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
