The Potential3.0 team are both Imagery and UAV experts andexperimented OSM contributors that developped their expertise inHaiti following the 2010 earthquake. Fred Moine and Presler Jean UAVproject started with the Sandy Hurricane in 2012. Since then, theyorganized regular UAV small civil drones flights, they worked withhydrologists and collaborated with municipalities to identify themost at-risk homes in places such as Rivière Grise and Canaan.Municipalities programmes have been set up for the relocation of mostat risk people.
Quite acoincidence, Fred Moine arrived in Port-au-Prince a few days beforethe Matthew hurricane for a new UAV mission. He did not know thatthis would be a Long Journey to provide technical support directly tothe Haiti Civil protection and the CNIGS agency and organize UAVmissions in such a difficult context it is presently in thesouth-west peninsula of Haiti.
With some 80% of houses severly damaged or destructed in some areas hit by the hurricane, a vast Program of Reconstruction is organized by the Haitian government, the Inter-American Development Bank (IDB) and the World Bank. Since it is not possible to send teams in the cities with the hunger and difficult access, these organizations count on Post-disaster evaluations from UAV to evaluate the damages and evaluate the financial effort for this response.  

         Two weeks ago, Fred Moine, Xavier Lamure-Tardieu and Presler Jean started to organize the Response in Port-au-Prince with the Haiti OSM community the humanitarian response from the field. Long standing Leaders of Activations with experience in the development of the Haitian OSM community over the last years, we joined-in to support at distance our Haitian collegues in such difficult days. Boy scout Association of Haiti joined also to help the response and arranged last week Fred's helicopter flight to Jeremie.  They are also sollicited to contact people in various areas and identify information usefull for the response.
 
 Experimented OSM contributors needed for the response 
    To make a success of this action we need the participation of experimented OSM contributors from around the world as we did for other responses in the past.   
  This MapAction map shows the zones with highest winds and most of the damages. The population in these areas is particularly at risk with the difficulty to join them, to provide water, food and sanitation and take care of the wounded. http://reliefweb.int/map/haiti/haiti-hurricane-matthew-general-overview-and-track-6-oct-2016 
   The priority zone to look at is west of the RN 7, the main road going from Les Cayes to Jeremie.  Also on the north of the peninsula Nippes department, areas going east up to Baradères have to be prioritized. A priority task for now is to revise all roads in these zones to assure that all the villages are connected to the highway network.    
   Experimented OSM contributors are also needed to evaluate the damages from the UAV images and support the Reconstruction projects. 
 
   Post-disaster tasks   
    A "Premiere" in such humanitarian responses with the presence of Potential3.0.  We already have UAV images for 5 square km (Jeremie + part of Les Cayes).  An other 5km2 should be ready within 24 hours to complete the coverage of Les Cayes. The haitian government agencies and international organizations are quite impressed to have access to such accurate images early in the response. We should give a hugh to the haitian volunteers and Potential3.0 for their efforts and reconfort them, let them find the energy to continue to respond to such a disaster. 
   Fot this Matthews response, Fred accompanied the Civil Protection team last week in Jeremie. As a fallen bridge stopped any circulation by road, they travelled by helicopter and worked in difficult conditions without communication and power. Fred succeeded to bring back near infrared images of Jeremie while the other camera was on repair. 

This weekend, the 15, Fred an Presler organized UAV flights over Les Cayes. They brought back the 16 the images to Port-au-Prince and processed them rapidly, sticking the images together and georeferencing them. As he did for many OSM responses, Jean-Guilhem Cailton processed also rapidly produncing tiles and transferrting these on the OSM-Fr server. The 17, 5km2 of images were already available. Quite impressive!  
 The haitian government officials and the assessment teams from the IDB and World Bank were astonished to see the operational capacity of this NGO run by volunteers, their flexibility, rapidity and technical mastering of such a complex operation.      

  The post-diasaster tasks are at http://taches.francophonelibre.org/ and the instructions in both english and french. Private tasks have been setup to assure that experienced contributors only participate to the mapping.     
   There is a task presently to complete the evaluation for Jeremie. Once completed, the focus will move to Les Cayes.  UAV NIR image of Jeremie https://umap.openstreetmap.fr/fr/map/images-uav-jeremie_107330#20/18.65028/-74.11740  UAV Color image of Jeremy Port

 If you want to help, please contact us and provide us your osm account to access the task and contribute. 
          Please come and help.
