You can take any image, and you can vectorize it with ArcScan. This means you’ll spend less time digitizing and more time doing other. Quick-start tutorial. • Exercise 1: Raster tracing. • Exercise 2: Batch vectorization. 2. ArcScan for ArcGIS software has the tools you need to convert your scanned.

The ArcScan extension is only active in an edit session. Setting up the ArcScan environment Prerequisite: A line feature now represents the exterior boundaries of the scanned parcel lots. Therefore, once you have completed your work with ArcScan, you should reenable the Snapping toolbar by unchecking the Use classic snapping box. You need to set some options for snapping while editing and using ArcScan. Raster layers must be symbolized as two-color images to use the ArcScan tools and commands.

Click Unique Values in the Show box.

Now that you have set up your raster snapping environment, you are ready to begin tracing the raster cells. Click the Symbology tab on the Layer Properties dialog box. ArcScan is designed to work in conjunction with the ArcMap editing environment and is only active when an edit session has been started. Once you have finished tracing the raster cells, you can stop editing and complete the exercise by saving your edits.


This process can significantly reduce the time it takes you to incorporate raster data into your vector database. Click the Open button on the Standard toolbar. You will use the Vectorization Trace tool for this step. These options are set on the Raster Snapping Options dialog box. The next exercise will show you how to edit a raster layer and automatically generate features for an entire raster layer using the zrcgis vectorization tools.

ArcScan uses the classic editing snapping acrscan rather than the Snapping toolbar.

Exercise 1: Interactive vectorization

You will begin by starting ArcMap and tutlrial a map document that contains the raster dataset and two layers. Raster snapping requires settings that influence the behavior of the tracing.

Setting the raster snapping environment ArcScan is designed to work in conjunction with the ArcMap editing environment and is only active when an edit session has been started. Now, you need to turn on SnapTips, which are pop-up messages that give you information on the type of snapping that is active as you move your pointer around the map.


Exercise 1: Interactive vectorization—Help | ArcGIS Desktop

Navigate to the ArcScanTrace. Arfgis makes it easy to create new features from scanned raster images. Now that you have successfully traced raster cells to arsccan line features, you will create polygon features using the Vectorization Trace tool. In this exercise, you will generate features from a scanned parcel map by interactively tracing raster cells.

The Start Editing command allows you to begin an edit session. In this exercise you learned how to set the raster snapping options and environment, snap to raster cells, and trace raster cells to create new line and polygon features. When you enable classic snapping, it disables the Snapping toolbar’s snapping environment for use in editing.

These steps covered the main components of the raster tracing process. Click the Editor menu and click Options. To use Wrcgis, you need to enable the extension. You will change the raster symbology from stretched to unique values. The Layer Properties dialog box appears.
