TADPOLE Pennsylvania Results

posted Oct 2, 2013, 1:44 PM by   [ updated Feb 12, 2014, 9:24 AM ]

Thanks to our amazing volunteers, the massive dataset in Project TADPOLE Pennsylvania was completely categorized within one month. After going through some of the ambiguous images that you could not agree on and crunching all the numbers, we finally have the results! This first stage of FrackFinder consisted of 2,963 sites permitted for fracking in the Marcellus Shale region of Pennsylvania. Using state drilling data and high resolution aerial photography for 2005, 2008, and 2010, a total of 1,420 well pads were found and mapped -- 60 well pads in 2005, 410 new well pads in 2008, and 950 additional new well pads in 2010. 

Check out our latest article for an in depth look at the TADPOLE Pennsylvania results. For a brief overview, check out the results page.

Progress Update: Project TADPOLE Complete!

Earlier this month we launched Project TADPOLE, the first stage of FrackFinder, a crowdsourced skytruthing project to find, map and track fracking sites beginning with the Marcellus Shale region of Pennsylvania. Thanks to you amazing volunteers, who have observed and classified almost 9,000 images (each one 10 times!) of fracking sites in PA, Project TADPOLE is complete!

We're still crunching the results so hang tight for an announcement on our findings. 

Also, we'll soon be announcing the next stage of FrackFinder!

Progress Update: We can see the finish line!

Jinkies, we're 90% complete! It's only been three weeks and thanks to all of your help, 80,000 tasks have already been completed in FrackFinder: Project TADPOLE! 

As Paul explained on Aug 18th, some volunteers finish before others. So, if you haven't reached the "Job Finished" page you can still help us cross the finish line. 

We are almost there! Keep up the good work and make sure to look out for the upcoming stage of FrackFinder.

Progress Update and Shout Out!

Since the FrackFinder project's official launch just 12 days ago, we've had an impressive response from our volunteers. The first stage has soared from 10% complete to 63%; that's 56,000 times an image was classified!

A special thanks goes to Kevin Hemphill who is leading the pack with 5,877 classified images under his belt!

Keep track of our progress on our FrackFinder page.

The FrackFinder Project has been getting an impressive amount of traffic since our appearance in the Washington Post this weekend. Since then, the progress has jumped from 11% to 38% complete! We now have over 100 volunteers on board! A big thanks goes to all of the skytruthers out there helping us find, map, and track, natural gas fracking sites in the Marcellus Shale region of PA. Keep up the GOOD WORK!

Project TADPOLE is Ready for Take Off

Hi everyone! I'm so excited. TADPOLE, the first stage of FrackFinder, is just about ready for the public. I've uploaded the last of the images and posted an article announcing the launch. There are 2,963 drilling sites across PA. We have high-resolution aerial survey images of each site for 2005, 2008, and 2010. That's 8,889 images to look through, whew! For the sake of accuracy, each image must be classified by ten different people. That means we have almost 90,000 tasks to get through. Thanks to 59 awesome volunteers, who have already submitted almost 9,000 responses, Project TADPOLE is 10% complete. We still have so much to do and we really need your help. Remember that we are still beta-testing FrackFinder and your feedback is of utmost importance! Please try to do at least 200 tasks if you can (that should take less than half an hour) and let us know ( about your experience.  Now go find us some fracking sites!

Last Tuesday I announced that I added over a thousand images to Project TADPOLE. Since then, TADPOLE has jumped from 14 to 21% complete.That may not seem like a huge jump but that's 21% of 1,850 images, each one repeated several times. We now have 51 volunteers and over 8,000 responses!
I want to thank our volunteers again for donating a small chunk of your time and support as we continue to develop our FrackFinder tool in effort to make sense of these massive amounts of drilling data. 
Also, I've upgraded our progress map. It looks so much better now, don't you think? Please help us by sharing with your friends and family and keep up the GOOD WORK!

A Look at Volunteer Feedback Analysis

posted Jul 8, 2013, 9:39 AM by

Two weeks ago, we launched a beta test of the TADPOLE stage of FrackFinder. As of July 1st, we served up 829 images, several times each, covering 20 counties in 3 different years. By that date, 31 volunteers submitted almost 5,000 responses. After analyzing their results, we've concluded that at least 8 out of 10 volunteers agree on a classification with a 99.6% accuracy and over 91% of the time volunteers were 99% accurate. Our volunteers have turned out to be such a great help. We now have 41 volunteers and we hope that as that number grows, we can continue to classify thousands more images while helping the public visualize fracking impact. Learn more about FrackFinder and help us out with Project TADPOLE.

Our volunteer group is now 33 strong, and has completed 64% of the 829 images in Project TADPOLE. Since each image is reviewed multiple times, our fantastic volunteers have submitted 5,270 responses in a week! We still have over 8,000 images to go! That’s 2,963 sites over 3 different years. I've updated the progress map and even got a chance to play with some of our new data - It’s looking good! Keep it up guys and invite your friends to help us out!

Thanks to our growing crowd of volunteers our first set of 829 images is already 60% complete! It's only been a few days since we've launched Project TADPOLE and we have 31 awesome volunteers who have submitted 4,996 responses! (Each image gets reviewed multiple times.) And we've just begun! As Paul mentioned Friday, we have 2,963 sites to look at over 3 different years. That's more than 8,000 images still to go. Thanks for all the help! Keep up the GOOD WORK and spread the word!
