IGN France International provided a CAMA type application to the department of land assessment in Namibia. Wishing to establish a transparent and fair land tax based solely on "commercial" agricultural land, the local authorities wanted to implement a land assessment application that was adapted to the specificities of their local context.

IGN France International also provided and installed the material necessary for the training of different users.

 IGN France International is a member of the IAAO (International Association of Assessing officers), whose vocation is to promote innovation and excellence concerning land assessment administration, property assessment and land taxation policies.
