Fields Mapping in Rural Areas in Mali

Choisy-Le-Roi is a French town near Paris. It runs a cooperation program with Tringa Marena, a rural municipality in Mali, 90 kilometers East of Kayes. Any visitor to Tringa Marena, quickly gets a sense of the challenges its population has to face, but getting from that feeling to concrete steps that have actual positive impact that meets the needs of the people requires a detailed understanding of the local context. To that purpose, mapping is the paramount tool but, in such a remote region, cartography at the level of detail required to plan efficient action lacks severely. The use of geographical data would enable the Malian local partner authority with more efficient resource allocation for its projects portfolio of water access, health access and schools.

So, in September 2017, Openstreetmap Mali carried out a mapping project in Tringa, in collaboration with the Malian Association of Solidarity and International Cooperation for the Development and the town of Choisy-le-Roi The project focused on five villages highlighted on this map

In classic Openstreetmap methodology, the data collection began with the use of orbital imagery to map major features visible from the air (roads, residential land use, outline of public buildings etc.) and thus lay the foundations for fieldwork. We organized this stage using two tasking manager projects (1 and 2). With the support of contributors around the world, those two projects were completed in two days.

That set the stage for the critical step of garnishing the map with the fine-grained detail that makes it useful for planning – and that can only happen on the ground: only looking directly in front building and asking its inhabitants will let one know its purpose and its name. Covering the whole zone took us two days of intense walking around, accompanied by AMSCID agents with local knowledge. Geolocated photographs (some of them stored in Mapillary) completed our collection.

We had opportunity to interact with the customary authorities to inform them of the project, its objectives and benefits – and also to learn more about the traditions and customs of those villages, critical steps to not only foster acceptance of the project but furthermore to let the inhabitants appropriate its goals.






We went around the five villages and met the inhabitants who welcomed us while informing us about their living conditions and especially the disinterest of the national government and the lack of adequate infrastructures for the education of the children and particularly that of the girls.






The achievement of this project, a second of its kind, was a nice experience for us – not only because we completed our goals of collecting solid geographic data to support local development initiatives, but also because of the enthusiastic population among which honing our methodology has been a real pleasure.

In early March, I was honored to give a presentation of this campaign to an audience composed of the political and administrative authorities of this rural municipality and of the Circle of Yelemané, a delegation of the French Agency for Development (AFD) and officials of the Malian Association for Solidarity and International Cooperation ASMCID, in the partnership house in Bamako.


We thank the EOF (Espace Openstreetmap Francophone) and Les Libres Géographes for their daily friendly support, the Organisation Internationale de la Francophonie (OIF) which let us benefit from their capacity building workshops, AMSCID for their trust and support, the Humanitarian Openstreetmap Team (HOT) for their microgrant and support and the Openstreetmap contributors around the world who gave us a hand… We are always humbled by how much support we get from the whole community and we are thankful to them for the success of our actions !

Cartographie des Acteurs de l’Innovation Numérique , CarteInnov


Dans le cadre de la gestion du projet de Cartographie des Acteurs de l’Innovation Numérique, Carteinnov, un projet initié et soutenu par l’Organisation Internationale de la Francophonie dans 14 Pays d’Afrique Francophones, dont mon Pays, le Mali, j’ai eu à mener des collectes d’informations sur le terrain et des entretiens avec des responsables de  différentes structures concernées par ledit projet au Mali des son lancement en Août 2016 à maintenant dans le but de leur faire part de son objectif et de le faire adhérer .

L’un des objectif principaux du projet est la mise en relation de ces différentes structures de differents pays oeuvrant dans le même domaine, chose tres important dans un monde en pleine mutation.


J’ai eu également à organiser beaucoup d’ateliers de sensibilisation autours de ce projet avec l’implication de ces acteurs qui œuvrent et  font la promotion du numérique et qui font des investissement dans ce sens.












Dans le but d’initier les acteurs à l’édition d’informations supplémentaires au sujet de leurs structures, J’ai eu à organiser des sessions de présentation et de démonstration avec l’éditeur spécial de production de carte du projet  le 30 Novembre 2017 dans le local de l’Agence des Technologies de l’information et de la communication, AGETIC.



Il cinquantaine de personnes, composées d’étudiants, de travailleurs et Chef de Division de l’Agetic, de Journalistes, d’ingénieurs en Informatiques,  ont pris part à cet évènement.


l’évènement a débuté par le mot de bienvenue de Directeur Adjoint de l’Agetic, qui a profité de saluer les initiateurs du projet.

Ce fut ensuite la séance de présentation des objectifs du projet, les pays et structures concernées,  les initiateurs et les exécutants locaux et visualisation des données à l’aide de Umap.

La seconde session fut consacrée à la démonstration de l’editeur MapContrib qui a permis aux participants de savoir éditer de nouvelles, de modifier et d’ajouter des informations supplémentaires à la carte.

Cette séance a laissé la place aux questions réponses et échanges sur l’importance de la production et réutilisation des Données Ouvertes pour le Développement Durable, ce qui nous a emmené à introduire OpenStreetMap, étant donné qu’il est la plateforme qui héberge les données du projet dans le but de permettre le libre accès et le partage des données grâce à la licence ODBL.


Les participants furent émerveillés par le projet et ont exprimé leurs satisfaction mais ont aussi fait des propositions dans le sens de la protection des données pour garantir la fiabilité des informations.

OSM & GIS Training for Geography students

From 22 to 23 December, workshops were held in OpenStreetMap and Geographic Information System for  Geography students at the University of Bamako, in Jokkolabs at the High School of Trade and Technology, ESCT.

These workshops focused on the introduction to the OpenStreetMap techniques and the use of OSM data on geographic information processing software.
This workshops began at 9 o’clock on 22 December with the presentation of participants composed of students and professionals working in the Geographic Information Systems.
Sessions of the morning focused on the generic introduction of the OpenStreetMap project, the presentation and demonstration of data collection mobile applications.

The afternoon sessions, was focused on the implementation of the JOSM software and editing of the data collected in the field and also, on the mapping coordination tool,

Around 5 pm, this very rich first day with ended with excited participants.
The second day began with the recapitulation of the previous sessions, followed by the study of tools for exporting osm data, including http://export.hotosm.org/ and http://overpass-nnturbo.eu /.

Participants were taken to extract data on Bamako city and to use them on https://umap.openstreetmap.fr/en/

And on Qgis. At the end of this last session on this free software of geographical information Systems, participants produced very beautiful Maps, as you will see on these pictures

The workshops ended at 5 pm and participants expressed their thanks, appreciation and satisfaction to the facilitators and also promise to become regular contributors and use the osm data to solve populations needs.
