ARCSCAN ARCGIS TUTORIAL PDF
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.

These steps covered the main components of the raster tracing process. The Layer Properties dialog box appears. When you enable classic snapping, it disables the Snapping toolbar’s snapping environment for use in editing. Raster layers must be symbolized as two-color images to use the ArcScan tools and commands.
ArcScan uses the classic editing snapping environment rather than the Snapping toolbar. Setting the raster snapping environment ArcScan is designed to work in conjunction with the ArcMap editing environment and is only active when an edit tuyorial has been started. You need to set some options for snapping while editing and using ArcScan. The ArcScan extension is only active in an edit session. Now that you have set up your raster snapping environment, you are ready to begin tracing the raster cells.
Setting up the ArcScan environment Prerequisite: 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 arcigs pointer around the map. These options are set on the Raster Snapping Options arcsdan box.

You will change the raster symbology from stretched to unique values. Raster snapping requires settings that influence the behavior of the tracing. Once you have finished tracing the raster cells, you can stop editing and complete the exercise by saving your edits.
Click the Editor menu and click Options. Arcbis Unique Values in the Show box. ArcScan makes it easy to create new features from scanned raster images.
Now that you have successfully traced raster cells to create line features, you will create polygon features using the Vectorization Trace tool. You will begin by starting ArcMap and loading a map document that contains the raster dataset tutoiral two layers.
To use ArcScan, you need to enable the extension. 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. Tytorial line feature now represents the exterior boundaries of the scanned parcel lots. Click the Symbology tab on the Layer Properties dialog box. Wrcscan to the ArcScanTrace. Click the Open button on the Standard toolbar. 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.
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.
Exercise 1: Interactive vectorization
ArcScan is designed 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.
In this exercise, you will generate features from a scanned parcel map by interactively tracing raster cells. You will use the Vectorization Trace tool for this step.
