Last month I was lucky enough to be invited to the USGS’s Digital Mapping Techniques (DMT) conference. Unless you do geologic mapping this conference is likely not on your radar, but suffice to say it worth the effort to get to Moscow, Idaho on many counts. One is that I met Andrew Wunderlich, who gave a great and detailed presentation on how he has been migrating a base of Adobe Illustrator files to ArcGIS. This question has appeared on Ask a Cartographer a number of times, where we’ve given a rather general answer. Andrew got into the details, I know more than a few of your are faced with this task, so here is a link to the Powerpoint from Andrew’s presentation. Andrew is also working on some additional notes and we will let you know via the comments on this posting when those are available.
