Celebrate GIS Day with a UD Mapathon!

Why Mapathon?

We are excited to continue mapping in the spirit of past mapathon events at Earth Day 2020, GIS Day 2019, Earth Day 2019, GIS Day 2018 and Geoweek 2017! Mapathons are our way of getting more people involved, promoting free and open data, and garnering excitement about mapping. It is a way of ‘flexing our muscle’, that is to show we can make a difference through our network of volunteers.

GIS Day 2020 Project

The project we will be is working on for the GIS Day Map-a-thon is #9455 COVID-19 East Canje/E.C. Berb – Coast, Guyana. Before participating please read the projects directions carefully. For help getting setting please visit our the map-a-thons Getting Started guide page.


Mapping is done with OpenStreetMap, a free and online mapping tool. Projects are organized by the Humanitarian OpenStreetMap Team (HOT) using a tasking manager called the HOT Tasking Manager. In a project, the area is broken into small squares which a volunteer can choose to edit. Once the volunteer starts working on a square, the square is locked from editing by users in the tasking manager. This way, two people do not edit the same area and overwrite each other’s work.

Since OpenStreetMap (OSM) can be used to add data to maps worldwide, this Mapathon gives us the opportunity to provide help from the comfort and safety of our homes. It’s easy, fast, and a great way to contribute to humanitarian efforts this GIS Day!

In this reference guide, you will find information on how to use OSM to map roads, buildings, and elements.

Map from the convenience of home on your own time! If you need help getting started you can join us on Zoom between 4PM to 7PM on November 18th. 

Thank you to our sponsors and organizers!

This event was organized by Epsilon Eta and is being sponsored by The Geology Club, IT, Library, Museums, & Press, Students for the Environment, and the Earth, Ocean, and Environment Club.
