ArcScan uses the classic editing snapping environment rather than the Snapping toolbar. You will use the Vectorization Trace tool for this step. 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.

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

The Start Editing command allows acscan to begin an edit session. Click the Open button on the Standard toolbar. You need to set some options for snapping while editing and using ArcScan.

Exercise 1: Interactive vectorization

These steps covered the main components of the raster tracing process. The ArcScan extension is only active in an edit session. In this exercise, you will generate features from a scanned parcel map by interactively tracing raster cells. Now that you have set up your raster snapping environment, you are ready to begin tracing the raster cells. 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.


Click the Symbology tab on the Layer Properties dialog box. Setting the raster snapping environment ArcScan is arcacan to work in conjunction with the ArcMap editing environment and is only active when an edit session has been started. Therefore, once you have completed your work with ArcScan, you should reenable the Snapping toolbar by unchecking the Use classic snapping box.

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 behavior of the tracing. Setting tutorisl the ArcScan environment Prerequisite: The Layer Properties dialog box appears.

This process can significantly reduce the time it takes you to incorporate raster data into your vector database.

These options are set on the Raster Snapping Options dialog box. Click the Editor menu and click Options. A line arcgid now represents the exterior boundaries of arxscan scanned parcel lots. When you enable classic snapping, it disables the Snapping toolbar’s snapping environment for use in editing. Navigate to the ArcScanTrace. Once you have finished tracing the raster cells, you can stop editing and complete the exercise by saving your edits. You will begin by starting ArcMap and loading a map document that contains the raster dataset and two layers.

ArcScan is designed to work in conjunction with the ArcMap editing environment and is only active when an edit session has been started. Click Unique Values in the Show box. You will change the raster symbology from stretched to unique values.

ArcScan makes it easy to create new features from scanned raster images. To use ArcScan, you need to enable the extension.

Now that you have successfully traced raster cells to create line features, you will create polygon features using the Vectorization Trace tool.
