For more than 20 years, the Pikine and Guédawiaye departments in the region of Dakar have been faced with recurrent flooding. Beginning in 2005, serious measures to curb the phenomenon have been taken by the President Abdoulaye Wade. Realities in the field and the consequences of flooding on local populations led to the completion of these measures using a cartographic analysis of the situation.

In September of 2009, IGN France International offered to complete a detailed analysis of the topography of flooded areas, in partnership with the Senegalese company GAI. This project was made up of an historical study and a detailed analysis of the topography of the  flooded and flood-prone areas, as well as the completion of a GIS. It was carried out for the Jaxaay plan (Project for the construction of social housing and the prevention of flooding and shanty towns).

  EUROSION, European Union

The goal of the EUROSION project was to establish recommandations in terms of policies for sustainable development of costal erosion based on the knowledge of successful experiences. IGN France International was chosen for the conception and development of an information system on European coasts which would allow to localise and rank the vulnerable zones.

The approach proposed by IGN France International relies on an inventory of existing data on a European, national or regional level, over all main topics that may influence positively or negatively the coastal erosion process. Based on this preliminary inventory, the existing data sets are ranked depending on their pertinence to the problem, the flexibility of their analysis, their quality, their exhaustivity and their accessibility. The data sets that are well adapted are acquired and organised in layers within the Geographic Information System (GIS). Others are completed to make sure that the geographic coverage is large enough.

The SIIRM (Spatial Infrastructure Reconstruction Monitoring) project began following the tsunami that devastated South East Asia in December 2004. For the French consortium, the task at hand was to provide the Sri-Lankan authorities with up-to-date cartographic data and GIS solutions in the urban planning field.  
The consortium, composed of the Groupe FIT, FIT Conseil and IGN France International provided data that formed the basis for cartographic applications and GIS oriented toward the reconstruction effort and the development of urban priority zones, notably in the eastern and southern parts of the island.
SIIRM allowed the Sri Lankan authorities to implement a spatial data infrastructure that was a key element of the post-tsunami management, all with the help of the technical support provided by the French consortium.

Implemented in 2004, the CORINE Colombia project began over the entire Rio Magdalena hydrolgical basin (more than 234,000 km²). It allowed the estimation of the link between the amount of carbon present in vegetation coverage as well as the variety between time and space while respecting the KYOTO protocol.
The CORINE Colombia database, completed in the beginning of 2007, has become a reference for the establishment of new ecosystem databases.

  ADAPTATION OF THE CORINE NOMENCLATURE, San Salvador, Guatemala, Honduras

Since 1999, IGN France International has been trying to sensibilise Central American and Caribbean countries to the interest of the CORINE system. A feasibility study over the Rio Lempa basin was completed in order to better adapt the nomenclature to the regional specificities and to launch environmental applications based on this database.

This project aimed to improve the institutional and administrative abilities of the country at a local, regional and national level, while facilitating the implementation of European legislation by the provision of environmental databases and the creation of a dedicated extranet portal.
It was conducted for the Ministry for the Environment and Sustainable Development (MEDD) and regional environmental protection agencies.
