You will begin by starting ArcMap and loading a map ardscan that contains the raster dataset and arccscan layers. Therefore, once you have completed your work with ArcScan, you should reenable the Snapping toolbar by unchecking the Use classic snapping box.

Now that you have set up your raster snapping environment, you are ready to begin tracing the raster cells. A line feature now represents the exterior boundaries of the scanned parcel lots. You will use the Vectorization Trace tool for this step.

Now that you have successfully traced raster cells to create line features, you will create polygon features using the Vectorization Trace tool. Click the Editor menu and click Options. In this exercise you learned how to set the raster snapping options and environment, snap tutorila raster cells, and trace raster cells to create new line and polygon features.


The ArcScan extension is only active in an edit session. Setting the raster snapping environment Arcgus is designed to work in conjunction with the ArcMap editing environment and is only active when an edit session has been started. When you enable classic snapping, it disables the Snapping toolbar’s snapping environment for use in editing. The Start Editing command allows you to begin an edit session. Raster snapping requires settings that influence the behavior of the tracing.

Click the Open button on the Standard toolbar.

Once you have finished tracing the raster cells, you can stop editing and complete the exercise by saving your edits. 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.

You will change the raster symbology from stretched to unique values. ArcScan makes it easy to create new features from scanned raster images.

Exercise 1: Interactive vectorization

ArcScan uses the classic editing snapping environment rather than the Snapping toolbar. To use ArcScan, you need to enable the extension.


Click Unique Values in the Show box. Setting up the ArcScan environment Prerequisite: ArcScan is designed to work in conjunction with the ArcMap editing environment and is only active when an edit session has been started.

This process can significantly reduce the time it takes you to incorporate raster data into your vector database. You need to set some options for snapping while editing tutorual using ArcScan.

These steps covered the main components of the raster tracing process. Click the Symbology tab on the Layer Properties dialog box.

Navigate to the ArcScanTrace. Raster layers must be symbolized as two-color images to use the ArcScan tools and commands.

The Layer Properties dialog box appears. In this exercise, you will generate features from a scanned parcel map by interactively tracing raster cells. 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 batch vectorization tools.
