About MAPfrappe Content last updated 14 Apr 2015.

Welcome to MAPfrappe, my interactive site for cartographic “mixtures.” I started this site in 2006 to help me explore various geographic relationships. Presently the site contains two interactive pages:

As time goes by, I hope to add other interactive mapping pages to this site.

I hope you like what I've got so far. Please send comments to me at the address at the bottom of this page.

What’s “frappe”?

Frappé is the French word for “shaken.” It’s also a blended coffee beverage invented in Greece. Wikipedia discusses several uses of the word here.

People in the Boston area also refer to a milkshake as a “frappe.” They pronounce it “frap,” to rhyme with “map.” I invite visitors to pronounce “MAPfrappe” any way they like, but I pronounce it like the Boston folk, as “map-frap.”
