APSG (Americas Petrioleum Survey Group) was created in Houston in 1995 by Jean-Patrick GIRBIG, ten years after he created the EPSG (European Petroleum Survey Group). He chaired at the start. The main purpose was to exchange locational data like coordinate systems and to discuss in-field practices. The target was to improve the quality of the data and reduce errors in exchanges and sales of data. APSG has a close link with EPSG and has adopted the "EPSG database" that is now worldwide recognised and used by several software companies.
