Most countries have a national association of surveyors.
FIG, the International Federation of Surveyors, links all these associations together into an international organisation. FIG is a non-governmental organisation whose purpose is to support international collaboration and understanding between surveyors all over the world, for the progress of surveying in all its fields and applications. It seeks to stimulate scientific and technical development through the exchange of ideas and experiences. FIG was founded in 1878 with seven member associations. In the beginning of 1995 FIG has sixty six member associations from sixty two countries all over the world.
