UAV for participatory mapping in Haiti

Transcription

1 UAV for participatory mapping in Haiti

2 OpenStreetMap - OSM Use of GPS and satellite imagery (Bing) to build the map

3 History January 12 th, 2010 : earthquake - intensity deads, 1.5 million of IDP Creation of OpenStreetMap (OSM) communities ; COSMHA : Community OSM Haiti : - Port-au-Prince : COSMHA-PaP - Saint-Marc : COSMHA-STM - North - North-East : COSMHA-NNE Support of different organizations : HOT/Cap103, IOM, Drone Adventure, OSM-Fr, CartONG, and OSM volunteers contributors! participatory mapping OSM project in Haiti One week before the earthquake One week after the earthquake

4 TITRE DE LA SLIDE A brand new tool : the UAV (Unmanned Aerial Vehicle) UAV, what for? Take aerial images with high resolution (4-10 cm/pix) Create an accurate Digital Elevation Model (15-20 cm) Top vision - high resolution Various uses of UAVs : Natural hazards Disaster Risk Reduction (DRR) Inspection Topographic surveys of landfills Agriculture Mining / quarrying Environmental Management Hydrological analyzes Research and rescue missions Coastal surveillance Monitoring of hazardous areas or difficult to access Monitoring of refugee camps (IDP) DEM

5 TITRE DE LA SLIDE A brand new tool : the UAV (Unmanned Aerial Vehicle) Canaan, November 2010 Time evolution Updated image The same area in June 2010 (5 months before)

6 TITRE DE LA SLIDE A new tool : the UAV (Unmanned Aerial Vehicle) Lines levels with 1 meter of resolution Digital Elevation Model (DEM)

7 UAV for participatory mapping in Haiti UAV deployable for participatory mapping like OSM : Project with C.OSM.HA CartONG OSM Fr in May-June 2014 Bing satellite imagery UAV image

8 TITRE DE LA SLIDE Mission of May-June flights (70 sq km) with 3 communities : - 18 over PaP, Rivière Grise (30 sq km, 8 cm/pix) - 9 over St-Marc (14 sq km, 6-10 cm/pix) - 15 over North & Nort-East departments

10 TITRE DE LA SLIDE Mission of May-June 2014 Knowing the territory : the first step to act for the communities Aerial imagery to uphold the field actors vision of the territory and to put the communities at the center UAV is a uniting tool that brings communities together Train the communities to map and use the UAV Participatory mapping makes possible to update geographic information and plan interventions together Participative mapping is a powerful tool to enhance the communities' resilience facing natural disasters, but also to engage a dynamic for the local development of the territory. It induces change from and with the local communities, despite difficulties 42 flights (70 sq km) with 3 communities : - 18 over PaP, Rivière Grise (30 sq km, 8 cm/pix) - 9 over St-Marc (14 sq km, 6-10 cm/pix) - 15 over North & Nort-East departments Salon des Soidarités Juin 2014

11 TITRE DE LA SLIDE Example of community work Cleaning of wastewater canals Soley Leve, quartier by quartier change on the ground, in Cité Soleil. Blocks organize to improve their own neighborhood. This map traces their progress,,,

14 TITRE DE LA SLIDE Appendix #1 Main features of «ebee» UAV 2 functions : Aerial image high resolution (4-10 cm/pix) Accurate Digital Elevation Model (15-20 cm) Flights supervised and secured by remote control with computer Manual take-off Battery life of 30 min : o 1 sq km of coverage with 4 cm / pix (altitude of 130 m) o 2 sq km of coverage with 8 cm / pix (altitude of 260 m) Wind resistant up to 12 m/s (45 km/h) Lightweight (700g), no crash risk (security) Range up to 3 km, depending of the field Easy to use, although requires a minimal experience

15 TITRE DE LA SLIDE Appendix #2 Technical strenghts and weaknesses of the UAV Strenghts : Quick intervention, even on cloudy days Response to specific requests Setting of the flight characteristics Ability to change the flight plan during a mission Automated post-processing to build DEM & mosaic picture Weaknesses : Superficy cover restricted Wind < 12 m/s Landing fragilised Not static more suitable for imagery than video
