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
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.”
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
● How could we ensure the quality of what was produced?
● Crowdsource, more people needed than the 100 APPs
● Animation and Training within Lesotho
Solutions
OpenStreetMap
Task Manager
Field Papers - Survey at Lencer’s GapPrint 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 the features recorded in the survey
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.

Crowdsource to #MapLesotho
Osmose error checker finds over 70 error types
Training TrainersTraining and engagement team of four persons formed within the APPs who are interested in bringing other APPs and non APPs involved

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
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
Case Study 2:
The Golden Hour
60 minute drive time from sample of
hospitals and health facilities
Case Study 3: A thing as lovely as a treeLesotho needs to prevent any diminution of its agricultural land. One aspect of this is soil erosion. Overgrazing in the highlands has reduced attenuation
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.

● 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
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.

#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
● Encourage a culture of publication for all Planning staff
