I have some strange fascination with old Encarta and other CD-ROM titles from 20+ years ago, and how they relate to today. How did encyclopedias and atlas products work then, and how was it different to today? I made a video so you can see how it worked.
Encarta Atlas’ main limitation was storage. So there’s only secondary roads in places, and the aerial imagery is 1 or 10 miles per pixel instead of the high resolution we’re used to today.
Still, most of the UIUX hasn’t changed between then and now. It’s fair to call Encarta Atlas the Google Maps of its time – while Encarta didn’t support shift-drag to zoom to an area… neither does Google today. That’s the only real thing missing on either platform.
