2. Overview
- Explain the genesis of the Mapping Project
- Explain what the project has done to date
- Case Studies of how the #MapLesotho data is vital for
Planning in Lesotho
- Our ambitions for the next phase

3. REQUEST FOR ASSISTANCE
2012
“.....we would like to be assisted
with training in GIS. The Division
has computers but neither a
licence nor sufficient skills to
take advantage of open source
software on the internet.”

4. Challenges since 2013
● No budget for software associated with the project
● ARCGIS licenses expired in 2012 and 2013
● Land Administration Authority charging for data, not updating data
● Training aimed at Assistant Physical Planners (APPs) - not under the direct
control of the Ministry
● Perception that work was done only when we were present for training
● Access to the internet and suitable laptops at District Government offices
● While the APPs were spread out they had no access to surveying equipment

5. Solutions

6. OpenStreetMap

7. Task
Manager

8. Field Papers - Survey at Lencer’s Gap
Print the existing openstreetmap
and walk around noting features
not visible from the satellite
imagery.
Examples:
● Fences
● Upper floors of buildings
● Building type
● Access point
Scan the image and tag or draw

9. Drive or Walk around the
street and capture images
using the Mapillary mobile
phone application. The
pictures help us see more
that can be added to the
map.

10. QGIS

11. MapBox

12. Crowdsource to #MapLesotho

13. Osmose error checker
finds over 70 error
types

16. Training Trainers
Training and
engagement team of
four persons formed
within the APPs
who are interested
in bringing other
APPs and non APPs
involved

17. Make a map of Lesotho
- Opensource
- Crowdsource
- Analysis
- Social Media
- Integrated technology
Easy to remember, descriptive
and realistic

22. Case Study 1: Is Lesotho building in the wrong places?
OpenStreetMap maps buildings. It is used to map rivers, streams and canals. So are
the buildings too close to the waterbodies?
In 2007 the country experienced terrible flooding, which had a human, agricultural
and infrastructural cost
What follows is an example of how we downloaded the building data and looked at
it in the context of the waterbodies
I can also give you an indication of whether the buildings more recently built are
making the situation worse or better

25. Case Study 2: The Golden Hour
Lesotho, like every country in the world
has a challenge with where health services
are located. Outside cities or far from
population centres pose risks for people
who need emergency care

26. Case Study 2:
The Golden Hour
60 minute drive time
from sample of
hospitals and
health facilities

27. Case Study 3: A thing as lovely as a tree
Lesotho needs to prevent any diminution of its
agricultural land. One aspect of this is soil erosion.
Overgrazing in the highlands has reduced
attenuation

28. Case Study 4: Profiling a Town
Quick use case to show how useful
information derived from OSM can be
quickly used to determine the focus of
further planning studies.

35. ● Two million edits by
Tshedy!!!
● Mappers 2-6 not
Mosotho
● Approximately 70% of
the mapping is done
from outside Lesotho
● Lesotho will shortly have
more nodes than South
Africa and Egypt

37. Phase 2
The Mapping is now
adding finesse to the
drawn features, improving
road and building shapes
and adding unmapped
things like farmland and
forests.
Lesotho is divided up into
its ten districts and one
city, so eleven tasks
altogether.

40. #MapLesotho requirements for success
● Expand basic mapping training to non-trained district APPs
● Land Survey Division, Regional and District Planners and Maseru City
Council to get analysis training or advanced mapping training
● Provide QGIS analysis training for a capable group
● Make provisions for regular gatherings to maintain skills
● Review the situation with access to laptops and office wifi for all
Planning staff
● Link together mapping and surveying with Planning and Planning
reform
