Geomatics emerges as a transversal domain that draws on previously highly compartmentalised disciplines such as topometry, cartography, geodesy, photogrammetry and IT. The great originality of geomatics therefore lies not so much in the new concepts manipulated, but in the way these concepts are integrated, thanks to the development of information technology. In a context of globalisation and accelerated exchange of information, the Pan-Latin Terminology Network (REALITER) in collaboration with the Office québécois de la langue française (OQLF) has promoted the development of the Pan-Latin Geomatics Lexicon. Starting from the French language, the Lexicon collects terms in six Romance languages (Italian, Catalan, Spanish, French, Galician, Portuguese) and in English. In the case of Spanish, the equivalents used in Mexico are also present.
