General | ArcScan for ArcGIS

Can ArcScan for ArcGIS scan my paper maps?
No, ArcScan for ArcGIS works with existing raster images. To use ArcScan for ArcGIS, you must first have your documents scanned to a raster image.
What image formats are supported?

ArcScan for ArcGIS can vectorize any raster format supported by ArcGIS for Desktop as long as it is represented as a bi-level image. This means that the data is symbolized with two unique colors. The Unique Values or Classify rendering options can be used to separate a raster into two colors.

Most scanned documents consist of two colors that delineate the foreground and background values. Typically, the foreground is represented as a dark color, such as black, and the background is represented as a light color, such as white. However, these colors can be reversed or represented by different values. As long as the two colors possess unique values, ArcScan will support vectorization for the current foreground raster cells.

Can I vectorize color maps with ArcScan for ArcGIS?
Yes, you can work with color maps, but the image must first be separated into two classes.
Does ArcScan for ArcGIS support text conversion?
No. ArcScan for ArcGIS does not support optical character recognition.
Can ArcScan for ArcGIS be used while editing vectors?
Yes. All the ArcGIS for Desktop functionality is available while you're using ArcScan for ArcGIS. The ArcGIS for Desktop editing tools complement ArcScan for ArcGIS by allowing you to manipulate vector data.
