GIS Day provides an international forum for users of geographic information systems (GIS) technology to demonstrate real-world applications that are making a difference in our society. Join us at the UNC GIS Day events and activities and learn more about how GIS can be used to collect, display and analyze location data:

GIS Three Zeros Scavenger Hunt: Nov. 8-15
Map Competition: Entries due Nov. 12, winners announced Nov. 15
Humanitarian Mapathon: Nov. 15

GIS Three Zeros Scavenger Hunt


Your Mission

To make a crowd-sourced map of the Three Zeros features on our campus.

Find and post pictures of places on campus that illustrate the Three Zeros Environmental Initiative: zero waste to landfills, net zero greenhouse gases, net zero water use. You must find at least one example of each of the Three Zeros. You have one week. Complete your mission and you will be rewarded.

Your Tools

Access the GIS Three Zeros map on your mobile device at, and post oneĀ  example of each of the Three Zeros to the map.

  • Tap the map to get started. Make sure that location services are granted for your browser.
  • Tap the “locate me” circle icon on the left or navigate to the desired location.
  • Tap “OK” at the top right when the marker is in the correct location.
  • Identify which of the Three Zeros you are illustrating, add a photo, your ONYEN and description and hit “Submit”.

Your Reward

Mark one of each of the Three Zeros on the map and claim your prize 11 a.m. to 2 p.m., Nov. 15, at the Sustainability Office table at America Recycles Day in the lobby of the Student Union. Those who complete the mission will also be entered to win one of three Student Stores gift cards, ($15, $25 or $50); winners will be drawn at 4 p.m., Nov. 15, at the Davis Library Research Hub.

The Rules

  • You must find and post one location for each of the three zeros: zero waste to landfills, net zero greenhouse gas emissions, net zero water use, to be eligible for prizes. Entries must be posted by 2 p.m., Nov. 15, 2017.
  • A complete entry includes a location marker, a photo at the location that illustrates one of the Three Zeros, a description of what is sustainable about this feature, and your ONYEN.
  • Posted locations must be on the UNC campus.
  • Winners of the gift card drawing do not need to be present to win; winners will be notified via email by Nov. 16.
  • We reserve the right to remove markers and/or photos that we deem to be inaccurate or inappropriate.

The Clues

Net Zero Water Use: UNC-Chapel Hill works to achieve water-use neutrality by bringing less potable water onto campus and reclaiming non-potable water in cisterns to be used in cooling systems and irrigation, as well as filtering the water that leaves the campus to reduce run-off and improve its quality through stormwater management.

Clues: Look for cisterns, green roofs, rain gardens, stream restoration

Net Zero Greenhouse Gases: UNC works to become greenhouse gas neutral by reducing emissions and improving efficiency on campus, working with state entities to allocate funding and by purchasing offsets.

Clues: Look for solar arrays, buses, bike racks, energy efficient equipment

Zero Waste to Landfills: UNC-Chapel Hill works to reduce waste to landfills by first limitingĀ the amount of waste brought on to campus, and then by recycling and composting waste that leaves the campus. This requires practicing campuswide sustainable materials management and encouraging individual behavior change.

Clues: Look for recycling bins, compost bins, water bottle refill stations, surplus warehouse

These clues are just examples. The idea is to create a crowd-sourced map of all Three Zeros features on campus, so use your creativity to find interesting and original features. The collective map will be displayed here at the end of the scavenger hunt.

The 2017 GIS Scavenger Hunt is brought to you by: Facilities Services Engineering Information Services, the Sustainability Office, Energy Services and Environment, Health and Safety.
