Hurricane Matthew as predicted caused catastrophic damage to Haiti that is
still recovering from the 2010 earthquake. The main damage is located in
western Haiti in Grand Anse, Sud, and Nippes Departments. Current estimates
are that over 800 people have died, thousands are in shelters, and 80% of
all structures are damaged.[1][2]

The HOT community rallied to meet the challenges of mapping this large
area. Just a few months ago and prior to the storm as part of a malaria
campaign Missing Maps lead by Clinton Health Access Initiative and HOT
remotely mapped all structures in the heavily damaged Grand Anse
department. As the storm predictions became dire and in the last few days
over 1,000 mappers contributed over 1.2 million edits, adding 180,000
buildings to the map concentrated in the most affected areas. [2] Together
you have mapped entire cities such as Jereme, Les Cayes, and Petit-Goave.[3]

The mapping is not done however. As humanitarian groups are able to conduct
assessments and plan relief efforts our mapping must continue. Digital
Globe generously donated recent pre-event imagery and is actively tasking
new areas for post-event imagery.[4] New tasks are created almost every day
as new information comes in from the field and new imagery comes online.

I've seen the difference that these maps can make to humanitarian work in
the field first hand. I strongly encourage everyone to map a little bit
this weekend. I also encourage you to find a few friends and teach them how
to map as well.[5]

Lastly, many people on this list actively deploy to disasters. If you need
help or would like HOT to direct its amazing volunteers to map an area of
interest not yet covered, please send a note to activation at hotosm.org. If
you would like to help manage the activation please feel free to join us on
Slack.[7]
