Jerry's map - now available as an interactive map

I've blogged about the remarkable work of Jerry Gretzinger before - but not for 14 years.

Back in 2011, I became aware of Jerry's work to create a massive map based on imagination. Dan Raven Ellison sent me a link to a Vimeo film.

Over 60 years ago, in 1963, Jerry drew a map of his fictional city Wybourne on a piece of A4 paper. 

When it was complete, he continued on more pieces of paper, sticking them all together to create a whole new world. When the map got really big, Jerry started to revise it, using aprocess involving a pack of cards to decidewhat amends should be made. In 1983 he put it in the attic and stopped making it, until it was discovered by his son.

In 2011, I was able to contact Jerry and he provided me with some answers to some questions which ended up in GA Magazine - that section is shown to the right here from the Spring 2012 issue. Inspired by the map, I purchased a piece of the map on eBay. Jerry was selling off pieces back then to fund the map's development.

They returned in 2014 and now you can buy some pieces of his generative art.

Earlier today, I saw that Keir Clarke on the wonderful Google Maps Mania blog had shared a new rendering of Jerry's map as an interactive map.

Jerry's Map consists of more than 4,000 individual 8-by-10-inch panels arranged in a giant circular formation. Together they form a sprawling imaginary world that sits somewhere between a city plan, an abstract artwork, and a living organism.

It's been made with Leaflet. Pan and zoom....

Watch the video of Jerry here.
