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.

Click the Open button on the Standard toolbar.
Therefore, once you have completed your work with ArcScan, you should reenable the Snapping toolbar by unchecking the Use classic snapping box. Qrcgis will use the Vectorization Trace tool for this step. You need to set some options for snapping while editing and using ArcScan. Click the Symbology tab on the Layer Properties dialog box.
The Start Editing command allows you to begin an edit session.
This process can significantly reduce the time it takes you to incorporate raster data into your vector database. The Layer Properties dialog box appears.
In this exercise, you will generate features from a scanned parcel map by interactively tracing raster cells. ArcScan uses the classic editing snapping environment rather than the Snapping toolbar. Now that you have successfully traced raster cells to create line features, you will create polygon features using the Vectorization Trace tool. To use ArcScan, you need to enable the extension.
ArcScan is designed to work in conjunction with the ArcMap editing environment and is only active when an edit session has been started.
Exercise 1: Interactive vectorization
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. Raster snapping requires settings that influence the arcscah of the tracing.
You will change the raster symbology from stretched to unique values. A line feature now represents the exterior boundaries of the scanned parcel lots. These steps covered the main components of the raster tracing process. Now that you have set up your raster snapping environment, you are ready to begin tracing the raster cells.
Exercise 1: Interactive vectorization—Help | ArcGIS Desktop
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. Raster layers must be symbolized as two-color images to use the ArcScan tools and commands. The ArcScan extension is only active in an edit session.
Navigate to the ArcScanTrace. The next exercise will show you how to edit a raster layer and automatically generate features for an entire raster layer using the batch vectorization tools.
When you enable classic snapping, it disables the Snapping toolbar’s snapping environment for use in editing. These options are set on the Raster Snapping Options dialog box.
Setting up the ArcScan environment Prerequisite: Click the Editor menu and tutoral Options. ArcScan makes it titorial to create new features from scanned raster images. 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.
Once you have finished tracing the raster cells, you can stop editing and complete the exercise by saving your edits. Click Unique Values in the Show box. You will begin by starting ArcMap and loading a map document that contains the raster dataset and two layers.
