Hey everyone,

I did a few searches but didn't turn anything up.

I have the task of digitizing some old maps of China, quite detailed actually. They are in a digital format, my plan was to georeference the images in PCI Geomatica with user entered co-ordinates. I have used this technique before to georeference air photo imagery. Is there a better way?
I have access to PCI geomatica, ArcGIS and Adobe Illustrator.

Thanks,
Matt

Digitising can be done with any of the three. But you need to consider what the client wants in the end. Is it just the map or he wants it integrated later in some GIS product. If the purpose is cartography only then Illustrator would be the best, WYSWYG, because digitisation in ArcGIS and then converting to Illustrtor for printing would require more time. The warping or rubber sheeting in ArcGIS would again add some distortions to the map, so you need to look at the final product to be delivered.

I would recommend using ArcScan from ESRI.

You can always try it for free!

Hi Matt,

I would suggest to carry out your excercise in ArcGIS, B'coz its a globally recognised format, and geo-referencing accuracy can always be checked with its RMS value. We have done hundreds,thousands of historical map data digitization,so i think its better if you proceeed with arcgis..Irrespective of integrating the map to any external source, conversion is also pretty easy.

Thanks
