Upgrading of general map and modernisation of the national mapping institute (IGM), MALI
The update of base maps in Mali had not been carried out since serval decades and the geographic institute of Mali (IGM), due to a lack of technical means, was no longer able to fully ensure its sovereign missions of production, dissemination and conservation of a reference map. The project to update the 1:200,000 scale topographic map as well as modernise the mapping institute was created from these needs. The project’s aim was produce a data base and a new topographic map of the whole country at a scale of 1:200,000, to provide a homogenous and a coherent cartographic reference available for various sectors (transport, infrastructure, forests, mines, statistics, agriculture, energy, tourism, Office du Niger…) which could be used as a platform for exchanges and integration of data and information coming from these sector.

Main objectives of the project
- Obtain structured data: the topographic data is collected together in a model that enables them to be used as a GIS and information from this data (metadata) is now available
- Possess a new series of 1:200,000 topographic maps for the whole country
- Possess a set of map-derived digital products and services: a geoportal and a geocatalogue enabling the data produced by the project to be diffused
- Possess a modern geographic institute equipped with high-performance tools and competent personnel
