Map Auctions Collections, and Effects
The Wall Street Journal today has an article on map auctions coming up in December titled, “Here be Dragons – and Map Lovers“. The maps, globes, and other cartographic items they list sell for several thousand to several million dollars. One collector says that he spends up to 10% of his income on map collecting. According to the Barry Lawrence Ruderman Antique Maps Inc. most map collectors start out by collecting themed maps such as a specific geographic region, historical time period, or even type of cartographic style. Geographaphicus, an antique map blog, says that one of the most frequent questions they get asked is how to determine if a map is authentic or a fake. This is a problem for collectors and also a staple plot device for literary novels and movies.
Antique maps have always made GIS users whistful and there are many requests on-line for how-tos on making a GIS map have more of the cartographic effect of an antique one, such as this post by James Fee from 2006 on creating historic map effects. The Yale Map Library has a dated but thorough document on how to do Classic Cartographic Techniques in ArcMap. The real question is though, how will online and interactive maps stand up to antiquity? Will collectors be bidding on printed out versions of the maps we make today?
