Innovations In Boundary mapping: Namibia, Customary land & Uav’s Annual world bank conference on land and poverty March 2015 Mukendwa Mumbone, Rohan Bennett, Markus gerke, Walter Volkmann
Overview Introduction Customary Land mapping: Namibia (Problem) UAV as alternative mapping tool Methodology Pilot Test- Freedom Square Informal Settlement Lessons and conclusions
Effects Problem Causes Food Insecurity Inadequate Housing Ethiopia: 35% undernourished Food Insecurity Inadequate Housing Disputes and conflict 51.2 Million displaced people in 2013 Global slum population: 1.4 Billion Land Tenure Insecurity 75% globally without formal land tenure system Namibia’s customary land is no exception Problem Land Information 4 billion unrecorded or land interests Causes Land Policies Land Laws Land Institutions Land Processes Cadastral / Registration Tools Socio-Economic Capacity Do not exist Do not recognize all tenures (e.g. customary) Are corrupted and suffer inertia Are neither customer nor market oriented Are costly, take too long, and accuracy-centric Is growing, but, skilled workers still lacking Adapted from Bennett, R.M., (2015), H2020 Brainstorming Meeting, February 18th, ITC, Netherlands
Customary Land mapping: Namibia Aerial Photographs Limited availability Out-dated High acquisition costs Survey Standards High accuracy expectation Merger to national deeds system threats
UAV as alternative tool Can UAVs be used in customary land parcel boundaries? Meet required legal requirements (if any)? Meet technical requirements?
Methodology Literature Workflow Design Pilot Test
Pilot Test GCP Placement Image Capture Image Processing (Pix4DMapper) Ortho Image Production Accuracy assessment
Validation of new approach Accuracy = 4-5 cm Validation of new approach
vectorisation Community gathering Parcel identification Vectorise on-screen in high resolution (Zoom and Pan – better than printing) Identify roads, fences, hedges, houses, foot paths (guidance) Data can be used to create cadastral map of area Data can be used on land right certificate
Lessons and Discussions UAV technology supported by law, subject to certain restrictions Relevant laws silent about survey standards Vectorising parcels digitally reduces need for printing
Procedure executable, good quality images produced Suitable for first registration UAV produces high accuracy survey 4-5 cm
