Creation of geodata

In partnership with local mappers, LLg implements free, simple and robust geomatics solutions to create geodata in the field or via imagery, ensuring their quality and long-term preservation.

LLg promotes the creation and use of open data, in particular that from the OpenStreetMap project.

Enhancing geodata

LLg knows how to extract, process, transform and add value to geographic data to enable access or redistribution according to the interoperability standards specific to geodata, using open-source tools and respecting licenses and ISO standards. Whether it’s a partner’s business data or data from OpenStreetMap.

LLg can also distribute them through its Open Francophone Spatial Data Infrastructure (IFL).

Training in free geomatics and open data

LLg trains emerging players in geomatics 2.0 in French-speaking countries in the South, including those with no theoretical or practical knowledge of geomatics, in Open Source geomatics methodologies and tools, through training workshops adapted to each context, involving local skills and promoting replication.

LLg provides training in OpenStreetMap, QGIS, Open Data Kit, webmaps and the geOrchestra Spatial Data Infrastructure.

Mentoring and local empowerment programs

In addition to technical training in OpenStreetMap and open-source geomatics, LLg has always supported the emergence and growth of collectives within young open-source players, to enable them to publicize their activities, structure themselves or set up projects.

To achieve this, LLg has designed a range of original programs and materials covering the areas needed for local empowerment, inspired by feedback from other territories.


LLg produces all kinds of open-licensed documentation on open geomatics, from step-by-step guides for beginners to state of the art or summaries of the issues at stake in the field, using different types of media.

Since 2014, LLg has also been developing a documentary common covering all the stakes and technical aspects of free geomatics and open data.
