Join GeoPhilly for a balloon mapping workshop at the Waterfront during Philly Tech Week! Balloon mapping is a low-cost, easy, and safe way to capture aerial images and stitch them together into a high resolution map. This grassroots technique has been used by journalists and community groups all over the world.

First, we will be meeting on the Delaware River Waterfront (in front of the Independence Seaport Museum) to launch our balloon and camera kits and collect our aerial imagery. This first session will be outdoors in the city, so please dress accordingly with the weather. (If severe rain or wind occur, we will have a rain date on Thursday April 23rd) .

This meetup has a second evening part on the day of the launch where you can help to stitch together the photos taken from the morning or build your own camera rig. You don't need to attend both events, but if you'd like to, you will need RSVP for both. RSVP for both events at geophilly.com.
