Need help vectorizing pdf

Question

I am working on a project for the local police department and have to vectorize a map of the police sectors.  I have converted it from pdf to jpg.  When I attempt to use arcscan the raster does not appear in the drop down menu, when I go through ERDAS>convert>raster to features I receive an error that the raster does not contain thematic data.  Am I missing something that should be obvious?  Anyone that has any suggestions it would be greatly appreciated

I would try the software Able2Extract. It does make a fairly good job converting PDF to dxf or dgn. It's the most consistent solution I ever found for this task.

ArcScan is limited to binary (0,1) images thus your solution for converting PDF to JPG won't work 😞

If you raster is single band 1 bit, just use the Unique Values renderer.  Otherwise you can change to the Classified renderer, and make 2 classes.

Hi mw95yv,

Please watch the following Web Help videos, and let me know if this does not address the issue.

The video has me going in the right direction, how do you symbolize rasters as bi-level?  I think that I understand what to do after that but getting there is the problem
