Enable ArcScan

HollySmith — Fri, 01 Nov 2013 09:54:51 GMT

Hi,

I have ArcGIS Basic 10.1 and I want to use ArcScan. This webpage suggests I should have it (http://www.esri.com/software/arcgis/extensions/arcscan)

But...

This webpage suggests it is only for Standard and Advanced (http://www.esriuk.com/software/arcgis/arcgis-for-desktop/extensions/productivity)

I have tried using it but it is not working for me. The whole toolbar is greyed out.

Any clarifications would be great.

Holly

Hi Holly,

Sorry for the delay in responding. Did you enable the extension? See this topic (and the following one): Enabling the ArcScan extension.

I have tried all those pages, but I don't think it is available at Basic level even though some of you documentation suggests it is. I have raised this issue with my local office and hopefully they can give me a definite answer.

I managed to get it working with the help of customer services. I did not have the correct raster format.

ArcScan works with a basic license but you need to enable to extension in Customize> Extenstions.

ESRIs documentation has a few conflicting sentences about ArcScan so when I raised this with customer services they said they would update the documentation across the board.

Hope that helps someone!

I am having a similar issue. I georeferenced a scanned map and converted it to grayscale so that I could place it into two color categories.

What steps did you take to correct the raster format? I am able to vectorize but not edit the raster. Any tips?

Hi Amy,

I'm afraid I can't help, this was 2 years ago and I can't for the life of me remember! Try converting the raster to a .tif or something else?

For ArcScan you need the image to be in binary ie 1 or 0, black or white (2bit). A gray scale image is 8bit.

So if you have a grayscale, you need to segment it into a 2 level image.

Black-and-white imagery is 1-bit (2^^1). Two bits would allow for four states (2^^2). Some gray-scale imagery may be 4-bits (2^^4 = 16 values), and both 4-bit and 8-bit imagery could be colormapped.

Sorry Vince, slight typo and brain fade there....

I segmented the grayscale into a 2 color image. I was able to batch vectorize, but unable to clean up the raster before vectorizing. Do you all know why this is happening and how I can fix it?

I am able to start the editing and raster cleanup session, but when I try to erase the imperfections using the raster painting toolbar, nothing erases. Any idea why?
