maptimeLEX May 2015 Meetup

Don’t adjust your glasses! Indeed, you’re seeing things correctly. Because of a last-minute change in April Mike Dillion’s introduction to TurfJS is the topic for our May meetup. TurfJS is a powerful, new JavaScript library for doing geospatial analysis in the browser. We’ll be meeting at 6:45 PM on Wednesday, April 15th at CirrusMio (154 Constitution St).

Grow the buffest buffers, aggregate point data to the hexiest hex-bins, and find the centroid you’re looking for all without expensive, resource-intensive GIS software. Through a project code named “Astroturf Ninja,” Mike will get us going with TurfJS.

Astroturf + ninja

While a basic understanding of GIS and JavaScript concepts won’t hurt, newbies of all stripes are welcome. RSVP on Eventbrite and let’s tread the greener pasture together and learn TurfJS!


  • What: Geospatial Analysis with TurfJS
  • When: 6:45-9:00, Wednesday, May 20th
  • Where: CirrusMio, 154 Constitution St, Lexington, KY 40507
  • Who: Anyone who wants to learn a new way to do simple to complex geospatial analysis in their browser using JavaScript!

In line with the general spirit of maptime, we want this and all our meetups to be welcoming to people of all backgrounds and skill levels. If you’re more used to desktop GIS with ESRI products or QGIS, come out and learn! If you’re JavaScript wizard, we want you too! A laptop will be necessary for following along. If you don’t have access to one, feel free to contact us and we’ll work to hook you up with a computer for the meetup.

If you have any questions or concerns, don’t hesitate to drop us an email or contact us via twitter. We look forward to seeing you on 5/20!
