Click Bookmarks and click Trace lines to set the current view to the edit area of the exercise. You will use the Vectorization Trace tool for this step. Now that you have set up your raster snapping environment, you are ready to begin tracing the raster cells. Click the Editor menu, point to Snapping, then click Options.Ĭreating line features by tracing raster cells. 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. Click the Editor menu and click Options. You need to set some options for snapping while editing and using ArcScan. Click the Symbology tab on the Layer Properties dialog box.ĪrcScan is designed to work in conjunction with the ArcMap editing environment and is only active when an edit session has been started. Right-click the ParcelScan.img raster layer in the ArcMap table of contents and click Properties. You will change the raster symbology from stretched to unique values. Raster layers must be symbolized as two-color images to use the ArcScan tools and commands. Click the Customize menu, click Extensions, check ArcScan, then click Close. To use ArcScan, you need to enable the extension. Navigate to the ArcScanTrace.mxd map document in the ArcScan directory where you installed the tutorial data and select it (C:\ArcGIS\ArcTutor is the default location). Click the Open button on the Standard toolbar. In addition, start ArcMap and add the Editor and ArcScan toolbars to the display. You need to have the ArcScan for ArcGIS extension installed and registered. Setting up the ArcScan environment Prerequisite: You will begin by starting ArcMap and loading a map document that contains the raster dataset and two layers. In this exercise, you will generate features from a scanned parcel map by interactively tracing raster cells. This process can significantly reduce the time it takes you to incorporate raster data into your vector database. Online courses connect you to the global village.Exercise 1: Interactive vectorization Complexity: Beginner Data Requirement: ArcGIS Tutorial Data for DesktopĪrcScan makes it easy to create new features from scanned raster images. Online courses have financial benefits.ĥ. Online courses promote life-long learning.Ĥ. Online courses give you real-world skills.ģ. Online courses are convenient and flexibilityĢ. What are the advantages of online school?ġ. It can be hard for some students to stay motivated when they'd rather be doing something else. Online courses require more self-motivation.
