starting the edit session will be active.
   The above three necessary conditions ArcScan active, please remember.

4. Then set the grid snapping environment . When you edit and use ArcScan, also you need to set capture options. Click [Editor] -> [Options] -> [General] tab, select [] using classic snapping. When classic snapping is enabled, it will disable the editor used [to capture] toolbar capture environment. Therefore, the use of ArcScan work could be canceled to use the classic catch [] re-enable [capture] toolbar. Click OK to return. Click [Editor] -> [edit] beginning
in order to ensure ArcScan track track, you need to set the grid to capture [] mode. Click ArcScan] [raster snapping options toolbar button, and open the [capture] dialog grid, the maximum line width value to [20], this setting ensures that capture relatively large raster cell . Click OK to return. Click [Editor] -> [Capture] -> [capture] window, pop-up [environment] capture window, click the plus sign next to the [grid] to expand it, select centerline [], [intersection] , [end], [corner] option, after completion close the window. So far, work on preparation of ArcScan on the well, following the official start of automatic vectorization .
5. Click vectorization] -> [Vector] settings, open the "Vectorization Settings" dialog box, for vectorization settings to be modified to ensure the best results when generating features. The maximum line width [] change the value to 20, the compression [tolerance] change the value to 0.1, click [Application] to be updated. Click vectorization] -> [View] to display preview the batch vectorization effect, if not satisfied, you can continue to fine-tune the vectorization settings. If satisfied with the [Close] dialog box. The final step in the batch vectorization process is to generate features. Click vectorization] -> [generate] elements and polygon features created before clicking the right button and select [data], see [Export to CAD]. In the window that pops up, click on the [down arrow] input elements, the two elements are selected, click OK
When the export is complete, open your DWG file storage folder, opened with CAD, and then adjust the color, you get something as shown.

Written in the last

This can only be done ninety-five percent of the work, will probably line sketched out, and because the text is not a vector, the effect is not very good, you can delete the word through raster cleanup, and then add their own in CAD . Other details still need everyone to modify, after all, this is not artificial intelligence, can not nothing to trace. My job is a tracing of his own description . Thank you, for the first time to write a blog, not so good, I hope you criticism. Xie Xiexiang brother's idea!
