Socio-EconomicCapacity
Ethiopia: 35% undernourished
Global slum population: 1.4 Billion
51.2 Million displaced people in 2013
Namibia’s customary land is no exception
4 billion unrecorded or land interests
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
75% globally without formal land tenure system

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 APPROACHAccuracy = 4-5 cm
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
