But I also live in the real world. I make maps and print them. I export them to PDF. I exchange data with other users and organizations — most of them casual GIS users. And these users (and their applications) only know and understand the shapefile.
Casual GIS users will continue to use the shapefile because it is simple, convenient, and universally supported. It just works. To call for the abolition of the shapefile is akin to calling for the abolition of the .xls(x) format on the grounds that people erroneously use it in lieu of “legitimate” databases. Millions of people.
Let’s be real and call off the shapefile vendetta. There is room (and need) in the geoverse for both PostGIS and shapefile. Why not just buy yourself a “Postgres is my databae” or “I ❤ .SHP” t-shirt to show where you stand? You’ll look hip, whichever you choose.
