#794 - Missing Maps: Dominica

Nothing has happened yet.

The Missing Maps project aims to map the most vulnerable places in the world (affected by humanitarian crises: disease epidemics, conflict, natural disasters, poverty, environmental crises). Building on HOT's disaster preparedness projects, the Missing Maps tasks facilitate pre-emptive mapping of priority countries to better facilitate disaster response, medical activities and resource allocation when crises occur.

Tropical storm Erika became the fifth named storm of this year’s Atlantic Hurricane Season on August 24, 2015. Erika began impacting the CDEMA Participating States from Wednesday, August 26 and degenerated to a trough of low pressure on Saturday, August 29, 2015.

The centre of Tropical Storm Erika passed about 90 miles to the North of Dominica at its nearest point with the storm producing intense rainfall across the island. The Canefield Airport near the capital of Roseau, Dominica, recorded 12.64 inches of rain in a 12-hour period from Erika on Thursday, August 27. This resulted in severe flooding and landslides and wide spread damage across the island.

To support relieve efforts on the island a more detailed map of the island is requested.

When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".

Priority Areas

Start with high priority areas that are marked in the red squares After completion of high priority areas, focus on coastal areas and along major roads. There is a lot of jungle/bush in the middle of the island, which should get less priorty.

Start mapping

Please click on a square to start mapping.

Use Bing imagery for this project.

Cloud cover

There's a lot of cloud cover on some parts of the island. If you can't fully map a tile because of cloud cover than add "unable to complete due to cloud cover" to your comment and mark the task as done


Simply digitise the outline of all buildings in each square and make sure you either SQUARE (shortcut key = 'S' in iD editor) the corners of square/rectangular buildings.

Roads that lead to buildings should be traced and tagged as stated below.

Building tags:

  • building=building (in iD)
  • building=yes (in JOSM).

Road tags

  • highway=residential (in iD and JOSM)
