Humanitarian Mapathon

at the University of Delaware


Getting Started

  1. Go to and click sign up. Create an account.
  2. Go to the project page and log-in. Click ‘Grant Access’ if another page appears. It will redirect you back to the project page.
  3. Read the instructions carefully. It is important to use the correct imagery and to plot the correct objects. In this case, the default map (Bing Satellite) is best and you will be adding residential areas and buildings to the map. Be sure to follow the links to the
    tracing guide below.
  4. When you are ready to get started, click the Map button. You can choose a white square on the map, then click start mapping. Leave the “iD Editor” selected and click start editor. This will open the standard editor from OpenStreetMap in a new tab. Do not close the original tab. Only edit within the pink box and save your changes frequently. When you save, please use the tag #UDMapathon18 and #mapathon so we can track our contributions. Please don’t hesitate to ask questions if you are not sure about something.
  5. When you are done editing navigate to the original tab and either select “Mark as Completely Mapped” if you have completed the square, or select “Stop Mapping” if you have not completed the square. This will unlock the square so others can edit or validate.
  6. Once you have completed your first square, you can continue mapping other squares. Note: if a square has a lot of work, you can split the task into 4. On the ‘Map’ tab, scroll down and click the ‘Split Task’ button.
