1. 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

2. Overview
Introduction
Customary Land mapping: Namibia (Problem)
UAV as alternative mapping tool
Methodology
Pilot Test- Freedom Square Informal Settlement
Lessons and conclusions

3. 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

4. Customary Land mapping: Namibia
Aerial Photographs
Limited availability
Out-dated
High acquisition costs
Survey Standards
High accuracy expectation
Merger to national deeds system threats

5. UAV as alternative tool
Can UAVs be used in customary land parcel boundaries?
Meet required legal requirements (if any)?
Meet technical requirements?

6. Methodology
Literature
Workflow Design
Pilot Test

8. Pilot Test GCP Placement Image Capture Image Processing (Pix4DMapper)
Ortho Image Production
Accuracy assessment

9. Validation of new approach
Accuracy = 4-5 cm
Validation of new approach

10. 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

12. 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

13. Procedure executable, good quality images produced
Suitable for first registration
UAV produces high accuracy survey 4-5 cm
