This project consists of updating the entire country’s map coverage at a scale of 1:200:000, in order to make a coherent national cartographic reference available for various actors (Infrastructure, Land management, statistics, rural development, social equipment, environment …). This reference will allow exchanges of data coming from various sources.

The database that is produced must be compatible with the national land cover database in order to make a set of various information layers available that should be consistent and complementary. In order to guaranty the success of the capacity building phase, the entire production must be carried out on site, at the IGB premises, and by IGB’s staff, with a methodology that has been set up by IGN France International, with equipment whose configuration has been defined by IGN FI, and with three years of technical assistance and support from IGN FI’s experts.

The Serbian Geodetic Institute (RGZ) in charge of establishing cadastre in Serbia was asked to become the centre for Geographic Information in the Serbian Republic in order to meet the European Union SDI standards that will be in place by 2015. To do so, a collaboration was set between RGZ and the consortium composed of EADS Astrium and IGN France International, allowing the delivery of highly technological components, an unique transfer of knowledge and experience destined to elaborate this Serbian Spatial data infrastructure centre capable of producing, updating, organising and disseminating geographic data for the sake of Serbian citizens, as well as the public and private sectors.

IGN France International was awarded a European Union tender in December 2010 on the completion of an urban mapping database covering 7 of the country’s cities (Dakar, Thiès, Mbour, Saly, Louga, Kaolack, and Saint-Louis).

The country’s main towns are lacking in both databases and accurate and up-to-date cartography. This project, lasting 25 months, will thus provide the National Sewerage Office with relevant information useful for the sustainable development of these areas which are under a lot of pressure to the National Sewerage Office of Senegal, who chose the priority cities. The project was based on entirely local production with a strong skills transfer component carried out by the IGN France agents.

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).

The goal of this project was to redo Senegal's maps at a scale of 1:200.000 over the entirety of the country. Fusioned SPOT and LANDSAT images were used to create the new cartography, now available in paper versions (printing of the maps in quadricrhome as well as in a digital format on CD Rom (raster image format).

Entirely acheived on site, the project called upon traditional cartographic techniques as well as more modern IGN techniques. The project was preceeded by the creation of a new first-rate geodetic network and the online availability of the "Circé©" coordinate transformation software.

The DTGC (Direction des Travaux géographiques et cartographiques) did not pass up the opportunity to improve its equipment, reinforce the technical level of its personnel, to improve its production capacities and to organise future maintenance.
