Senegal/ PROCASEF: implementation of the geodetic reference network

The project to modernise and rehabilitate Senegal’s geodetic infrastructure is part of the Land Registry and Security Project (PROCASEF), which aims to put in place land management tools throughout the country.

The land reform currently underway in Senegal is a key commitment on the part of the government, and must be based on a modern, reliable and accurate geodetic reference framework for the entire country, as such an infrastructure is essential to guarantee the geospatial integrity of surveying and positioning work.

This geodetic reference network is being implemented by the IGN FI – Leica Geosystems consortium, and includes the installation of 16 new permanent GNSS stations, linked to a control centre. This network of modern stations throughout Senegal will form the national reference and will be linked to the international system.

In parallel, the project includes the rehabilitation of the existing 1st and 2nd order geodetic networks, the setting up of a geodetic database and a user portal, and a transfer of skills to the technical staff who will be in charge of monitoring.

The GNSS observation mission of the materialised networks is currently underway, with dynamic teams in the field (IGN FI, ANAT, CADASTRE), following a rigorous methodology that is essential to guarantee the accuracy and reliability of the new reference. The GNSS observation sessions are carried out using high-precision equipment, and are doubled for each of the 160 points on the rehabilitated national network. Radio spots accompany the missions to raise public awareness.
