Zanzibar Mapping Initiative Z M I Project Overview My name is Mohammed ZAHRAN from the Commission for Lands Zanzibar, today I respresent The Zanzibar Mapping Initiative, along with my two colleagues, Khairaat KHAMIS our highly skilled drone operator from the State University of Zanzibar, and Yves Barthelemy our project coordinator Mohammed ZAHRAN - Commission for Lands Zanzibar 2. Khairaat KHAMIS – State University of Zanzibar 3. Yves BARTHÉLEMY - OBSCOM

ZANZIBAR MAPPING INITIATIVE Project objective : Updating aerial imagery of zanzibar using drones (mostly Ebee) Imagery will be made available to all actors under OpenData License and will serve as a basis for updating OpenStreetMap. Main outputs: 7 cm : over Rural Areas. 2.5 cm over some Urban Areas High Accuracy Land Use available in Open Data. The projects main objective is to use UAVs to capture high resolution aerial Imagery that will be used to produce an up to date digital map of Zanzibar Project objective : Updating aerial imagery of zanzibar using drones (mostly Ebee) Imagery will be made available to all actors under OpenData License and will serve as a basis for updating OpenStreetMap. Main outputs: 7 cm : over Rural Areas. 2.5 cm over some Urban Areas High Accuracy Land Use available in Open Data.

Context Activities Overview 2 islands 2300 km²: UNGUJA (1200 km²) and PEMBA (1100 km²). Activities Overview Activity 0 : Training (GIS, Emotion, Pix4D, Drone operations) Activity 1: Image acquisition campaign “Zanzibar Mission” Activity 2: Image processing: Activity 3: Digitization Project scope is the two island of Unguja 1200 Square Kilometres and Pemba 1100 Square Kilometres There are Four Main Activities involved Activity 0 : Training (GIS, Emotion, Pix4D, Drone operations) Activity 1: Image acquisition campaign “Zanzibar Mission” covering Unguja and Pemba using several drones during an intensive drone campaign. Activity 2: Image processing: Creating ortho-imagery of the whole Unguja island Creating 3D models Activity 3: Using the information generated Based on the drone imagery produced, intensive digitization of features in OpenStreetMap. Based on imagery generated, improvement of environmental baseline information

Zoning system = 9 km² zones 239 zones in Unguja 182 zones in PEMBA The Island are Zoned with 3 by 3 Kilometre grids to produce 239 zones in Unguja 182 zones in PEMBA

Operations SUPPORT JOINT TEAMS SUZA/ZANSEA Drone LAB COLA Students Processing Center Drone Workshop Osm map parties COLA Authorizations Quality Control Surveyors Drone Teams (2 to 4) 1 car 3 drones 3 Members Flight Planner Logistician Data Management The Operations are coordinated through the State University, by providing the energetic workforce for workflow management and data processing, The Commission for Lands provides Technical Surveyors and facilitate authorizations

Interactive Map synchronized with Spreadsheet GIS Mapping Operations GoogleSpreadsheet logsheet Interactive Map synchronized with Spreadsheet There is an interactive grid on the map that enable tracking the progress of the field operations GIS Mapping

Dissemination Data accessible on ZANSEA Geonode. Data is made accessible through ZANSEA Geonode

Coastal mapping : sand, coral, … Here is an example of coastal image showing sand and coral

Human-use : tourism activity along the coast We can sense accurately the tourism hotels and get exact property or land coverage

Human activities along the coast Some human activities like sports grounds

Socio-Economic Features We can locate some local fisheries activites

Coastal environment: Mangroves Some costal mangrove forest monitoring

Kibele Landfill site Monitor Landfill sites

ZMI/Conclusion At the end of the project, COLA will have UNGUJA and PEMBA covered with 7 and 2.5 cm High Resolution Imagery to create a Base Map and its Digital Cadastre SUZA will have: Highly skilled staff at SUZA in : GIS, Drone Mapping, Photogrammetry, 3D, Geospatial image servers, … Students enrolled in GIS activities. An up and running Drone Lab at SUZA within the GIS Centre. A success story for all partners involved.
