Complete the Map: residents can participate in street sign location project

November 13, 2017

MapillaryThe City of Johns Creek is looking to capture street locations and types on local neighborhood streets – and we need your help.
 
Through a partnership between the City and Mapillary, a smartphone app, residents can help collect street sign locations by simply taking pictures of their neighborhood.  Photos can then be uploaded to Mapillary, whose technology analyzes the picture to automatically find street signs.  This sign information is then transmitted to the City, where it helps staff determine the number and type of signs on each street.
 
“With Mapillary and our residents, we can collect the locations of thousands of signs within a matter of a few months,” said Nick O’Day, senior GIS (Geographic Information Systems) manager. “The usual way that cities map signs is by sending teams of staff out to GPS each sign, one at a time, which can take years.”
 
O’Day explained that if a stop sign is knocked down, City crews can refer back to the photos and data captured by Mapillary – which saves money and time – and can begin to fix the issue right away.
 

How it works: 

1. Download the Mapillary app (available on the App Store and Google Play). 
2. Using the app, safely take a photo of your neighborhood from the sidewalk or curb pointed down the road.  The app has an automatic setting that will take photos for you as you walk or bike down the road.
3. Connect your phone to Wi-Fi and upload the photos.
4. Mapillary processes the photos and transmits the sign information to the City.
 
“The added benefit of having these photos is that we can refer back to them when issues arise,” said O’Day. “Having updated photos of every neighborhood road will help staff bring the right tools they need into the field and eliminate duplicate trips.”
 
The GIS Department has created an interactive map that tracks users’ progress across the city. The dashboard also displays a leaderboard where participants track where they rank on how many photos they’ve uploaded through Mapillary.
